Fisher 4195K gauge pressure indicating controllers
show process pressure and set point on an
easy‐to‐read process scale. The controllers compare
process pressure with an operator‐adjusted set point
and delivers a pneumatic signal to a control element so
that process pressure changes toward the set point.
Controller types are available for proportional‐only,
proportional‐plus‐reset, proportional‐plus‐reset‐
plus‐rate, and differential gap for on‐off control. 4195K
controllers are used in industries where accurate
pressure control and process monitoring are required.
