Marsh Bellofram Type 2000 I/P Transducers

±0.25% full scale accuracy

Transducers are designed for valve actuating, air cylinders, and controllers. The 4 to 20 mA current input is conditioned to provide a signal directly proportional to the desired pressure output. The piezo-ceramic actuator serves as a control link between electrical input and pressure output. As voltage increases, the force applied by the actuator increases, so as to restrict nozzle bleed and thus increase pilot pressure. The increased pilot pressure applied to the diaphragm causes opening of the supply valve increasing output pressure.
