Rotork Fairchild's T7500 I/P Transducers Deliver High Accuracy at Very Low Pressures

Rotork Fairchild's T7500 I/P Transducers
Precise pressure control, where output pressures must be accurately held at low pressures down to 70 mBar (1 psi), has traditionally been a difficult task for industrial instrumentation. Rotork Fairchild's T7500 range of transducers is specifically designed for these low pressure control systems with set point accuracy of 0.1%, even at pressures of less than 100 mBar.

T7500 transducers accept supply pressures between 1.3 and 2 Bar (20 and 30 psi) with mA or VDC control signals to deliver critical high accuracy output ranges of 0-350 mBar (0-5 psi) and 0-1 Bar (0-15 psi). Flow configurations of 85 l/m or 200 l/m suit a wide range of application requirements. In addition, the T7500 can be ordered with DIN plug, NPT conduit or terminal block electrical connections styles to suit assembly requirements.

The 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.
