Model T7500 Compact E/P, I/P Low Pressure Transducer
Part Number: T7500
T7500 series low pressure transducer converts DC electronic input signal to a proportional low pressure pneumatic output. The transducer employs electronic closed loop feedback in conjunction with a piezoceramic actuator flapper nozzle system in the pilot stage to control the signal pressure of an integral pneumatic volume booster. The volume booster employs a highly sensitive control diaphragm and main valve to accurately control the flow of air to the downstream system in response to the pressure received from the pilot stage. The electronic closed loop feedback senses the output pressure of the volume booster directly to affect the ultimate in accurate pressure control.
