ALF252 Pancake Force Sensor
Low profile axial loadcell for use in force measurements in tension and compression
Key features
- Full load range: 1kN, 2kN, 4kN, 8kN, 10kN
- Tension, compression and bi-directional
- Non-lin./hysteresis: 0.1/0.1% RL
- Dimensions (mm): Ø99 x 27
About the ALF252 Pancake Force Sensor
With bi-directional versions there is a small difference between the output signal for compression and tension. All standard bi-directional loadcells are calibrated in both modes and the output for each direction is stated on the test / calibration certificate.
The ALF252 is ideal for engineering force measurements particularly in applications where there is a limit on the height of the loadcell. It can be used for test machines and a wide range of general industrial applications.
We are happy to design variants of this loadcell to meet your specific requirements. Versions can be manufactured for fully compensated operation up to +250°C. Please consult our engineering department.
Geometry: Low profile axial loadcell for use in force measurements in tension and compression.
All standard ranges are manufactured in stainless steel.
Notes
1. AL = Applied load. 3. Temperature coefficients apply over the compensated range.
2. RL = Rated load. 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 7-2-4C.
Excitation + = Red Signal + = Yellow Screen = Orange
Excitation - = Blue Signal - = Green
Reverse the signal connections to obtain a positive signal in tension mode. The screen is not connected to the loadcell body.
