As the temperature rises, the resistance of the ntc thermistor gradually shows a material with a smaller correlation index. Generally speaking, this material can use a variety of different metal elements, two or more tha
Read MoreThe ntc thermistor has an important protective effect in the circuit, which makes the current more stable and effectively avoids the situation of large current fluctuations. The circuit safety protection has important fu
Read MoreThis is because the ntc thermistor can play an important role in the current, not only can protect the circuit, but also can be used to detect temperature, so it has been widely used. For any ntc thermistor, it has a uni
Read MoreThermistors include positive temperature coefficient (PTC) and negative temperature coefficient (NTC) thermistors. The main characteristics of thermistor are as follows: ① high sensitivity, and its temperature coeffici
Read MoreThe capacitive liquid level meter measures the liquid level by measuring the change of capacitance. A metal rod is inserted into the liquid container, the metal rod is used as one pole of the capacitor, and the container
