A new Bluetooth app for smart devices, named after Straightpoint’s (SP) Handheld plus display unit, is now available for download and easy connection to the manufacturer’s recently launched range of load cells that boast the same technology. The innovative pairing is set to revolutionise the way data is captured and supplied in below-the-hook and other force measurement applications.
The HHP app, available on iOS and Android platforms, uses Bluetooth (wireless technology for exchanging data over short distances) to collect information from a single load cell up to 50m away. Further, the app can package up the data collected and send it onto a recipient in the form of an Excel spreadsheet.
The free-of-charge app adds convenience and cost efficiency to the vast majority of applications involving SP equipment where a single force measuring device is used in close proximity to a reader and / or data-logging system. Until now, wireless readings were only possible on the handheld system, while the company’s multiple wireless load cell controller (SW-MWLC) software was required to convert data into another format.
Those existing products remain integral to the SP offering; the Handheld plus has a range of up to 700m (2,300 ft.) and the SW-MWLC package displays and logs data from up to 100 SP wireless load cells simultaneously. This is cutting-edge technology in its own right but is suited to more demanding, specialist applications for which the app is not designed. Capacity isn’t a dictating factor to its use, although the heavier the load the more likely it is that multiple load cells will be used and the operator will be at a greater distance from it.
David Ayling, director at SP, said: “We’ve been experimenting with Bluetooth technology for some time—it’s been used with our Clamp On Line Tensionmeter (or COLT)—but that research was part of a journey towards the landmark launch of the new load cells and accompanying app. Distributors and partners have lauded its ability to send reports from the same device that captures the data and noted the inherent convenience of having the app on a smart device that is on their person.”
The HHP app is user friendly but can be downloaded in simulation mode so users can practice before utilising it in a real-life application. It is compatible with any SP product that fits the usage criteria, which can be selected via a straightforward menu. Units of measurement and calibration settings are among other variables that can be specified with equal simplicity.
Ayling concluded: “The launch of the Bluetooth range chimes with a gravitational pull towards IoT [Internet of Things] and could be game-changing in that we’re not aware of any other solutions on the market that harness the benefits of this technology through a mobile app. Once again we’ve demonstrated our pioneering intent and we’re keen to monitor uptake through download numbers in the coming weeks.”

Seattle, Washington-based Arxcis Inc., a crane inspection and operator safety training company, uses a 25-ton capacity wireless shackle load cell (or loadshackle) from Straightpoint (SP) to keep personnel at a safe distance during load testing.
Arxcis is accredited to carry out such tests on a variety of on and offshore equipment, including floating cranes and derricks; vessels; material handling products; and loose rigging gear, including wire rope and other below-the-hook equipment. Its customers are principally concerned with meeting the requirements of the Occupational Safety and Health Administration (OSHA).
Jeff Williams, co-owner, president and chief inspector at Arxcis, said: “We also have certifications to inspect cranes and other equipment used in longshoring; shipyards and ship breaking; and the construction industry. We use the SP loadshackle mainly in the load testing portion of our operations, whether doing a static test or weighing the test weights themselves.”
Williams, who has been inspecting cranes and below-the-hook equipment for 22 years, explained that the wireless capability of the load shackle—data is transmitted wirelessly utilising the latest in IEEE 802.15.4 (2.4 GHz) technology—is essential to keeping personnel safe.
“When load testing some marine cranes we will load the crane to 125% of the rated load for that radius and, if there’s a catastrophic event, one doesn’t want to be in close proximity of the hook,” he said.
A number of recent case studies represented typical Arxcis applications. In a bollard pull test at Platypus Marine, of Port Angeles, W.A., for example, the loadshackle was attached to the vessel by two straps and then a long line was sent out from the stern and attached to a fixed point. The vessel then ramped up to full power and the poundage was read and recorded every 30 seconds for 15 minutes.
In another application for the University of Washington, aboard the Thomas G. Thompson research vessel, the loadshackle was attached to the top of a movable A-frame gantry; a water bag was then filled to the predetermined weight. “In this case,” he said, “the bag was filled to 14,000 lbs. and then the frame was cycled through its full range. After the dynamic test the frame was then filled to 20,000 lbs.”
Aboard the same vessel, the loadshackle was integral to safe completion of a static load test of a hydro boom that extended out from the starboard (right) side of the boat to lower scientific equipment into the water.
If required, SP’s wireless data logging software allows for simultaneous control, display and real time data logging of up to 100 SP telemetry load cells. Logged data is captured in a .csv file format and opens in MS Excel providing easy visual presentation, analysis of logged data, and simple test certificate generation.
