Bellofram Type 1500 Pressure Transducer

The Marsh Bellofram Type 1500 electro-pneumatic transducer converts an electrical signal to a proportional pressure output. It provides low-cost precision electro-pneumatic control to actuators, valves, positioners and high-flow controls. Type 1500's compact size and accessibility to ports and adjustments allow the unit to be installed in space-constrained locations or in a manifold.

Marsh Severe service gauges

Marsh Bellofram severe service gauges are expressly designed to provide reliable pressure measurements in harsh and demanding industrial and OEM environments, particularly where pulsation and vibration are a concern. The gauges are filled with liquid to offer a dampening effect, while reducing pointer flutter and potential internal damage to the gauge while in use.
