Description
The Type 1001 is a patented family of electropneumatic 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 explosionproof, 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 over shoot and “hunting”
• Low air consumption
• Mounts at any angle (NEMA 3R limited)
• Compact and lightweight
• Virtually no sensitivity to supply pressure changes
• Removable orifice (screw) for easy maintenance
