Pressure sensor applications

Pressure sensor is a kind of common measuring instruments, with the use of flexible, measurement precision, stable performance, high reliability, etc. Is widely used in various industrial control environment. Pressure sensor main application fields of users understand? Engineering today is to introduce the specific pressure sensor application fields of what, hope you can help to you.

1, is applied to the hydraulic system

pressure sensor in the hydraulic system is mainly to complete the force closed-loop control. When the valve core moves suddenly, in a very short period of time will form a few times the system pressure peak pressure. In a typical mechanical and industrial hydraulic walking, if design without considering such extreme conditions, any pressure thermocouple sensors will soon be destroyed. Need to use the shock pressure of thermocouple sensors, pressure shock 2 main method to realize thermocouple sensor, one is in strain type chip, another method is the outer flange pipe, generally use the first method in the hydraulic system, mainly because of easy installation. In addition there is another reason is pressure thermocouple sensor to inherit from the pressure pulsation of hydraulic pump uninterrupted.

2. Applied in the safety control system

pressure sensor often applied in the safety control system, mainly aims at is the air compressor itself in the field of the safety management system. Application in the field of security control has a lot of thermocouple sensor, pressure thermocouple sensor as a very common thermocouple sensor, it is not surprising that applied in the safety control system.

in the field of security control applications generally consider from the aspects of performance, from price considerations, and in view of security and ease of operation, proves the effect of selective pressure thermocouple sensor is very good. Pressure thermocouple sensor using mechanical equipment processing technology will some elements and signal conditioning device installed on a small chip. So small volume is also one of the advantages of it, in addition to this, another big advantage is it cheaper. To a certain extent, it can improve the accuracy of the system test. In the safety control system, through in the outlet of the pipeline equipment installation pressure thermocouple sensors to control pressure of the compressor to a certain extent, this is some protection measures, is also a very effective control system. When the compressor normal boot, if the pressure value limit has not been achieved, the controller will open the air inlet through the adjustment to achieve maximum power equipment.

3. Applied in injection mould

pressure sensor plays an important role in the injection mold. Pressure thermocouple sensor can be installed in the nozzle of the injection molding machine, hot runner system, and mould cavity cold runner system, it can measure the plastics in injection molding, mold filling, pressure maintaining and cooling process from the injection molding machine nozzle to the cavity plastic pressure somewhere in between.

4. Applied to the monitoring of mine

pressure sensor technology, as one of the key technology of the mine pressure monitoring. On the one hand, we should correct application of the existing various thermocouple sensors to services for the mining industry; As a thermocouple sensor manufacturers, on the other hand, also the research and development of new pressure thermocouple sensors to adapt to more mining industry applications. Stress has a variety of thermocouple sensor, and based on the special environment of mine pressure monitoring, mine pressure thermocouple sensor mainly include: vibrating string type pressure thermocouple sensor, semiconductor piezoresistive pressure thermocouple sensor, metal strain type pressure thermocouple sensor, pressure differential transformer type thermocouple sensor, etc. The thermocouple sensor has widely used in mining industry, the specific use which kinds of thermocouple sensor and undertake choosing according to the specific mining environment.

5. Applied to promote sleep

pressure sensor itself unable to promote sleep, we just put pressure on thermocouple sensor mattresses, because the pressure thermocouple sensor has high sensitivity, when people turn, heart rate and breathing and related actions, thermocouple sensor will analyze this a series of information, to infer that sleep sleep in what a state, and then through the analysis of the thermocouple sensor, collection of thermocouple sensor signals to be sleep, such as heart rate and breathing rhythm, finally put all the data processing set a period of song, of course you sleep a night can be compressed into a few minutes of music.

6. Applied to the compressor, air conditioning cold equipment

pressure sensor is often used in air press, refrigeration and air conditioning equipment, this type of thermocouple sensor product appearance compact, easy installation, guide pressure generally USES special valve pin type design.
