Side Mounted Pneumatic Control 137 PNP

The level controller using a float magnetically coupled to a pneumatic control mechanism. It is specifically designed for providing pneumatic pressure output proportional to level, directly or inversely depending on desired control action. Its major applications are for control of pneumatic valves, dampers & actuators in process control. Controllers are in aluminum housing. Bellow assemblies for used in liquids with suspended particles.
  • Pneumatic pressure output proportional to level.
  • Direct or Inverse Control possible.
  • Optional inline air filter for supply port.
  • Options for calibrated pneumatic output.
  • Standard / Slip on flange options.
  • Standard / Horizontal extension float modules.
