Fields of Application of Pressure Sensors

1. The pressure sensor is applied to the hydraulic system

In the hydraulic system, the pressure sensor is mainly used to complete the closed-loop control of the force. When the control spool moves suddenly, a peak pressure several times the working pressure of the system will be formed in a very short period of time. In typical mobile and industrial hydraulics, any pressure sensor can quickly be destroyed if not designed with such extreme conditions in mind. It is necessary to use a shock-resistant pressure sensor. There are two main methods for the pressure sensor to achieve shock resistance. One is to change the strain gauge chip, and the other is to connect an external coil. Generally, the first method is used in the hydraulic system, mainly because Easy to install. Another reason is that the pressure sensor is subject to constant pressure pulsations from the hydraulic pump.

2. Pressure sensors are used in safety control systems

Pressure sensors are often used in safety control systems, mainly targeting the safety management system of the air compressor itself. There are many sensor applications in the field of safety control. As a very common sensor, it is not surprising that pressure sensors are used in safety control systems.

The application in the field of safety control is generally considered from the aspects of performance, from the consideration of price, and from the safety and convenience of actual operation. Practice has proved that the effect of selecting a pressure sensor is very good. The pressure sensor uses the processing technology of mechanical equipment to install some components and signal conditioners on a small chip. So small size is also one of its advantages, in addition, cheap is another big advantage of it. To a certain extent, it can improve the accuracy of system testing. In the safety control system, the pressure brought by the compressor is controlled to a certain extent by installing a pressure sensor in the pipeline equipment at the air outlet. This is a certain protection measure and a very effective control system. When the compressor starts normally, if the pressure value does not reach the upper limit, the controller will open the air inlet and adjust the equipment to reach the maximum power.

3. The pressure sensor is applied to the injection mold

Compressive load cells play an important role in injection molds. The compressive load cell can be installed in the nozzle of the injection molding machine, the hot runner system, the cold runner system and the cavity of the mold. Plastic pressure somewhere between the cavities.

4. Pressure sensors are used to monitor mine pressure

Sensor technology is one of the key technologies for mine pressure monitoring. On the one hand, various existing sensors should be correctly applied to serve the mining industry; on the other hand, as a sensor manufacturer, new pressure sensors should be developed and developed to adapt to more mining industry applications. There are many kinds of pressure sensors, and based on the special environment of mine pressure monitoring, mine pressure sensors mainly include: vibrating wire pressure sensor, semiconductor piezoresistive pressure sensor, metal strain gauge pressure sensor, differential transformer pressure sensor, etc. These sensors have a wide range of applications in the mining industry, and the choice of which sensor to use depends on the specific mining environment.

5. Pressure sensors used to promote sleep

The compressive load cell itself cannot promote sleep, but the compressive load cell is placed under the mattress. Due to the high sensitivity of the compressive load cell, when a person turns over, heartbeat, breathing and other related actions, the sensor will analyze this series of information to infer the sleeping person. What is the state of sleep, and then through the analysis of the sensor, collect the signal of the sensor to get the sleep data such as heartbeat and breathing rhythm, and finally process all the data into a piece of music, of course, you can compress your sleep one night into a song A few minutes of music.

6. Pressure sensors are used in compressors, air conditioning and refrigeration equipment

Pressure sensors are often used in air compressors and air-conditioning refrigeration equipment. These sensor products are small in size, easy to install, and the pressure guide port generally adopts a special valve pin design.
