Common types of pressure switches
Miniature Pressure Switch
Miniature pressure switch PC-100 has a long working life (more than 100,000 times) and excellent shock resistance. It can be used to monitor liquid or gas pressure.
Manual Reset Pressure Switch
Manual Reset Pressure Switch uses international advanced stainless steel pressure diaphragm with high accuracy. Small size, easy installation and use, high and low pressure integrated design. It can simultaneously control the pressure of the high pressure end and the low pressure end of the system. Manual reset, suitable for semi-automatic operation occasions.
Stainless steel differential pressure switch
The differential pressure switch is made of stainless steel, which can be dirt-resistant, corrosion-resistant, clean and hygienic.
Differential pressure controller, also called differential pressure switch, differential pressure switch, differential pressure controller. It can also be used for cut-off protection of water pumps and filters. It can also be called: differential pressure type water flow switch, differential pressure type flow switch.
The adjustable differential pressure switch can provide a very wide range of adjustable differential pressure settings. It adopts stable micro switch and sensitive diaphragm to achieve the excellent advantages of high precision and low dead zone.
The adjustable differential pressure switch controller is developed for applications that are used in small quantities and have different requirements for differential pressure. It is usually used in engineering to detect the pressure difference of water filters, pumps, heat exchangers, chillers and coils.
When the water flow (pressure difference) in the system rises or falls to the set value. Output an alarm or cut-off function alarm to provide to the automatic control system. It can also be used to indicate the status of a pump or filter.
The differential pressure switch is composed of two diaphragm cavities. And the two into diaphragm and bellows type, And their performance characteristics are also differentsitive diaphragm. High pressure and low pressure enter the high pressure cavity and low pressure cavity of the differential pressure switch respectively. And the differential pressure felt deforms the pressure sensitive diaphragm. Through mechanical structures such as railing springs. Finally, the uppermost micro switch is activated to output the electrical signal.
Different pressure-sensitive components of differential pressure switches are divided into diaphragm and bellows type. And their performance characteristics are also different.
Differential pressure switches are composed of pressure-sensitive components, have different principles, and have different performances. The diaphragm type can be made into high static pressure and low differential pressure, while the bellows itself has low pressure resistance.
Stainless steel digital pressure switch
Stainless steel digital pressure switch, an economical digital pressure switch integrating pressure measurement, display and control. This series of pressure switches can be set with two normally open and normally closed alarm points, and can also achieve two high and low pressure controls. In addition, it has a key to zero, three display units switching and other functions.
The operation method of this pressure switch is simple and intuitive, just set the action point and hysteresis according to the manual, and the hysteresis of the two sets of relays can be set independently. According to the customer site, only one group of control can be used, or both groups can be used.

All products adopt food-grade 304 stainless steel joints and 304 stainless steel housings, providing different installation methods in axial and radial directions.
Weatherproof pressure switch
The degree of protection of the fully welded stainless steel shell is designed to reach IP67
General considerations for IP65 and IP67 protection levels:
In order to clarify the “secrets” of these two types of protection, this article will give a technical description: refer to IEC 60529. The first characteristic number specifies “prevention of solid foreign objects”. The second characteristic number specifies “prevention of water entry”.

In order to clarify the “secrets” of these two types of protection, this article will give a technical description: refer to IEC 60529. The first characteristic number specifies “prevention of solid foreign objects”. The second characteristic number specifies “prevention of water entry”.
Different protection levels can provide different types of protection:
“Dustproof” equipment (IP6x) to prevent “water jet” (IPx5) and “short immersion” (IPx7).
Not all immersion-proof instruments can withstand water jets, and vice versa, and not every instrument that is water-proof jets can be immersed.
In some applications this is a small but extremely important difference.
Stainless steel well pressure switch
A well water pressure switch helps to control a well pump system which helps provide water to a household or business. The pressure switch has a spring on the inside that’s connected to electrical contacts. As time goes on, the spring becomes weak and the electrical contacts wear out which can make it seem that your pump isn’t working quite right.
It is used with submersible well pumps and jet pumps.
Pressure switch for water
The water pressure switch, as the name implies, uses water pressure to control the switch.
When the water pressure switch is in use, a fixed value is generally set. That is to say, when the actual value is less than this fixed value or greater than this fixed value, it will give an alarm. And it moves to cause it to be connected to another connecting rod to switch Power on or off.
When the water pressure in the system reaches a fixed value, it returns to its original state, which acts as a switch.

Air pressure switch
The air pressure switch can be used to control the positive pressure, negative pressure and differential pressure of air, flue gas and other non-flammable gases. Especially in the case of differential pressure control, a small pressure difference can be monitored to achieve precise differential pressure control.
Air pressure switches mainly include two types of normally closed and normally open. The main feature is the use of inch pipe threaded quick coupling or copper pipe welding type installation structure. The installation procedure is flexible, convenient to use, and no special fixed installation is required.
The main application areas are the high and low pressure protection control of household, commercial and automobile refrigeration systems, steam conditions and power stations and other heavy industry areas.
