Condor High performance pressure switch MDR 2

The high-performance pressure switch for switching motors (compressors and pumps), available in various versions and with optional accessories. The pressure switch has been successfully tested and certified by the KEMA KEUR Test and Certification Institute. To determine the pump or compressor run-time, the MDR 2 can be fitted/retro fitted with an (optional) operating hours counter. The operating hours counter is available as a kit. The kit consists of an operating hours counter for 230 V, and a perforated MDR 1 cover with/without On/Off switch. Its robust and hard-wearing design ensures a long service life, also under high loads. The MDR-2 pressure switch is fitted as standard with the possibility for pressure difference adjustment. Two adjusting screws permit switching point and hysteresis to be adjusted, whereby the cut-out point is first adjusted via the main pressure spring and then the cut-in point via the pressure difference setting. 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.
