FEMA FD16-327 | LPG Maximum Pressure Limiter, Internal Interlock | 3-16 bar, Ex-i, internal interlock
The FEMA FD16-327 maximum-pressure limiter for liquid gas systems has an internal interlock: once pressure has fallen by about 2.5 bar after a cut-out, it is reset by pressing the red button on the scale side with a tool. Switching pressure is adjustable from 3 to 16 bar, set with the spindle after removing the terminal box. It operates only together with an isolating amplifier.
