Type 1000 T1000 Extended Range I/P Transducers

Brand: Marsh Bellofram Group of Companies

The Type 1000 Transducer is an electropneumatic device that reduces a supply pressure to a regulated output pressure directly proportional to an electrical input signal.

The Type 1000 accepts a wide range of supply pressures, ranging from a minimum of 3 psig (0.2 BAR) above the maximum output up to 100 PSIG (6.9 BAR). An integral pneumatic volume booster is included in the design to provide high flow capacity (up to 12 SCFM/339 SLPM). 

Model selections include general purpose, NEMA 4X Type, extended range, high relief, intrinsically safe, and explosion proof.
