Product Description

The PSN type micro differential pressure controller uses a diaphragm-type pressure sensing element, featuring symmetrical high and low-pressure chambers. It offers a wide measurement range, excellent stability, and is widely used in industries such as metallurgy, stone, oil, chemical, machinery, shipbuilding, light industry, and power. It is also applied in pneumatic and hydraulic filtration equipment for differential pressure monitoring, alarms, interlock protection, and two-position automatic control.

    select and use
1. The control pressure setting value should be selected in the range of 20%~80% of the adjustment range.
2. When the medium temperature is too high, a spiral cooling tube can be added in front of the pressure interface (please specify when ordering, our company can supply it).
3. The instrument is easy to install, and it can work normally when installed on the wall or pipe. If installed outdoors, necessary protection should be given.
4. The controller must be repaired by professionals, and the rubber sealing pad should be replaced in time after aging.
5. If there is special selection or installation, please indicate and provide relevant technical requirements when ordering.
