Low Pressure High Pressure Switch

The low pressure switch monitors the refrigeration system for a loss of refrigerant.

Low pressure high pressure switch.

Medium pressure me series. They are often used in pump and hydraulic power applications. A high pressure switch hps and a low pressure switch lps are protective devices for the compressor and refrigeration circuit. The pressure switch comes is to be installed imidiately downstream of the mainline source valve per nfpa 99 and are to be wired as normally closed on all circuts.

Low pressure lp and le series. When a refrigeration system operates at lower than normal pressures the system can freeze up with the freezing beginning at the evaporator coil. Low pressure switch open on pressure drop closes on pressure rise. 3 9 out of 5 stars 5.

Kp pressure switches are for use in refrigeration and air conditioning systems to give protection against excessively low suction pressure or excessively high discharge pressure. 4 3 out of 5 stars 26. As pressure rises further the high pressure switch will close energizing the coil of relay cr. As pressure falls the high switch will break but this has no effect on the switching circuit.

High pressure hp and he series. 24v 120v 240vac 50 60hz 6rla 36lra. Pressure switches are widely used in industry to automatically supervise and control systems that use pressurized fluids. Get it as soon as fri sep 11.

Designed for high pressure applications these switches electrically activate automated controls or alarms when a set pressure is reached. The honeywell pressure switch portfolio consists of. The switches are also used for starting and stopping refrigeration compressors and fans on air cooled condensers kp pressure switches are available in ip 30 and ip 44. The high pressure switch monitors the system for an inoperative outdoor motor and or a dirty restricted condenser outdoor coil.

These pressure switches are durable reliable electromechanical gauge pressure on off switches that are available with either single pole single throw spst normally open or normally closed circuitry or single pole double throw spdt circuitry. The relay locks in electrically through contacts cr1 and the low pressure switch. They can be wired normally open no or normally closed nc. High pressure switch open on pressure rise closes on pressure drop.

Free shipping on your first order shipped by amazon. Standard high low pressure switch are for 0 100 psi the standard setting is 40 60 psi. Switches are single pole double throw spdt so they switch one circuit on or off. Four seasons 20916 high cut out pressure switch.

1 4 female sae mounting. The switch may be designed to make contact either on pressure rise or on pressure fall. A pressure switch is a form of switch that operates an electrical contact when a certain set fluid pressure has been reached on its input. Low refrigeration pressure switches the low pressure switch is typically an automatic reset switch that will reset itself when the pressure on the low pressure side of the refrigeration systems returns to normal or above the setting on the switch.
