About the ALF323 Clutch Pedal Force Sensor
The ALF323 is a compact, high accuracy low profile loadcell for measuring clutch pedal application forces. The loadcell is robust in construction with a maximum force range of 1kN (100kgf). Its multi-hole fixing allows simple attachment to any shape pedal using screws or cable ties. The low profile design maintains the clutch pedals ergonomic geometry. Low mass aluminium alloy construction reduces the mass influence upon the clutch pedal in dynamic testing.
If you require other force ranges the ALF304 or ALF322 may be suitable.
We are happy to design variants of this loadcell to meet your specific requirements.
The standard range is manufactured in aluminium alloy.
Notes
1. AL = Applied load.
2. RL = Rated load.
3. Temperature coefficients apply over the compensated range.
Connections
The ALF323 is fitted with 2 metres of flexible polyurethane jacketed 4 core screened cable.
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.