Williams concluded: “The SP equipment has been flawless; the durability, accuracy and transmission range of the load cell is stellar.”

SP Launches Multi Operation Survey System
Load cell manufacturer Straightpoint (SP) has teamed up with measurement equipment specialist Tarka-Systems B.V. to add to its extensive range a product that can be left at a jobsite for a period of time and capture data from up to six monitoring devices.
The Multi Operation Survey System (MOSS) features six, 4-20 milliamp (mA) inputs that collect information when multiple types of data are required, captured by load cells, thermometers, anemometers and other technologies. The MOSS, boasting USB data storage capability, is typically applied where data needs to be gathered over a period of time, say, when conditions are likely or known to change.
Originally designed for the marine industry, where wind speed and sea state might be among variables, the product is provided in an IP67-rated, portable case, mounted on which are the connectors (also IP67 rated) that can be used while the case is closed, offering protection from the elements—even snow and ice. The MOSS has also been successful in construction and infrastructure applications where other demands are placed upon it.
David Ayling, director at SP, said: “It is both compatible with our range of force measurement products and suited to use in many of the environments where SP equipment is already commonplace. The SP brand is synonymous with technologically advanced, durable equipment and we look forward to opening new markets for Tarka’s innovative solution.”
The MOSS’s case provides readout, presentation and storage of multiple sensor signals and houses the system’s key components, including screen with user control buttons and battery supply with status display. The battery lasts for up to 24 hours but an additional power pack extends this to up to five days for applications where monitoring is required over longer time periods.
Henry Wijgerse, owner of Tarka-Systems B.V., explained that the product was to some extent conceptualised during his time at Maritime Research Institute Netherlands (MARIN), which is principally engaged in nautical research.
He said: “I spent over a decade working on oil rigs and ships, and detected a need to provide the market with the technologies that we were using to capture and then provide it with data. However, MARIN wasn’t interested in product centric initiatives—it was a research organisation—hence the formation of Tarka in 2011.”
Wijgerse added: “[Two years later] a customer from the salvage sector wanted a solution for gathering data about a stranded ship, including the draft, angle of wreck, water depth, and how deep the vessel was in the sand, so they could calculate the towing force required to complete a rescue. It wasn’t called the MOSS at the time, but our solution was the blueprint from which future innovations have been based.”
Ayling concluded: “Since we’ve introduced Mike Neal [product sales engineer] and Marcus MacDonald [machine shop supervisor] to the company, we’ve generated an increasing number of enquiries for custom products with autonomous logging, but it might not be practical to leave a laptop, for example, exposed to the elements. The MOSS fills that gap in our offering.”
Custom versions are available upon request.

SP Load Cell Helps School STEM Club Attempt to Break Sound Barrier
Straightpoint (SP) has donated a 5t capacity Radiolink plus wireless load cell, which is being used as a key component in a Nottinghamshire, UK school STEM club’s outlandish, but entirely plausible, attempt to send a rocket car through the sound barrier next year.
The science, technology, engineering and mathematics group at The Joseph Whitaker School meet for three hours every night. And the dedication to extra curricular studies is paying off. Sending a car hurtling along a wire rope, it already has a Guinness World Record—set at 533.1mph—but has realistic ambitions to smash the sound barrier, which is approximately 765mph, in 2018.
The young engineers rig a 5t electric winch to a 3t Land Rover that is, in turn, rigged to the load cell and onto the main cable where the rocket motor in the car is launched; the cable runs 700m to the school minibus. The team also employs SP’s wireless data logging software on a laptop for dynamic force measurement. This allows them to log data at 200Hz from the Radiolink, providing a clear picture of the current stress in the guide cable and any stresses on the cable during launch.
Phil Worsley, teacher of technology at The Joseph Whitaker School, said: “We started off with 1.5mm steel guide cables and the rocket cars would ‘waggle’ along the loose cable. We then employed winches, starting with hand units and then up to 1t electric models. Once we were able to measure the force in the cable, thanks to Straightpoint, we could then launch on a known value—and reproduce it with confidence.”
He added: “The cable tension has always been a grey area and the only evidence of the rocket car going awry, is the ‘pig-tailing’ we find after the event. The load cell allows us to measure tensions and stay within the safe working load limits of the wire rope while optimising conditions for the rocket car in our record attempt. We treat safety as our number one focus and the load cell is integral to that.”
