Straightpoint ATEX WNI Wireless Compression Load Cell

From: £2,502.90

Straightpoint ATEX WNI wireless compression load cell available in capacities from 3.25t to 1000t 

The Crosby Straightpoint ATEX Wireless Compression LoadSafe (WNI).  No longer hindered by troublesome and hard to maintain cables, large scale projects can be completed in a fraction of time previously required. Multiple compression load cells can all connect wirelessly to our range of PC software via a USB dongle, to our iOS and Android app or to our SW-HHP wireless handheld display.


The new Crosby Straightpoint ATEX WNI LoadSafe Compression Load cell approved to Ex ia II C T4 Ga for use in zone 0,1 & 2 hazardous and intrinsically safe load cell.

Using the latest Straightpoint WNI load cells, maintenance and repair 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 the heavy lift, energy, defence, rigging, shipping, and general transportation sectors.

Connected to our wireless centre of gravity software (INSIGHT) the WNI load cell can be used to weigh and verify center of gravity of large and heavy objects which may not be evenly proportioned. The system will report weight on each individual load cell, total weight and C of G in an html report based on ISO19901.

Straightpoint WNI Wireless Compression Load Cells are machined from high grade 17-4PH stainless steel, providing excellent strength and corrosion resistance and making them suitable for the most arduous industrial conditions.
