Application of the principle of displacement sensors

Train rim geometry state parameters affect train running speed and smoothness , the safe operation of the train is very important. The traditional detection methods are more complex , usually with a special ruler with a cursor to be measured , the data read artificial measurement error caused by relatively large, can not be achieved simultaneously digitized test data management . With the development of China's railway , trains run faster, train rim state parameters precise and rapid overhaul and digital management become very important. Rim detector using modern sensor technology , single-chip processing systems and concise stable mechanical structure, convenient and accurate status on geometric parameters were measured in quick succession , to achieve a rim height, width, thickness and other parameters measuring rim digitization . Displacement sensor , also known as linear Car Temperature Sensor  , a metal sensor is a linear device , the sensor is the role of the various measured physical quantity conversion power. In the production process, the displacement measurement are generally divided into physical dimensions and mechanical displacement measuring two kinds. According to the measured variable transformation in different forms , displacement  Crankshaft Positioning Sensor  can be divided into analog and digital two. Displacement sensor in the sensor rise in recent years , especially in recent years capacitive displacement sensor favored , primarily , and it has good stability on . Capacitive displacement sensor capacitor plate , mostly metal , a backing plate , mostly inorganic materials such as air , glass, ceramics , quartz , etc. ; therefore at high temperature , low temperature strong magnetic radiation, long-term work , especially solution under high temperature and pressure detection problem. This makes the capacitive displacement sensor in these environments has an irreplaceable role. The sensor can be used with the control room of the second instrument or controller connected online , continuous , real-time detection of a variety of data and then directly display, remote control and alarm . Data storage , totalizer, transmission and control functions. Widely used in various injection molding machine . Capacitive displacement sensor is particularly suitable for small or slow changes of the measurement , in general the use of capacitive  Shaft Position Sensor detect more appropriate. Capacitive displacement sensors These properties will inevitably promote its wide range of applications increasingly month .
