مفتاح الضغط العالي أنثى 1/4 ″ SAE

• It is used to control high pressure. 
• Its connection size is ¼.
• Its shipping weight is 0.2.
• The type of connection is FFL.
• The country from where it is originated is China.
• The amount of its open pressure is 410.

A high-pressure switch is used for the measurement of discharge pressure by attaching it to the high side or discharge side of the system. When a specific pressure is put on the diaphragm of the system, this switch plays its role in protecting the system from extremely high or extremely low pressure. This switch provides this protection by opening and closing different contacts. This high-pressure switch is attached to the high side or discharge portion of the system so that it can feel and measure the discharge pressure.

صفات 

High-pressure switch 1/4 SAE is an extremely beneficial device that consists of many qualities within it. Some of them are going to be discussed below 

• When the pressure rises, a high-pressure switch comes into action and controls that high pressure within the range of economical prices to avoid any disaster. 
• This switch is an encapsulated switch that is non-adjustable. As the pressure of the system becomes high the high-pressure switch becomes automatically open to resist any damage. 
• It is such a useful switch that it can be used within HFC, HCFC, and CFC refrigerators. 
• This is such a type of switch that acts to control the operations with many appliances like low ambient condenser fan control.

تحديد 

• Every item is based on certain specifications that become its identity. Let’s discuss the specifications that are connected to the high-pressure switch.
• It is an encapsulated, non-adjustable, and high-pressure open on the rising of pressure.
• It has the capability of automatic resetting. 
• The type of its operator is snap-acting stainless steel that is sealed hermetically.
• The rate of operating pressure is 0 to 650 PSI.
• The medium of the pressure is fluid. 
• The configuration of contact is SPST.
• The type of connection is ¼ inch SAE female flare.
• Appliances where it can be used include a refrigerator, air conditioner, and heat pump system. 
• Approvals that are involved for this item are UL and CE.
• The rating of its voltage is 24/120/240 volt AC at 50/60 Hertz. 
• Its tolerance is of +/- 15PSI
• The lead length is of 18 inch 
• The size of the wire is 18 AWG.
• The temperature rate of this high-pressure switch is -30 to 80 degrees Celsius ( for ambient), and -50 to 120 degrees Celsius ( for fluid).
• It is also based on a valve core depressor.

المميزات:

Let’s discuss the benefits of this high-pressure switch:

• Its display is easily readable.
• It has pressure sensors that are of electronic style with an integrated LCD/LED screen that looks very prominent on the front side.
• Its operating principles are very simple.
• It is highly reliable.
• It is highly accurate so it seems to be trustworthy.

Disadvantage 

Along with advantages, every item is also based on certain disadvantages. Let’s discuss the Cons of pressure switch 

• In case of a malfunctioning pressure switch of AC, the compressor begins to work continuously. As a result, a lot of pressure will be generated within the system and become the cause of the generation of noise. Sometimes, the compressor produces the noise of a hummingbird. But sometimes, a clicking sound can also be heard.
• High-pressure switches cannot work within the environment of dirt and debris. Because debris will damage the diaphragm of the high-pressure switch, perforations will be created which will become the reason for the failure of the switch.

التطبيقات 

• The areas of usage of high-pressure switches are chemical, mechanical, and hydrological because they are capable of measuring and controlling liquid pressure with accuracy.
• This switch is used along with electrical switches. But it comes into action only when the pressure reaches up to a specified value.

This switch can also be used by industries being a protector as it has the capability of protecting against accidents.
