Marsh BelloframSeries 1000 Current to Pressure Transducer

Bellofram Type 1000 Transducer
 Marsh Bellofram Type 1000 I/P & E/P Transducer
The type 1000 transducer is an electropneumatic device that reduces a supply pressure to a regulated output pressure that is directly proportional to an electrical input signal. It uses a supply pressure between 125 and 700 kPa (18-100 PSIG). An integral pneumatic volume booster is included in the design to provide high flow capacity up to 12 SCFM.
Applications:
  • Valve actuators
  • Damper and louver actuators
  • Valve positioners
  • Controllers
  • Relays
  • Air Cylinders
  • Clutches and Brakes
 Features:
  • Low Cost
  • Built-in Volume Booster
  • Small Size
  • Field Reversible
  • Low Air Consumption
  • Mounts at any angle
  • Convenient external span and zero adjustments
  • Light Weight
