F302 Low Profile Diaphragm Loadcell

Geometry: Low profile axial loadcell for use in force measurements in compression.

The F302 is designed for force measurement in compression. The loadcell is designed for simple mounting on a smooth flat surface. It has an integral load button and is supplied with three tapped holes and three clearance holes enabling fixing or location from either above or below the loadcell.

In the event of structural failure of the loadcell the resulting vertical movement of the supported load will be very small.

We are happy to design variants of this loadcell to meet your specific requirements. Please consult our engineering department.

Details of our other loadcell families can be found in the Product Guide.

Range (kN) Stiffness (N/m) Range (kN) Stiffness (N/m) Range (kN) Stiffness (N/m)
5 1.0 x 108 25 1.1 x 109    
10 2.9 x 108 50 2.2 x 109    

Notes

  1. AL = Applied load.
  2. RL = Rated load.
  3. Temperature coefficients apply over the compensated range.
  4. The load must be applied directly through the central loading axis.

Connections

The loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 7-1-4C.

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

The screen is not connected to the loadcell body.

When this loadcell is rationalised the resistors are housed in a capsule located in the loadcell cable 100mm from the free end. Capsule dimensions are Ø10mm by 57mm.
