Model 31 Tension/Compression Load Cell (Universal Load Cell)

Stainless steel
Infinite resolution
Miniature



A load cell or force sensor is a device which converts load or force into an electrical signal.

Tension/compression load cells measure the force applied to the centre threads of the load cell.

Care should be taken to ensure that the load sensor is not exposed to load or force in excess of its capability. The range of tension/compression load cell (universal load cell) selected should therefore be appropriate for the maximum force (including transient forces) that can be applied to it.

One particular feature of this transducer is its very small size

This series of transducer is a strain gauge type transducer and has a mV output which may require an amplifier. We can offer a variety of high quality, low noise and high precision strain gauge amplifiers.
