coolant temperature sensor - a mechanism that is designed to make the temperature of the fluid DC voltage.Through its information can carry out the correction the main parameters which control the motor depending on what its thermal condition.
coolant temperature sensor - a unit that feeds the operating current, which comes from a stable source control unit.Its output voltage can be adjusted.This depends on the ambient temperature.Thus the principle of operation is carried out and the temperature sensor.If it increases - it becomes more and sensor output voltage.
It should tell you how to construct the coolant temperature sensor.It consists of a metal body which has a cylindrical headgear.Inside it is the sensor element.Also, it includes a complete set of plastic tail section with two pin plug.
How to install and set such a thing as the coolant sensor?This mechanism is mounted on the engine, as a rule, the housing of the block thermostat engine cylinders.A temperature sensor is placed on the receiver of the motor inlet pipe.This mechanism is threaded into the threaded mounting hole, and then, via the sealant, a sealing connection.By the sensor wiring harness is connected through double contact socket latch.It should be noted that these mechanisms enable polar diagram, that is the state of the cliff sensor is equivalent to the reverse inclusion.
There are several types of mechanism.The most common type such as a coolant sensor - thermistor.The resistance of such a mechanism is changed, if the temperature of the liquid is also changing.Most often it thermistors having a negative temperature coefficient.In their resistance decreases with increasing temperature and vice versa, becomes larger when the engine is cold.When it warms up - the resistance decreases when the temperature reaches a minimum - it begins work performed.
Not everyone coolant temperature sensor has a function.Sometimes used machines with dual function.That is, when the temperature reaches a certain level, the electronic control unit varies the voltage so that the readings acquired higher resolution.
on older machines used by other units.In general, they have a switch with two positions.These sensors are only at a specific temperature can be opened or closed.Furthermore, they have a direct connection to the relay in order to be able to switch on and off the cooling fan.Alternatively, it sends a signal to the dashboard, and then starts burning lamp, indicating that the signal is received.Similar sensors (which are single-ended) is sent to the meter that is located on the instrument panel, signal.
