Force Transducer With Signal Conditioner Model PCT 108

The development of automatic weighting, packaging and dosing systems made the force sensor one of the most used transducers in the industrial field. In this context, the experiment board model Scitech Force Transducer with Signal Conditioner Model PCT 108, has been designed to enable the development of experiments on subjects concerning force transducers and conditioning systems of the signal supplied by the same transducers.
