How does a digital pressure switch work?

It is one of the most commonly used fluid control components. We use them at home, in refrigerators, dishwashers and washing machines. Whenever we deal with gases or liquids, we almost always need to control the pressure. Our household appliances do not need high precision and high turnover. In contrast, pressure switches used in industrial machinery and systems must be rugged, reliable, accurate and have a high life cycle. Most of the time, we never consider the pressure switch. They just show up with machines or machine tools. In this kind of equipment, we rely on pressure switches to act as safety devices, alarms or control components in the system. But in most cases, we seldom consider this part when we buy it. How does the electronic pressure switch work?


Here is the content list:

l Digital pressure switches provide electronic switch output signals.

l Provide constant pressure readings and indicate whether the switch outputs are active or not.

l The purpose of controlling the measured pressure is achieved by changing the on-off state of the switch element.


Provide electronic switch output signals.

Digital pressure switchesprovide electronic switch output signals. They oftenalso produce an additional analogue output signal proportional to the pressure. Digital pressure switches are factory set to optimal switch points or are programmable on-site thanks to integrated displays and buttons. Their integrated programmable logic allows for the switch points and output signal to be tailored to the application. Among the many programmable functions of modern digital pressure switches are hysteresis, delay time, normally closed or normally open and window function.


Provide constant pressure readings and indicate whether the switch outputs are active or not.

They also provide constant pressure readings and indicate whether the switch outputs are active or not. IO-Link technology can also be used for remote programming via the signal cable.

Digital pressure switches are suitable for applications that demand stability, multiple switch points and flexibility of control such as for control and automated equipment. They are the desired choice for installations requiring flexible programming and adjustment, local indication display and extra analogue output signals.


The purpose of controlling the measured pressure is achieved by changing the on-off state of the switch element.

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 the connecting guide rod. when the pressure falls to or rises to the rated recovery value, the disc resets instantly, and the switch resets automatically, or simply, when the measured pressure exceeds the rated value, the free end of the elastic element produces displacement and pushes the switch element directly or after comparison. The on-off state of the switch element is changed 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.


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.
