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 CostBuilt-in Volume BoosterSmall SizeField ReversibleLow Air ConsumptionMounts at Any AngleConvenient External Span & Zero Adjusts (Except for Explosion Proof Models)Wide Supply Pressure RangeLow Supply Pressure SensitivityApplications:Valve ActuatorsDamper and Louver ActuatorsValve PositionersControllersRelaysAir CylindersClutches and BrakesLiquid, Gas and Slurry Processing InstrumentationHVAC SystemsPaper Handling ControlsTextile Processing SystemsEnergy Management SystemsPetrochemical Processing SystemsSplit Ranging State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
