Industrial equipment in the manufacturing process and overall performance testing can not be separated from a variety of mechanical and geometric quantities, some industrial equipment in the operation also often a variety of volume detection or monitoring, including displacement, speed, acceleration, force, torque , power, pressure, flow, temperature, hardness, density, humidity, specific gravity, viscosity, length, angle, shape, position, surface roughness, surface waveform, etc., these are all physical quantities. Actual production, life, and scientific experiments will also encounter chemical quantities, biomass (including medicine), and all of this, from the point of view of signal engineering, will require sensors to be converted into electrical signals (modern time can also Converted into optical signals, and then the signal transmission, processing, storage, display, control, from the information point of view, these signals together with sound and image information are the source of information, so sensors and detection instruments, measuring instruments are information The important part of the three parts of science and technology (information acquisition, information transmission, information processing).

In modern industrial equipment, pressure sensors and measuring instruments are an indispensable part of the reason, but also from the following two aspects, the traditional industrial equipment such as adding the necessary sensors, equipped with precision measurement components, its function And accuracy can be improved, user-friendly operation and maintenance, security level can also be increased, equipment can be added value; industrial equipment as part of the control of the automation system or as part of the automation system, must be able to and three parts of the automation system (detection, control, execution ) Compatible with or providing interfaces to integrate them into an organic whole, whether for stand-alone automation or as part of a large automation installation, has expanded the use of the industrial equipment. In summary, adding sensors and measuring instruments, measuring instruments or providing interfaces as industrial equipment itself is a necessary condition for the upgrading of traditional equipment.

A pressure sensor is a device that converts non-electrical energy into an electrical signal. In the case of analog electronic technology, the detection instrument generally includes a sensor, a detection point sampling device, an amplifier (for anti-interference processing and signal transmission), and of course, a power supply. And on-site display part (optional), the electrical signal is generally continuous, discrete two, in fact can also be divided into analog, digital, pulse, etc., analog signal transmission using a unified signal (4-20mADC, etc.). In the digitization process, the detection instrument changes greatly. After several stages, ASIC specific integrated circuits are used more recently, and sensors and microprocessors and network interfaces are encapsulated in one device to complete information acquisition, processing, transmission, storage, and the like. Features. Often referred to as a transmitter in the automated instrumentation, such as problem transmitters, pressure transmitters.

Because pressure sensors are used in all walks of life, coupled with the rapid development of household appliances, automobiles, and information industries in recent years, the demand for sensors has greatly increased. Therefore, the sensor manufacturing industry has developed rapidly, forming an independent industry, which has driven industrial equipment. Especially the development of semiconductor equipment manufacturing industry, so people need to pay special attention to the sensor industry. There are a wide variety of pressure sensor products, based on many scientific principles, intensive technologies, diversity, marginality, comprehensiveness and artistry, which require multidisciplinary and multi-technology cooperation.
