NTC and PTC Sensor Testing and Use / Hindi

Thermistors or as we called sensor in Refrigeration and air conditioning unit. what are they? Let’s start by breaking down their name, which will give us a pretty clear indication of what they are and what they do: thermistor = thermal resistor. They are small electronic devices that react to a change in temperature (ambient included) by changing their resistance value. How do they do this? Well, there are two main types of thermistors: NTC and PTC. Each is made of a different material that reacts to temperature in a specific way. NTC - negative temperature coefficient PTC- positive temperature coefficient #ntc #ptc #thermistor #sensor #unique #technical #service
