Bellofram Type 1000 I/P (Current to Pneumatic) Transducers

The acknowledged industry standard, Bellofram’s Type 1000 transducers reduce a supply pressure to a regulated output pressure proportional to the 4-20 mA electrical input signal, typically used to provide air to an actuator to control a damper or valve positioner. T1000 supply pressure can range from 3 PSIG above maximum regulated output up to 100 PSIG.
