Fisher™ 4195K Gauge Pressure Indicating Controller
Fisher 4195K Controller
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 deliver 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, and differential gaps for on/off control. 4195K controllers are used in industries where accurate pressure control and process monitoring are required.

  • Adjusting the set point, the zero and span of the process pointer, and switching between direct and reverse action are accomplished quickly and without special tools.
  • A 4195K series controller can be mounted directly on the actuator or it can mount on a pipestand, wall, or in a panel.
  • The simple design and low mass of internal parts allow a 4195K series controller to withstand the vibration levels encountered in most plant environments.
  • The relay and nozzle design reduces steady-state air consumption to as low as 0.09 m3/hr (3.5 scfh); less than the 6 scfh requirements set for the oil and gas industry by the US Environmental Protection Agency (New Source Performance Standards Subpar
  • Tough, plastic housing resists such corrosive environments as chemical plants and the salt spray atmosphere on an offshore oil platform.
