F238 Binocular Bending Beam
The F238 is a compact binocular bending beam loadcell for force measurements. This type of binocular beam is often referred to as a single point loadcell.
The binocular bending beam construction has good moment immunity resulting in very small errors for change in the force application point.
We are happy to design variants of this loadcell to meet your specific requirements. Versions can be manufactured for higher temperature operation. Please consult our engineering department.

Notes
- AL = Applied load.
- RL = Rated load.
- Temperature coefficients apply over the compensated range.
Connections
The loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 7-2-4C.
Excitation + = Red, Excitation – = Blue, Signal + = Yellow, Signal – = Green, Screen = Orange.
Reverse the signal connections to obtain a positive signal in tension mode. The screen is not connected to the loadcell body.
