Electro-pneumatic transducers are used to convert current or voltage input signals to proportional output pressures. They are used for process control in valves, pneumatic relays and flow regulators. The PCD division of Marsh Bellofram designs and manufactures high-precision voltage-to-pressure (E/P), current-to-pressure (I/P), and pressure-to-current (P/I) transducers for a variety of industrial and OEM applications.
Type 1001 IP and EP Transducers from Marsh Bellofram are a patented family of electro-pneumatic instruments, used to reduce a supply pressure to a regulated output pressure which is directly proportional to a two-wire current or three-wire voltage input.
Type 1500 IP and EP Transducers from the Precision Controls Division of Marsh Bellofram. 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, […]
The Marsh Bellofram Type 2000 is a highly robust E/P transducer with typical full-scale accuracy of 0.1%, designed to provide precise electronic pressure control of humid (non-condensing) and oil-laden process gases within harsh industrial environments.
The Type 5000 PI Transducers is a compact, rugged and reliable two-wire pressure transmitter, expressly designed for industrial field service. This precision unit converts a signal pressure input into a precise 4-20 mA or 10-50 mA output.
