T500 Electropneumatic I/P Transducer (I/P, E/P)


code :

The ControlAir Type-500X converts a current or voltage input signal to a linearly proportional pneumatic output pressure. This versatile instrument is designed for control applications that require a high degree of reliability and repeatability at an economical cost.
The Type-500X is available in two different versions. The lower range model is designed for standard process control applications which typically utilize a 3 to 15 psig (0.2 to 1 BAR) output. The extended range unit provides up to 145 psig (10 BAR) output for higher pressure industrial pneumatic and process control system requirements.
