Funcionamiento del Sistemas
Motor Temperature Sensor
Measure the temperature of engine / engine oil to 200 ° C.
Functioning
Thermistors are semiconductor whose resistance changes with temperature. The resistivity decreases with an increase in engine
temperature and having a negative temperature coefficient (NTC) and vice versa. The characteristics of the engine temperature
are plotted. (The values ​ ​ d o
not match exactly, it's just a representation for better understanding).
This NTC thermistor is used to measure engine temperature in the engine management system (EMS)

Building
The main method is temperature measurement by a thermistor. The thermistor is
made semi conductive material such as cobalt or nickel oxides and which is
encapsulated in a brass tube to protect mechanically.
