Type 1001 IP & EP Transducer
Brand: Marsh Bellofram Group of CompaniesType 1001 IP and EP Transducers from Marsh Bellofram are a patented family of electro-pneumatic instruments, used to reduce a supply pressure to a regulated output pressure which is directly proportional to a two-wire current or three-wire voltage input.
This design incorporates closed loop sensing of the output pressure to achieve excellent accuracy and vibration stability. It also features a unique damping circuit which can be adjusted to prevent overshoot and actuator “hunting.”
Model selection includes General Purpose (NEMA 1), Rainproof (NEMA 3R), and Watertight/Corrosion Resistant (NEMA 4X). NEMA 4X models are also explosion-proof and all models are intrinsically safe.
Features- 0.1% Accuracy Typical.
- Closed-loop Pressure Feedback Control Minimizes Effects of Vibration, Temperature, Supply Pressure and Mounting Angle.
- Built-in Volume Booster Provides Flows up to 12 SCFM.
- Easy Access Zero and Span Adjustment.
- Damping Pot Prevents Overshoot and “Hunting”.
- Low Air Consumption.
- Mounts at Any Angle (NEMA 3R Limited).
- Compact and Lightweight.
- Virtually No Sensitivity to Supply Pressure Changes.
- Removable Orifice for Easy Maintenance.
