The temperature sensor is a sensor, converting a temperature into an electrical signal. Available for air, coolant, fuel and oil temperature measurement.
In motor vehicles they are used to measure the temperature of the intake air in the range -40…130 °C.
NTC thermistors have a negative temperature coefficient, i. e. their conductivity increases with increasing temperature; their resistance decreases. The conductive element of the temperature sensor consists of semiconducting heavy metal oxides and oxidized mixed crystals pressed or sintered into wafers or beads with the aid of binding agents and provided with a protective casing. In combination with a suitable evaluation circuit, such resistors permit precise temperature determination. Depending on the housing design, the sensors are suitable for measuring temperatures in liquids and gases.
