LoadSafe - Wireless Compression Load Cell is available ATEX and IECEx approved to Ex ia II T4 Ga for use in zones 0, 1 and 2 hazardous environments (gas and is designed for the on and offshore oil and gas, chemical and other industries with challenging hazardous areas.

No longer hindered by troublesome and hard to maintain cables, large scale projects can be completed in a fraction of time previously required. Maintenance costs are all but eliminated due to the absence of cables and connectors, and the product's flexibility opens the door to a large number of applications in hazardous areas such as drilling platforms, silos and heavy lifting projects replacing unwieldy and inaccurate hydraulic loadcells previously used in similar applications.

SP's Wireless Compression Load Cells are machined from high-grade stainless steel, providing excellent strength and corrosion resistance. The heavy-duty, compact load cell utilises Straightpoint's advanced microprocessor based electronics and benefits from unrivalled resolution and accuracy. Data transmission is handled by the Straightpoint wireless systems proprietary transport protocol, is unmatched in performance and capable of a licence free transmission range of up to 500 metres or 1640 feet.
Load data is transmitted wirelessly utilising the latest in IEEE 802.15.4 (2.4 GHz) technology providing safe, high integrity, error-free transmission of both static weight and dynamic load to our SW-HHP-ATEX handheld controller for use in hazardous areas.

This latest range of compression loadcells utilise easily sourced Energizer® Ultimate Lithium AA Batteries and features advanced circuitry designed to protect the unit from damage associated with incorrectly installed batteries. This advanced circuitry extends battery life eliminates issues associated with rechargeable battery pack charging, failure and replacement.
