F326 Reaction Torque Transducer

The F326 fits between a motor and its mounting structure acting as a low profile coupling or adaptor plate. The motor shaft passes through the centre of the F326, the resultant torque reaction on the motor stator is equal and opposite to the shaft torque. Torque is transmitted from the motor stator through the F326 transducer to the earth structure or chassis.

This makes the F326 suitable for many process applications, examples are;

  • Bulk powder handling - mass flow measurement
  • Rheology - liquid viscosity measurement
  • Mechanical handling - conveyor belt drive torque

F326 transducers can be designed for most motor drive applications where the motor is itself static. We are happy to design variants of this transducer to meet your specific requirements. Please consult our engineering department.

Details of all our loadcell families can be found in the Loadcell Specifier Guide.

Ordering Codes

See the loadcell ordering code sheet for more details. Add range in the required force units.

Most F326 loadcells are manufactured to special requirements and are given an F326-Zxxxx number.

Notes

  1. AT = Applied torque.
  2. RT = Rated torque.
  3. Temperature coefficients apply over the compensated range.
  4. The motor mass can create an initial zero change and is replicated during our calibration.

Connections

The loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 16-2-4C.

Excitation + = Red, Excitation - = Blue, Signal + = Yellow, Signal - = Green, Screen = Orange.

The screen is not connected to the loadcell body.
