FISHER Controller 4150 / 4160K

The 4150K and 4160K Series controllers,  compare a sensed process pressure (ordifferential pressure) with an operator-adjusted setpoint, and send a

pneumatic signal to an adjacent control element that maintains the process pressure at or near the set point value. The 4150K Series

transmitters sense process pressure and send out a pneumatic signal, usually to an indicating or recording device that directly indicates the process

pressure
