According constitute the basic sensor: a basic single conversion device. Combined Sensor: The sensor consists of a combination of different single converting means constituted. Applied sensor: Sensor is a sensor or a combination of the basic sensor in combination with other agencies constituted. Press the action in the form of press action can be divided into active and passive sensors. Active sensors have acting and reaction type, such sensors can send certain measured object detection signal can be detected in the tested object change detection signal arising from or produced by the detection signal in the object to be measured in some effect form signal. Called acting, the detection signal generated in response to the formation of a reaction-type detection method is called the detection signal changes in the way. Radar and radio frequency range detector is acting instance, while the photoacoustic effect analysis means is counter-example of the laser analyzer. Passive sensor only receives signals measured object itself, such as infrared radiation thermometer, infrared imaging devices. Pressure sensor lead is the most common industrial practice a sensor Tianjin quality filter sensors, which are 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, piping, etc. Many industries. Ultrasonic distance measuring ultrasonic distance sensor measuring ultrasonic echo ranging principle, the use of accurate time difference measurement technology, the distance between the sensor and the target, using small angle sensor Tianjin prime filters, small blind ultrasonic sensors, a measurement accuracy , non-contact, high-quality filter water Tianjin sensors, anti-corrosion, low cost, etc., may be in liquid, level detection, the unique level of Tianjin high-quality filter sensors, level detection method can guarantee the liquid face foam or large rock, the case is not easy to detect the echo of a stable output, application industry: level, level, level detection, industrial process control.
