Under the definition of national standards GB7665-87 sensor is: "can feel parts and provisions are measured according to certain rules (laws of mathematical functions) into the device or devices available sensor signals, usually made of sensitive components and conversion elements." Things Chinese schools and enterprises Union considers the existence and development of the sensor, so that the object had touch, taste and smell and other sensory sensors offer, make the object slowly becoming alive again. "" Sensor "is defined in New Webster Dictionary as:" to accept power from a system, usually in another form of the power system in the second device to the "pressure sensor lead is the most common industrial practice. a sensor, which is widely used in various industrial automation environment, involving a number of water conservancy and hydropower industry, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil, electricity, shipbuilding, machine tools, pipes, etc. ultrasonic distance measurement ultrasonic distance measuring sensor using ultrasonic echo ranging principle, the use of accurate time difference measurement techniques, the distance between the sensor and the target, using small angle, the small blind ultrasonic sensors, with measurement accuracy, non-contact, waterproof, anti-corrosion, low cost, etc., can be at what level sensor is, level detection, the unique level, level detection method can ensure there is a bubble in the liquid or large rock sensor suppliers, the situation is not easy to detect the echo Under a stable output, Industry: Level, level, level detection, industrial process control, sensor production | Xinfeng (certified) | Anhui sensor provided by Xinxiang City Xinfeng Sensing Technology Co., Ltd.
