Sensors are very important electronic components used in various types of mechanical equipment and household appliances. Hall sensors and temperature sensors are currently the most widely used sensors. Next, the Sensor Expert Network will take you to understand the purposes of temperature sensors and how to determine temperature sensor faults?
Temperature sensors play a very important role in ensuring product quality, improving production efficiency, saving energy, ensuring production safety, and promoting the development of the national economy. A temperature sensor indirectly measures an object by changing its characteristics with temperature changes. The characteristics of many materials and components vary with temperature, so there are quite a few materials that can be used as temperature sensors. The physical parameters of temperature sensors that change with temperature include expansion, resistance, capacitance, electromotive force, magnetic properties, frequency, optical properties, and thermal noise. Sensor Expert Network believes that with the development of production, new temperature sensors will continue to emerge. Due to the extremely wide range of temperature measurement in industrial and agricultural production, from a few hundred degrees below zero to several thousand degrees above zero, temperature sensors made of various materials can only be used within a certain temperature range.
How to determine temperature sensor failure
1. Use a tester to check for any malfunctions.
2. If there is a fault code, detect the sensor related circuit or the sensor itself according to the meaning of the fault code.
3. Use a detector to check the data flow. The read intake pressure value should be consistent with the current manifold pressure, and the read intake temperature should be consistent with the temperature of the gas in the current intake manifold. If the value read differs significantly from the current pressure and temperature, remove the intake pressure and temperature sensor and check if the sealing ring of the sensor is damaged. Check if the leakage probe is damaged or blocked by dirt.
Once the temperature sensor is damaged, it will affect the overall operation of the equipment, and many people want to know how to determine the fault of the temperature sensor. You can use a tester and fault codes to determine faults.
