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 Applications The Type 1001’s precisely regulated pneumatic output can be used to operate: • Valve actuators • Louver and damper actuators • Valve positioners • Relays • Clutches and brakes • Controllers • Air cylinders Industry Applications Include: • Liquid and Gas Processing • Pulp and Paper • Petrochemical Processing • HVAC Systems • Textile Productions • Energy Management • Environmental Control • Medical Equipment Calibration Adjustments The Type 1001 contains multi-turn Zero and Span adjustment potentiometers which are accessible on NEMA 1 models by sliding the cover window Type 1001 I/P & E/P Transducers open to its first detent position. Pots are clearly distinguished by legend on the cover. On NEMA 3R and 4X models, the cover should be removed to reach the pots (marked Z for zero and S for span). Adjust the pots clockwise to increase Zero and Span as required to optimize factory set output with appropriate input signal and supply pressure applied. Damping Adjustment To eliminate undesirable system oscillation, the Type 1001 features a unique damping adjustment. The output response is optimized to varying downstream volumes by adjusting the feedback time constant of the coil drive amplifier. This is accomplished on NEMA 1 models by sliding the cover window open to its second detent position to expose the single-turn Damping Potentiometer (remove the cover on NEMA 3R and 4X models). To optimize response, turn the pot fully counterclockwise until system oscillation is just eliminated. System oscillation may be observed by monitoring output pressure or by observing the behavior of directly actuated system components in response to a changing input. Mounting The Type 1001 transducers are designed to be position insensitive. They can be panel, valve, or pipe mounted at any angle (see NEMA 3R limitation) without a need for in place recalibration. Panel mounting can be either direct or with the bracket furnished with each unit. Mounting holes are located on the bottom and side to provide maximum mounting flexibility. Users may order the optional DIN Rail Adapter or a bracket suitable for either valve or 2" pipe mounting. Special pipe clamps may be ordered as a separate kit.