In the limelight
Straightpoint is not the only company to take note of the impressive track record of Worsley’s ‘after-school club’. Santa Pod Raceway is looking into an alternative for the guide wire tensioning points, while Rolls-Royce is providing materials science education and access to titanium for wheels. Easy Composites, Swansea University, Bloodhound, and the Discovery Channel are others to support, supply and / or cover the ongoing, landmark project.
Worsley said: “Breaking the sound barrier does not constitute a record, but imagine the headline—‘school children break sound barrier!’ And we’re not stopping there; how much further could we go? Could we emulate the magnificent Bloodhound car, at 1,000mph?”
The sound barrier attempt is slated for summer 2018, where the latest version of the car will likely go faster than it has travelled before. The rocket cars are powered by ammonium perchlorate, a frequently used oxidizer in most modern composite rocket propellant formulations.
Worsley said: “We have so far officially achieved 628mph. This is not the maximum speed that this car can go, as just as the car passed the time trap it abruptly broke up and turned over. We have completely redesigned it to have a lower and longer rear stabiliser with a much stronger chassis design. The cable guide system has also had a huge upgrade; we will be using a 6mm guide cable and loading it with the optimal tension to reduce any whip that might be occurring.”
The first car (Mach 1) was 740mm long, 100mm high and the main chassis was only 60mm in width. The rear wheels were 280mm apart to reduce the possibility of the car overturning. The weight of the car was approximately 1100g without the rocket motor, which weighs 868g, giving a total weight of 1,968g. The second edition (Mach 2 or ‘Big Mac’) is the same length and width but due to the double rocket capacity, is 130mm high. It weighs approximately 1,300g, while the rocket weight will be up to a maximum of 2 x 868g, giving a maximum full load of just over 3kg (3,036g).
Worsley concluded: “We could not be where we are now without this load cell and Straightpoint’s generosity. STEM is difficult to learn from a book. It has to be experienced through some medium that allows students to see, hear and feel something and have ownership over changes that they create. STEM is best understood through discovery learning.”

SP Appoints New Marketing Executive
Straightpoint (SP) has named Phil Roch marketing executive, as the load cell manufacturer looks to leverage his extensive expertise in technical content, videography and events.
Roch, who has an entertainment technology degree, brings a wealth of experience to the company, most recently as marketing and technical content producer in the security technology sector. He has enhanced previous employers’ visibility through written materials, a variety of videos, and events of all types, including those that engaged audiences in the aviation and naval sectors. SP is noted for its growing presence in the aforementioned sectors among a multitude of others.
Roch said: “SP is already an effective communicator with a proven track record of successfully engaging its many markets across the world. However, it identified an opportunity to expand the marketing team and add breadth to the volume of content and the platforms on which it is shared, whilst retaining certain hallmarks in quality and tone.”
Early written projects are likely to include content for the constantly evolving website and documentation to enhance the sales team’s endeavours. With the majority of online content being consumed by video—a trend that is set to continue—Roch will also overhaul the way SP currently communicates via the popular medium.
He said: “SP has already had some success through video and my aim is to build on that initial presence. Over 80% of online traffic currently is video, which demonstrates the potential. Audiences can expect to see more promotional, elemental and instructional videos, in addition to talking head-style pieces and interviews with the company’s leading figures.”
Trade media has already reported extensively on SP’s intentions to exhibit at a record number of events in 2018. While Roch will support this promotional activity, he is also expected to use the firm’s Havant, Hampshire headquarters as a platform to showcase product and expertise to selected target audiences.
He explained: “One of the most effective ways of building trust in a manufacturer and increasing awareness about its product range is to invite people to visit a facility and see the operation first hand. We can supplement such visits with tailored presentations and other content to ensure individuals or delegations leave with a mindful of knowledge and key takeaways.”
Roch hopes to harness the power of a world-class workspace that was an appeal to him when he considered the position. He said: “My first impressions of all departments of the company, from the new machine shop to the offices next-door, were that it is an extremely well organised operation. Upon joining the company and meeting the team, it’s further apparent that SP has a super-engaged workforce, passionate about the products and its customers. There’s a terrific atmosphere [here] and I’m excited about showcasing that to a greater number of people over the coming months.”
David Ayling, director at SP, said: “We see ourselves as pioneers in our sector and a key component of retaining thought leadership status is communicating on a regular and multifaceted basis with existing contacts in addition to prospective partners and customers. It’s going to be interesting to follow Phil’s content and marketing pathways to that end.”
