How to Use Intelligent Digital Differential Pressure Switch

Intelligent digital display differential pressure switch is a new design kind of sensor equipment with high precision and stability, which can be used in many fields.

The intelligent digital display differential pressure switch adopts the pressure sensor with high precision and stable performance, and through the special CPU modular signal processing technology, realizes the detection, display, alarm and control signal output of the medium pressure signal. The intelligent digital display differential pressure meter can be widely used in petroleum, chemical industry, automatic production line, pressure vessels, engineering machinery, hydraulic and pneumatic systems, water supply and other fields to measure and control the pressure of various gases and liquids, is an ideal intelligent measuring and controlling instrument in the industrial field.

1. Intelligent digital display differential pressure switch belongs to the field of precision instruments and meters, so it must be handled gently in the process of transportation, storage, installation and use, it can not be hard hit, storage place should also be a ventilated dry place.

2. Make sure that the position of the internal components of the intelligent digital display differential pressure switch cannot be changed, otherwise the measurement accuracy will be affected. When installing digital display differential pressure switch, make sure according to the installation steps in the instructions for operation, the parameters are set within the rated allowable range.

3. To prevent damage of differential pressure switch, user should open and close the valve slowly. when measuring gas medium, in order to ensure the stability of the system equipment work, if the device of pressure fluctuation is bigger, it should be aimed at that intelligent pressure switch is equipped with gas damper, to reduce the influence of pressure impact of intelligent pressure switch. In addition, if the surrounding environment has a negative impact on the intelligent differential pressure switch, it should be appropriate to take different measures to treat with according to the environment, such as vibration environment, high and low temperature environment.

4. In the long-term use of the intelligent digital display differential pressure switch, in order to avoid frequent maintenance, the measured medium must meet the measurement requirements of the intelligent pressure switch, no damage to the intelligent pressure switch medium, otherwise it will not only affect the measurement accuracy, but also cause damage to the pressure switch. After each use of the pressure switch, it is necessary to have a special operator to clean, check, maintenance, to develop a good maintenance habit is an important prerequisite to ensure the service life of the intelligent pressure switch.

Notes for differential pressure switch

Differential pressure switch is widely used in high and low pressure protection control scenarios, steam conditions and power stations; Accumulators, receivers, flash tanks, separators, scrubbers, refinery units, etc. It is also suitable for high and low pressure control of various equipment and tools. However, in the selection of pressure switch, the following points should be noted:

1. Whether explosion proof is needed,

2. Number of contacts: one SPDT switch (one output) or two SPDT contacts (two outputs).

3. The pressure range of the pressure switch should be selected according to the corresponding environment.
