The sensor of a tensile testing machine is a detection device that can sense the detected information and transform the detected information into electrical signals or other required forms of information output according to certain rules, meeting the requirements of information transmission, processing, storage, display, recording, and control. It is a device or device that can sense the specified measured information and generate usable signals according to certain rules, Usually composed of sensitive components and conversion components. The classification of sensors for tensile testing generally includes temperature sensors, ink sensors, speed sensors, and pressure sensors. Below is a detailed description of each sensor.
1. Ensure that the clearance between the bottom of the speed sensor and the top of the engine teeth is 0.8 to 1.0mm, otherwise it may cause inaccurate indication. The correct installation method is to first screw the sensor to the bottom, that is, the bottom of the sensor touches the top of the engine flying gear, then turn it counterclockwise by two-thirds of a turn, and then tighten it with a back nut.
2. The grounding of the temperature sensor sensor should be reliable, and the wire connection of the sensor should not be short circuited. The thermistor of the dynamic magnetic water temperature gauge sensor will gradually decrease as the temperature increases.
3. The movement of the float inside the fuel tank of the fuel sensor should be flexible, otherwise the indication may be inaccurate due to the interference between the float and the fuel tank partition. The grounding of the fuel sensor should be reliable. The resistance of the variable resistance sensor of the dynamic magnetic fuel gauge will increase as the oil level inside the tank rises.
4. The variable resistance value of the pressure sensor dynamic magnetic pressure gauge increases with the increase of pressure. When installing the pressure sensor, it is not allowed to directly screw the casing. If the sensor has an alarm, the sensor wire and alarm wire cannot be connected in reverse.
