Abstract : A protective circuit was designed which reduces the possibility of damage to the piezoresistive element of a transducer due to test discharges of the full measuring current. This modification of the power supply consists of a crowbar circuit which shunts the power supply output with a low impedance at a preset time after power supply trigger.
