Working principle and adjustment of pressure controller

The working principle of the pressure controller: 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 at the same time outputs a detection signal or a control signal. The pressure controller generally uses a metal 316L diaphragm sensor, which can be used for neutral oil, gas medium and water. The setting value of the controller is adjustable, and the adjustment range -0.1~40MPa range is optional. The following is the adjustment method of the model D504/7DZ pressure controller: 1. Adjust the pressure limit to 1.5MPa (up switch value), and send a contact signal. The operation steps: 1. Open the cover and loosen the lock. 2. Turn the setting value adjustment screw clockwise to make the setting value change from large to small until the switch contact switches at 1.5MPa. 3. Tighten the locking device. 2. Adjust the lower limit of the pressure to 0.5MPa (lower switching value) to send a contact signal. The operation steps: 1. Open the cover and loosen the lock. 2. Turn the setting value adjustment screw counterclockwise to increase the setting value from small to large until the switch contact switches at 0.5MPa. 3. Tighten the locking device.
