With the continuous advancement of technology, sensor technology is also developing, and temperature sensor ntc is widely used in various fields. Sensor manufacturers have strict internal quality control and procedures, and it is reasonable to have errors, so sometimes there will be some problems or failures when the temperature sensor is applied.
Having a certain temperature sensor ntc fault resolution common sense is also one of the necessary skills. Below we will share some common faults and solutions in the application of temperature sensors.
First, there is no change in the output of the transmitter when the temperature of the measured medium increases or decreases. This is generally a problem with the temperature sensor ntc seal. It may be that the temperature sensor is not sealed properly or the sensor is accidentally welded with a small hole during welding. This situation generally requires replacement of the sensor housing to resolve.
Second, the output signal is unstable, which is generally the cause of the temperature source. The temperature source is an unstable temperature. If the instrument display is unstable, it is the reason that the instrument's anti-interference ability is not strong.
Third, the output error of the transmitter is large, and there are many reasons for this situation. If the resistance wire of the selected temperature sensor is wrong, it will easily lead to a range error. There may also be a case where the sensor is not calibrated when it leaves the factory.
It is rare for temperature sensor ntc to malfunction. As long as careful inspection is carried out at the time of shipment, these conditions can be avoided, so the temperature sensor should be inspected at the time of shipment. Customers can also ask the sensor manufacturer to request factory inspection Report for reference.
