Condor pressure switch MDR-F

The Condor pressure switch series MDR-F can be universally used and are
suitable for:

• Monitoring and controlling the pressure of liquids or gaseous media in pipelines, tanks, vats, pressure vessels and installations.
• Tasks in process control, cooling, pneumatics and hydraulics.
• Automatic switching of pump and compressor motors for supplying water to dwellings, booster pumps, fire-fighting equipment and on compressed air systems.

Mode of operation:

The pressure of the monitored medium operates against a diaphragm, bellows or a plunger all of which have different media resistance. Switching operation is carried out with the use of a micro switch ensuring flutter-free switching.

When the pressure reaches the upper switching point, the micro switch contacts change position. In normal cases e.g. a connected motor is switched off (up to 550 watts direct or using additional switches like a contactor etc.). Should the pressure fall below the lower switch point, then the micro switch contact returns to its default position and the motor is switched on.

The upper and lower switching points can be set independently using a screw driver. Both switching points can be read off the scale.
