      • Control pressure switch for AC voltage
      • for pumps / for compressors
      • High-pressure switch up to 250 bar
      • for oil, water, and air
      • plastic piston as pressure sensor element & stainless steel pressure connector
      • gold-plated contacts "G" (optional)
      • Motor switching capacity 0.55 kW
      • Cut-out pressure ≤250 bar
      • 1-pole (change-over)

      MDR-F pressure switches are available in different versions and are suitable for universal use. Depending on version, they are used for monitoring and control of pressure in liquids and gases, for process control tasks, for pressure monitoring in cooling & lubrication systems and for automatic switching of compressor and pump motors.

      The MDR-F..HH pressure switch (version as high-pressure switch up to 250 bar) is fitted as standard with the possibility for pressure difference adjustment. Two adjusting screws (P1 und P2) permit switching point and hysteresis to be adjusted, whereby the cut-out pressure is adjusted with screw P1. Pressure difference and thereby the cut-in point is adjusted with screw P2. By selecting a pair of values for cut-in and cut-out pressures, an intersection point is determined in the diagram. If the point lies within the shaded area, this pair of values can be adjusted on the pressure switch. If the point lies outside the shaded area, this pair of values cannot be adjusted on the pressure switch.

      Because of the wide range of pressure switch versions, please contact us if you have questions on a special application or have technical requirements. As a manufacturer of pressure switches and controls, we offer a wide range of services, including standard and customer-specific solutions for individual applications.
