High Pressure Limit Switch

Limit switch is a switch operated by the motion of a machine part or presence of an object they are used for control of a machine as safety interlocks or to count objects passing a point.

High pressure limit switch.

High and low pressure switches may be installed on the refrigerant tubing of some air conditioning systems. Designed for high pressure applications these switches electrically activate automated controls or alarms when a set pressure is reached. Long distance light beam. They are often used in pump and hydraulic power applications.

The switch makes sure the furnace is operating safely and at its desired settings. They can be wired normally open no or normally closed nc. It s also known as a fan limit switch or simply a limit switch. Compact safety limit switches.

The high side if equipped with a high pressure switch should be set according to the manufacturer s recommendation. Rated ip69k these switches can withstand high pressure high temperature washdowns and temporary submersion. However they are commonly found on heat pumps. In the case of a heat pump in cooling mode the high pressure switch is used to make sure that outdoor unit can reject heat with the outside air.

Shorter and thinner than other safety limit switches these are sized to fit tight spaces. This pressure will be based on specifications for maximum pressure for the refrigeration systems high side and the type of refrigerant used. The key is to protect the compressor from extremely high pressures that could damage.
