39560628 Replacement Air Compressor Temperature Sensor For Ingersoll Rand

Temperature Sensor:

Temperature sensor definition: The use of material physical properties with the law of temperature change temperature into electricity.

Thermometers achieve thermal equilibrium by conduction or convection, so that the value of the thermometer can directly represent the temperature of the object being measured.The general measurement accuracy is high.Within a certain temperature range, a thermometer can also measure the temperature distribution inside an object.It can be used to measure the temperature in the range of 1.6 ~ 300K.

The working principle of the sensor: When there are two different conductors and semiconductors to form a loop, its two ends are connected to each other, as long as the temperature of the two nodes is different, one end of the temperature is called the working end or hot end, the other end of the temperature is free end (also known as the reference end) or cold end.

The resistance value of material properties conductor changes with the temperature change, by measuring the resistance value calculated the temperature of the measured object, using the principle of the sensor is the resistance temperature sensor, this sensor is mainly used for temperature measurement within the temperature range of -200-500℃.

Pure metal is the main manufacturing material of thermal resistance, the material of thermal resistance should have the following characteristics:

1.The resistance temperature coefficient should be large and stable, and there should be a good linear relationship between resistance value and temperature.

2.High resistivity, small heat capacity, fast reaction speed.

3.The material has good reproducibility and technology, and the price is low.Thermistor temperature characteristics.

4.The chemical and physical properties are stable in the temperature range.

At present, platinum and copper are the most widely used in industry, and have been made into standard temperature measuring thermal resistance.
