How to calibrate the temperature transmitter? Temperature transmitters need to be calibrated, can be used after calibration, then the temperature transmitter should be how to calibrate it? The following is a small series of instrument and meter world network to give you a detailed introduction.
The calibration of the integrated temperature transmitter is actually very simple. Simply place the transmitter in an environment where the temperature can be accurately measured and the temperature is known, and record the transmitter's output for the same period of time as the known ambient temperature. Calculate the error of the transmitter.
The temperature transmitter can be classified into static and dynamic. Normally, we calibrate the temperature transmitter in a natural environment. It is always a slowly varying physical quantity.
How is the temperature transmitter calibrated? Therefore, the verification of the temperature transmitter in this state is static, but it can meet the actual needs of most transmitters. However, there are very few dynamic tests. General calibration uses lasers, so only special needs are required.
But in the calibration process, if you know the parameters of the temperature transmitter, then the calibration is also helpful, and the accuracy of the temperature transmitter calibrated by these parameters will be higher, making the measurement more accurate.
