MAMCO/LEFOO LF-20 PRESSURE SWITCH
Because of its special internal design this switch can tolerate high pressure spikes inherent on many pressure systems. The switch is factory calibrated but in the case that adjustment is needed in the field the switch offers an adjustment screw to facilitate any fine tuning required. The standard diaphragm employed by Mamco is polyimide (Kapton) making it compatible with many gases and liquids. Several other diaphragm materials are available that make the switch compatible with many mediums. Various electrical terminations are available including ¼ tabs and a metric-pack connector that forms a tight seal when connected.
Because of their ruggedness the Mamco LF-20 is a popular choice for the many OEM applications.

The task of a suction line accumulator is to protect the compressor from so called liquid hammers, which can be caused by the carry over of liquid refrigerant.
The consequence of such a liquid hammer will be the damage of the following compressor parts:
• Suction Valve
• Discharge Valves
• Pistons and Connecting Rods
• Gasket
• Bearings
ESK suction line accumulators incorporate the injection principle, which prevents the transport of liquid refrigeration into the compressor, even if the accumulator is filled up with liquid.

Electro-hydraulic pressure switches are devices, which, when set under pressure close or open electrical contacts. They are widely used in applications where it is intended that, once a pre-set pressure is achieved and exceeded, an electrical switching command or signal should be triggered for further working cycles.
Many different versions (with pressure setting on a dial, with main and secondary switch, screw-on pressure switches) enable their use in many applications.
There is a design related difference of 8 ... 20 % between the upper switching point and the lower switching point. Only the electronic pressure switch type DG 5 E gives provision to select two independant switch points
and to set the hysteresis.
Type DT is an analogical pressure sensor.
