What is temperature compensation

2018-04-25 16:00:52

Temperature compensation is superheated steam and saturated steam are compensated by table lookup and linear interpolation. In the case of constant ΔP or If, the flow of the fluid is square root or proportional to the density of the fluid, and the density of most fluids (especially gases) will change with the change of working conditions, so the density of the fluid should be compensated by temperature and pressure. The so-called temperature compensation is to make the reference temperature of the free end of the temperature sensor more appropriate. Most temperature sensors need temperature compensation, and the commonly used temperature compensation method is bridge compensation. Extended data: In some electronic products, some positive temperature coefficient and negative temperature coefficient of electronic components will be used, take resistance as an example, positive temperature coefficient with the increase of temperature, resistance value increases, negative temperature coefficient is the opposite. In the application, to make a sensor, if you use a single temperature coefficient element, the error will be relatively large, if you use a positive and negative temperature coefficient element combined, just positive and negative phase balance, the error will be relatively small.
