Make an Arduino Temperature Sensor (Thermistor Tutorial) The thermistor I used in this article is a NTC thermistor, so if you have a PTC thermistor, it could cause the temperature changes to become opposite from what you would expect. I don’t have a PTC thermsitor to experiment with, so I’m not sure what the code would look like for a PTC thermistor. Reply Thermistors and NTC Thermistors Basic Electronics Tutorials The Thermistor is a solid state temperature sensing device which acts a bit like an electrical resistor but is temperature sensitive. Thermistors can be used to produce an analogue output voltage with variations in ambient temperature and as such can be referred to as a transducer. The basics of Built in Motor Protection for Beginners Thermistor PTC. The thermistor temperature sensing system consists of positive temperature coefficient sensors (PTC) embedded in series of three – one between each phase – and a matched solid state electronic switch in an enclosed control module. A set of sensors consists of three sensors, one per phase. Thermistor motor protection relay CM MSS The thermistor motor protection relay CM MSS.51 is used to monitor the temperature of motors or generators equipped with PTC resistor sensors type A. The sensors are built in into the motor windings, measuring the motor heating. In case of an increase of the temperature in the motor, the resistance of the PTC sensors will increase as well. Measuring Temperature with an NTC Thermistor Projects Measuring Temperature with an NTC Thermistor August 15, 2016 by Joseph Corleto ... which means as the temperature increases, the resistance increases. However, PTC thermistors have a sort of tipping point and greatly change the resistance at some temperature. This makes the PTC thermistor a little harder to interface with. ... Wiring It Up. I ...
