The HVAC Pressure Switch manufacturer tells you that the working principle of the pressure controller is that the working medium (oil, gas, water) directly acts on the metal diaphragm, and the deformation of the metal diaphragm reflects the pressure of the working medium, and outputs a detection signal or control signal.

The pressure controller is generally a metal 316L diaphragm sensor, which can be used for neutral oil, gas medium and water. The HVAC Pressure Switch manufacturer tells you that the set value of the controller can be adjusted, and the adjustment range can be selected from -0.1 ~ 40MPa.
How to adjust the pressure controller:
1. Open the cover and unscrew the lock.
2. Rotate the set value adjustment screw clockwise to make the set value from large to small until the switch contacts switch at 1.5MPa.
3. Tighten the lock.
Adjust the lower limit of pressure to 0.5MPa (lower switching value) to send a contact signal. The operation steps are as follows:
1. Open the cover and unscrew the lock.
2. Rotate the setting value adjusting screw counterclockwise to make the setting value change from small to large until the switch contacts switch at 0.5MPa.
3. The HVAC Pressure Switch manufacturer tells you to tighten the lock.
About the working principle and adjustment method of the force controller, the HVAC Pressure Switch manufacturer has introduced here, I hope it can help you.
