Pressure sensors are the most commonly used industrial practice a sensor, which is widely used in various industrial automation environment, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil, electricity, shipbuilding, machine tools many industry pipelines, following a brief introduction of some commonly used sensor principle and its application. Pressure sensors are the most widely used kind of sensor. Conventional pressure sensor to the mechanical structure of the main type of device, indicating a deformation of the elastic pressure member, but this structure size, quality, weight, do not provide an electrical output. With the development of semiconductor technology car booster pump pressure sensors, semiconductor pressure sensor also emerged. It features small size, light weight, high accuracy, good temperature characteristics. Especially with the development of MEMS technology, semiconductor sensors toward miniaturization, and its small power consumption, high reliability. Usually when the car in the selection of pressure sensors, need to have knowledge of the following: 1, brand Myth: Many times we believe that domestic products are difficult to use, or even can not be used. 2, precision errors: everyone in the car when selecting product price pressure sensors, precision always thought was the most important; in fact, from a certain point of view: the stability of the product is more important than accuracy, precision choice should be based on the high stability on the basis of. 3, the pursuit of cheap: inexpensive it is everyone wants to see; but in fact, high-quality products to determine its price will be relatively higher. 4. Select the appropriate range, precision fit, proper installation, proper output.
