Model 305

The miniature force transducers of the model series TesT 305 are used almost everywhere, where existent space capacities provide no other opportunity. Due to their compact dimensions these sensors have to be adapted very accurately. Thus, they reach a long product life at very high accuracy. These sensors, which are made of stainless steel, are suitable for the measurement of compressive forces.

Electrical Force Transducers – Model 305

n Capacities: 500N bis 20kN
n For compression
n Stainless steel
n Very small dimensions
n Sensitivity: 1mV/V
n High accuracy
n For dynamic applications
n TEDS module available

The electrical force transducers of the model series 305 fit in minimal spaces because of their very small dimensions. The miniature force transducers that are made of stainless steel provide precise measurements as well as a long product life and should be adapted accurately before use. They are well suitable for compressive forces and on demand they are also available with a TEDS module for an automatic sensor recognition. In this case the TEDS module will be installed inside the plug.
