Bolt Force Washer Load Cell | Donut Style With Through-Hole

CAPACITY
4TF - 80TF

NON-LINEARITY
±1% RO

RATING
IP67

The FW compression load cell has a compact bobbin style design. It is manufactured from stainless steel and has an 8 strain gauge Wheatstone bridge as standard.

This load cell is ideal for bolt torque monitoring projects with bore sizes and capacities available to suit most applications. Optional hardened or spherical washers are also available to help improve performance in-situ. 

The capacity, height and bore size of this load cell is customisable - we can adapt its design to suit your application if required.


To view the full specification, please download the product datasheet.

If this load cell doesn’t quite suit your application, get in touch to discuss your requirement in more detail with one of our experienced team members.
