Low Pressure Switch Water Heater SPST-NO 24VDC

W11 Low Pressure Switch Water Heater Function

The low pressure switch when the pressure in the system is higher or lower than the set pressure, the pressure sensor in the controller acts immediately so that the contacts in the controller are connected or disconnected, and the equipment stops working at this time, When the pressure in the system returns to the set pressure range of the equipment, the pressure sensor in the controller is immediately reset, so that the contacts in the controller are connected or disconnected, and the equipment works normally.Low pressure switch water heaters are also used on wind pressure switches and water level switches.

Low-Pressure Switch Water Heaterthe pressure in the system is higher or lower than the rated safety pressure, the sensor disc instantaneous movement, through the connection guide rod to promote the switch connector connected or disconnected, when the pressure drops to or up the rated recovery value, the disc instantaneous reset, switch automatic reset, or simply when the measured pressure exceeds the rated value, the free end of the elastic element displacement,  Push the switch element directly or after comparison to change the on-off state of the switch element to achieve the purpose of controlling the measured pressure. Low Pressure Switch the elastic components of the pressure switch include a single coil spring tube, diaphragm, diaphragm box, and bellows.

Water Pressure Switching Principle Of  Water Heater

The water pressure switch principle of a water heater refers to the cold water entering the water heater, flowing through the water gas linkage valve body under the action of a certain pressure difference of flowing water, promoting the water gas linkage valve, and at the same time promotes the DC power microswitch to connect the power and start the pulse igniter, at the same time opens the gas transmission electromagnetic valve, through the pulse igniter continues to automatically ignite again. Until the ignition is successfully into the normal working state.

This process is about 5-10 seconds continuous time, when the gas water heater is in the working process or ignition process of insufficient water or water pressure, lack of electricity, lack of gas, hot water temperature is a too high accidental blowout, and another fault phenomenon, pulse igniter will detect the sensor needle feedback signal, automatically cut off the power supply, The gas transmission solenoid valve immediately returns to the original normally closed valve state in case of lack of power supply.

Water Pressure Switch Water Heater Main Parameters

1.  Water pressure switches small and exquisite appearance, are easy installation and use wiring, and interface type can be produced according to user requirements.

2. the switch electrical contact adopts components imported from Japan, long working life (more than 150,000 times), single knife single throw, single knife double throw contact types for users to choose from.

3. all stainless steel pressure inductors imported components from the United States, reliable work, excellent performance, high-pressure accuracy, long working life (more than 150,000 times), use Italy’s advanced welding process equipment, the sealing performance is superior, no leakage.

4. the working pressure can be manufactured according to the requirements of users (30inHgv ~ 800PSI/-0.1 ~ 5.5Mpa).

Water Pressure Control Switch Joint

Because the different applications will have different installed interface types.  Please see the Pictures as following below or contact us.
