The Condor MDR1 pressure switch can be used for single phase compressors or as a pressure switch to provide a signal to the control circuit in a larger compressor. You can see just how the product works in the video below.
The differential kit can be used with the MDR1 pressure switch to have greater control over the cut out pressure of the switch. For example, without the differential kit, if the cut in pressure is pre-set to 4 bar then the cut out pressure would be set to 5.4 bar.
With connecting the differential kit to the pressure switch, if the cut in pressure is pre-set to 4 bar then the cut out pressure can be adjusted to be set to between 5.4 bar & 8 bar. Please see data sheet for more information.
On the underneath of the MDR1 switch there is an unloader valve with a 6mm push in connection. The function of the unloader valve is to remove the pressure from the piston of a compressor so that when it re-starts it can move freely and prevent the motor from stalling.
The MDR1 pressure switch is supplied with a delayed unloader valve (AEV 1S) as standard. If you need an unloader valve without delay (EV 1S), this can be ordered separately.
Cable glands are included with this product.
Pressure switches for other pressure ranges are available on request.
