The 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 & 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 Watson McDaniel TA987 Air Filter/Regulator is recommended for filtering
and regulating the pressure of plant compressed air, and for delivering clean,
dry air at the proper pressure to pneumatic control devices.
