Description Specifications Literature Description The Marsh Bellofram Type 1000 is an electro-pneumatic transducer that reduces a supply pressure to a regulated output pressure directly proportional to a converted 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 provides 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. The 4-20 mA input, 3-15 PSIG output model can be recalibrated to provide 3-9 PSIG or 9-15 PSIG output for split ranging applications. Features: Lightweight and Low Cost Built-in Volume Booster Small Size Field Reversible Low Air Consumption Mounts at Any Angle Convenient External Span & Zero Adjusts (Except for Explosion Proof Models) Wide Supply Pressure Range Low Supply Pressure Sensitivity Applications: Valve Actuators Damper and Louver Actuators Valve Positioners Controllers Relays Air Cylinders Clutches and Brakes Liquid, Gas and Slurry Processing Instrumentation HVAC Systems Paper Handling Controls Textile Processing Systems Energy Management Systems Petrochemical Processing Systems Split Ranging State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
