NTC thermistors are widely used in temperature measurement and control system. ATI provides a complete series of
NTC thermistors with high stability, high accuracy and a long service life, such as
There is a main theory of liquid level measurement for NTC thermistor. The gas and liquid are different media. If we can distinguish these two media, it’s easy to solve the problem of liquid level measurement when measuring them with NTC thermistors. It’s difficult to judge the media according to the measurement result when NTC thermistors measure temperature at zero power, i.e. non-natural state. When NTC thermistors are in self-thermal state and the temperatures of the media keeps the same, the dissipation factors of NTC thermistors are different. When NTC thermistors are in different media under the same electrical conditions, they will show different electrical performances. This is the basis of liquid level measurement.
