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.
