Removal and check of the sensor of temperature

Fig. 1. Scheme of check of the sensor of temperatures

1–variable resistor of 10 kiloohms;
2–storage battery;
3–voltmeter;

4–миллиамперметр;
5–sensor.


 PERFORMANCE ORDER

We disconnect the storage battery.
Pricker or thin screw-driver having hooked a spring clamp of a block of wires, …

… we disconnect a block from the temperature sensor.

We merge cooling liquid (see. Replacement of cooling liquid).

Key «on 19» we turn on...

... also we remove the sensor.

We collect the scheme of check of the sensor of temperature see fig. 1.
The last we connect wires to plugs of the storage battery, having convinced that the scheme is collected correctly.

The variable resistor with the help миллиамперметра we establish a current in a chain in the range from 1 to 1,5 мА.

By the voltmeter we measure tension in a chain at room temperature (about 20 °C).

Consistently lowering the sensor in heated up to temperature 25, 40, 60, 80, 90 and 100 °C water, according to indications of the voltmeter we make the thermal characteristic of the sensor.

The serviceable sensor in a chain should have a close tension to the sizes specified in the table.

The faulty sensor is replaced.
We establish the temperature sensor in return sequence, having put on its carving hermetic.
