TA901 Electropneumatic I/P Transducer
Brand: Trerice Gauges & ValvesThe Trerice TA901 Electropneumatic (I/P) Transducer converts a milliamp current signal to a linearly proportional pneumatic output pressure.
This transducer is designed for control applications that require a high degree of reliability and repeatability.
The TA901 is used in the control operation of valve actuators and pneumatic valve positioners in the petrochemical, HVAC, energy management, textile, paper, and food and drug industries.
The TA901 I/P Transducer is tested and approved by Factory Mutual as Intrinsically Safe Class I, II and III, Division I, Groups C, D, E, F and G when installed in accordance with the Installation, Operation and Maintenance Instructions.
It should be installed in a vertical position in a vibration-free area. The Trerice TA987 Air Filter/Regulator is recommended for filtering and regulating the pressure of plant compressed air and delivering clean, dry air at the proper pressure to pneumatic control devices
