Watson Smith, 4-20 mA input 0.2 bar to 2 bar

Explosion-proof Failsafe Type 140

Electronic current-to-pressure converter utilising advanced closed-loop operation to allow accurate high-resolution pressure control via a 4-20mA input signal. Fail-safe operation ensures that output pressure falls to zero on loss of input signal.

I/P & E/P Converters

I/P converters are electro-pneumatic instruments that will change pneumatic pressures in response to varying electrical current and voltage input signals. They have extensive application potential in both industrial and process systems, for control of cylinders, valves, valve positioners, relays, brakes and clutches. The converters can be mounted in control rooms or in the field, and have zero and span settings that are adjustable from the front face of the instrument. Failsafe converters are available which will cause the output pressure to fall to <15mbar (0.2 psig) in the event of power failure or loss of input signal.
