Current To Pressure Transducer- Series 2200
Intrinsically Safe or Explosion-Proof Two-Wire, Accuracy to 0.15%
The Dwyer Series 2200 Current to Pressure Transducer combines low cost, accuracy and minimal air consumption with field-proven technology. Versatile design features a rugged, compact housing with a choice of FM approved explosion-proof or intrinsically safe operation when used with a suitable barrier. This transducer utilizes a practically weightless membrane that is electromagnetically positioned over the air flow, consuming minimal air and electrical energy while providing an accurate, precise output pressure signal. This low-mass membrane yields an output that is virtually unaffected by shock, vibration or mounting position. By employing an internal feedback network, the I/P responds quickly to step input changes, and by balancing air supply and exhaust, provides control stability while delivering accuracies of ±0.15%. The pneumatic control signal is enhances by an internal volume booster. The unit features easy access to zero and span adjustments, plus controls for field selectable direct, reverse or split-range operation.
