Thermistor Symbol Electrical Diagram. They are mostly used to draw a circuit diagram and are standardized internationally by the ieee standard ieee. Click the icon of basic electrical to open the library that includes all symbols for making electrical diagrams.
The sensors are transducers and electronic detectors activated by the energy delivered by a system and that in turn deliver another type of energy to another different systemthe transformed energy may be of physical chemical or biological origin. Here you can see the symbol of thermal resistor or thermistor. You should be able to recognise the circuit symbols for a thermistor and an ldr light dependent resistor and know how the.
As the switching type ptc thermistor gets heated initially the resistance starts to decrease up to a certain critical temperature after which as the heat is increased the resistance increases dramatically.

Thermistors symbols for use in electrical pneumatic and hydraulic schematic diagrams. But i think that the arrows describes how the thermistor behaves.
