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.

This pressure will be based on specifications for maximum pressure for the refrigeration systems high side and the type of refrigerant used. Shorter and thinner than other safety limit switches these are sized to fit tight spaces. The switch makes sure the furnace is operating safely and at its desired settings. Compact safety limit switches.

High and low pressure switches may be installed on the refrigerant tubing of some air conditioning systems. Long distance light beam. Rated ip69k these switches can withstand high pressure high temperature washdowns and temporary submersion. Standardized limit switches are industrial control components manufactured with a variety of operator types including lever roller plunger and whisker type.

Switches are single pole double throw spdt so they switch one circuit on or off. The key is to protect the compressor from extremely high pressures that could damage. They are often used in pump and hydraulic power applications. The high side if equipped with a high pressure switch should be set according to the manufacturer s recommendation.

Designed for high pressure applications these switches electrically activate automated controls or alarms when a set pressure is reached. 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. The high temperature limit switch is an important device used in forced air furnaces powered by gas or heating oil.
