High Pressure Limit Switch

Rated ip69k these switches can withstand high pressure high temperature washdowns and temporary submersion.

High pressure limit switch.

The key is to protect the compressor from extremely high pressures that could damage. Designed for high pressure applications these switches electrically activate automated controls or alarms when a set pressure is reached. It s also known as a fan limit switch or simply a limit switch. High and low pressure switches may be installed on the refrigerant tubing of some air conditioning systems.

The high temperature limit switch is an important device used in forced air furnaces powered by gas or heating oil. This pressure will be based on specifications for maximum pressure for the refrigeration systems high side and the type of refrigerant used. Compact safety limit switches. 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.

Standardized limit switches are industrial control components manufactured with a variety of operator types including lever roller plunger and whisker type. Shorter and thinner than other safety limit switches these are sized to fit tight spaces. 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. The switch makes sure the furnace is operating safely and at its desired settings.

They are often used in pump and hydraulic power applications. They can be wired normally open no or normally closed nc. However they are commonly found on heat pumps.
