Straightpoint ATEX / IECEX Wireless Compression Load Cell

Durham Lifting’s Straightpoint Wireless Compression Load Cell is taking the heavy lift and structural weighing industry by storm. It is now 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 products 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. Durham Lifting’s Straightpoint Wireless Compression Load Cells are machined from high grade stainless steel, providing excellent strength and corrosion resistance. The heavy duty, compact load cell utilises Straightpoints 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 700 metres or 2300 feet.

Product Description

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 area or wireless Windows PC data logging software package in the safe area. Our wireless data logging software allows for simultaneous control, display and real time data logging of up to 100 Straightpoint 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.


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.
