The Type 1001 is a patented family of electro-pneumatic instruments that is 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.
* Built-in volume booster provides flows up to 12 SCFM
* Easy access zero and span adjustment
* Damping pot prevents over shoot and hunting
* Mounts at any angle (NEMA 3R limited)
* Virtually no sensitivity to supply pressure changes
* Removable orifice (screw) for easy maintenance
