The Crosby Straightpoint WNI LoadSafe Compression Load cell – 2.4 Ghz Wireless or Bluetooth Connectivity

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.

Two versions of the Straightpoint WNI are available:

  • RF – Long range 2.4GHz version providing industry leading wireless range of 1000m or 3280ft to Straightpoint SW-HHP handheld plus or INSIGHT software
  • Bluetooth output and can be connected to any smart phone running our free HHP app on iOS or Android at ranges up to 100m or 328ft.

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.
