Do you know the application of sensors?
1.Resistance sensor
The basic principle of a resistive sensor is to convert the measured change into a change in the resistance value of the sensing element, and then convert it into an electrical signal output through a conversion circuit. Applications: 1. Strain resistance sensors, used to measure tensile and compressive stress, and other physical quantities based on them; thermistor sensors, used to measure temperature; sliding-arm resistance sensors, used to measure geometrical positions (angles, displacements); Thermistor sensor is used to measure the magnetic field. ; Photoresistance sensor to measure the intensity of light; hygroscopic medium resistance sensor to measure humidity; liquid resistivity sensor to measure water-soluble ion concentration.
2. Potential type sensor
The inductive sensor has the outstanding advantages of simple structure, fast dynamic response, and easy to achieve non-contact measurement. Interface level measurement is currently widely used in metallurgy, petroleum, chemical, coal, cement, food and other industries.
3. Inductive sensor
Detects the attenuation of the distance. The glide is iron, which is suitable for the detection of inductive sensors; while the size of the measured part of glide is slightly smaller than the size of the standard test object (the size of the standard test object is 3 times the rated detection distance. In this application, the standard size should be 120 * 120mm ), Then there will be a certain attenuation; anti-interference ability on the spot. This is a problem that cannot be ignored. Ordinary inductive sensors are easily interfered by motors or frequency converters. Many technicians only choose corresponding strong anti-electromagnetic interference sensors for applications in the vicinity. However, in the automobile manufacturing workshop, the factory building is large, and on-site technicians are accustomed to use walkie-talkies to communicate, especially when they walk on the walkie-talkie, they will inadvertently approach the sensor, which will cause short-term failure; installation. With the popularization of inductive sensors, not only has the electrical performance improved, but its mechanical design has become more and more user-friendly. To the greatest extent possible to achieve user-friendly installation. Reduced the preparation of multiple similar products and reduced the time for installation and maintenance; the guarantee of stable operation. In the use of depots, it is necessary to prevent any erosion of oil and dust. In addition, when the glide passes through the track, the vibration is long-lasting, and the excellent vibration resistance also plays a very important role.
Piezoelectric micro-displacement, shaking table, electron microscope fine-tuning, astronomical telescope lens fine-tuning, precision micro-displacement measurement, measuring liquid level, humidity, and material composition.
5.Eddy current sensor
Eddy current sensors can be used to measure vibration, displacement, thickness, revolutions, temperature, hardness and other parameters, and can also perform non-destructive testing. The application of KD2306 eddy current sensor in displacement can be used to detect the axial displacement and differential expansion of rotating machines.
6. Semiconductor sensor
The main application fields of semiconductor sensors are industrial automation, telemetry, industrial robots, home appliances, environmental pollution monitoring, medical care, medical engineering and biological engineering. Semiconductor sensors are classified into physical sensitive, chemically sensitive and biologically sensitive semiconductor sensors according to the input information.
7. Resonant sensor
Resonant sensors have the advantages of small size, light weight, compact structure, high resolution, high accuracy, and easy data transmission, processing and storage. It is mainly used to measure pressure, but also to measure torque, density, acceleration and temperature.
8.Magnetoelectric sensor
Magnetoelectric sensors are mainly used for vibration measurement. Among them, the inertial sensor does not need a stationary base as a reference, and it is directly mounted on the vibrating body for measurement, so it has been widely used in ground vibration measurement and airborne vibration monitoring systems. Commonly used ground vibration sensors include moving iron type vibration sensors, ring type vibration speed sensors, and the like.
9. Electrochemical sensor
Application of chemical sensors in environmental and sanitary monitoring: In environmental and sanitary monitoring, it is often used in wet-bulb temperature hygrometer, hand wet thermometer and ventilation wet thermometer to measure air humidity. Application of electrochemical biosensors in early diagnosis of diseases: DNA electrochemical biosensors are a new type of biosensors that have been hotly researched in the world in recent years. They have the characteristics of strong specificity, high sensitivity, fast detection, simple and economical. Early diagnosis of major diseases such as tumors is of great significance.
