TE CONNECTIVITY’s washer load cell, model FMT, isdesigned to measure clamping and screwing forces. The sensor
design reduces the hysteresis and sensitivity variations
associated with torque generated by friction during tightening.
The FMT has a high stiffness and can be used in static anddynamic applications.
With a long standing experience as a designer andmanufacturer of sensors, TE CONNECTIVITY often works withcustomers to design or customize sensors for specific uses andtesting environments.
On request, Instruction documents can be provided toease the selection and use of our sensors and provide helpfultips.

Load Washer CellDIMENSIONS & WIRING SCHEMATIC (IN METRIC AND IMPERIAL)
Wiring Schematic

Safe practice:Due to the FMT’s small size and stiffness, a certain number of mounting
precautions should be observed during installation:- The force should be uniformly distributed over the surface of the sensor.
- Surfaces in contact with the sensor should be uniform and parallel.
- We recommend that washers (supplied by TESS) be mounted between
the surfaces and the sensor so that the washers are crushed during
tightening. This helps to distribute the force more evenly. Linearity response
is function of this caution.
