Pressure switchIt has two main functions. One is to maintain system pressure or reservoir level. The other is to protect equipment from damage or inefficient operation.

Pump system:

This is probably the most common use of pressure switches. The pump uses a pressure switch to cut off the power to the motor and drive the pump under low water level or low line pressure. When the set pressure is reached, the power supply is cut off.

Compressed air system:

This is similar to a water pump system. When low pressure is detected, the pressure switch is used to cut off the power to the compressor motor. This maintains the pressure of the compressed air system.

Pneumatic and hydraulic systems:

These are control systems that use pneumatic and hydraulic actuators. Pumps and compressors maintain reservoir pressure and level through pressure switches.

Air conditioning and refrigeration:

In a refrigeration system, the thermostat provides a control feedback signal. However, if there is a problem with the system, the thermostat will only sense the temperature of the space being cooled, not the state of the device. The pressure switch is used as a protective device to trip the compressor motor under overpressure. Another use of pressure switches in refrigeration systems is low pressure protection, indicating possible refrigerant leaks.

Furnace and boiler systems:

Pressure switches in furnaces or boilers are used as safety interlocks to prevent the igniter from operating in the event of a problem with the ventilation system. This prevents the combustion chamber from running, which can lead to incomplete combustion.

Filtration and screening equipment:

The differential pressure switch is used to measure or monitor the pressure drop between the filter and the screen. The pressure switch triggers an alarm or notification to indicate that the filter is blocked or clogged and needs to be maintained, cleaned or replaced.

A pressure switch is a switch activated by the pressure of a process fluid when it reaches a specific threshold or set point. Pressure switches can have bourdon tubes, pistons, diaphragms, or membranes that move or deform depending on the amount of pressure applied by the system.

There are two main types of pressure switches: mechanical pressure switches and electronic pressure switches. The mechanical pressure switch has a mechanical pressure detecting part which deforms according to the fluid pressure.

● Electronic pressure switches are solid-state switches that do not require a pressure sensing element to operate the switch. They operate indirectly by using other properties, such as resistors and capacitors.

● The pressure switch has two main functions. One is to maintain system pressure or reservoir level. The other is to protect equipment from damage or inefficient operation.
