Where can digital pressure switches be used?

Now in industrial production is also often used to it, digital pressure switch in here is not that kind of pressure gauge switch, it is mainly used to detect, display, alarm and control signal output, can well ensure system normal operation, through the high-speed data acquisition and data processing. The pressure switch is now widely used in chemical, mechanical, hydrological and electric power and so on the measurement of gas and pressure in the automatic system, because of its very flexible adjustment, simple and convenient installation, so it can be a good substitute for many practical liquid level switch places.

The principle of the switch

When the pressure in the medium is higher or lower than the rated safety pressure, the disc in the inductor moves instantly, and the switch joint is connected or disconnected by connecting the guide rod. when the pressure falls to or rises to the rated recovery value, the disc resets instantly, the switch automatically resets, or simply, when the measured pressure exceeds the rated value, the free end of the elastic element produces displacement. Directly or after comparison, push the switch element and change the on-off state of the switch element to achieve the purpose of controlling the measured pressure. The elastic elements used in the digital pressure switch are single-loop spring tube, diaphragm, diaphragm, bellows and so on. The switch elements are magnetic switch, mercury switch, fretting switch and so on.

 

Where can digital pressure switches be used?

Now the digital pressure switch is often used in industrial production, which is mainly used to detect, display, alarm and control signal output, which can ensure the normal operation of the system, through high-speed acquisition and data processing. Digital pressure switch is also widely used in the automatic system of measuring gas and pressure in the chemical industry, machinery, hydrology, electric power and so on, because it is very flexible to adjust and easy to install, so it can be a good substitute for many practical liquid level switches. The switch can read the pressure data online, and before the switch is officially put into use, the user needs to check all the parts of the digital pressure switch to see if it is preserved well enough. Only when the switch is in good condition can it be formally put into use, the digital display switch can be set, and each parameter needs to be set in the limit range of the digital display pressure switch. Must not carry on the overload work, this will greatly reduce the service life of the digital display pressure switch.


 

Matters needing attention

Digital display pressure switch in the process of measurement, the final need for a special person to observe, so as to avoid emergencies in the process of its operation. After each use of the digital display pressure switch, it is necessary to clean up the internal components so as to prevent the tested medium from remaining in it. In order to protect the display screen of the digital pressure switch, it needs to be wiped regularly to prevent the invasion of impurities such as dust. The regular performance testing of the digital display pressure switch can well prevent the gradual aging of its components caused by the cumulative application, which will also have a certain impact on the process of measurement.

 

Digital pressure switch is a new generation of pressure switch developed on the basis of the early traditional analog pointer barometer and high-precision digital sensing technology. It is used for the detection and control of air pressure in the field of pneumatic control. Guangdong NNT Pneumatic Technology Co., Ltd. also has these products, welcome to buy them.
