Model 304

The miniature force transducers of the model series TesT 304 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 available for measuring tensile and compressive forces.

Electrical Force Transducer – Model 304

n Capacities: 1kN bis 50kN
n For compression and tension
n Stainless steel
n Very small dimensions
n Sensitivity: 1mV/V
n High accuracy
n For dynamic applications
n Optional: TEDS Module available

The electrical force transducers of the model series 304 are preferentially used where installation space is scarce and other possibilities for larger devices are not available. If the miniature force transducers that are made of stainless steel have been adapted accurately they convince with a long product life as well as precise measurements. On demand you receive the model 304 also with a TEDS module.
