atlas copco temperature sensor

The definition of the temperature sensor:

the use of substances of various physical properties with the temperature variation of the temperature is converted to electricity. Thermometer to reach thermal equilibrium by conduction or convection, so that the thermometer showing the value of the temperature of the object under test can be expressed directly. Generally higher measurement accuracy. Within a certain temperature range, a thermometer, temperature distribution inside the object can be measured. Can be used for measuring the temperature within the range of 1.6 ~ 300K.

temperature sensor Working Principle

When composed of two different conductors and semiconductors in a loop, both ends thereof are connected to each other, as long as the two nodes at the temperature, one end temperature is called the working end or hot end, the temperature of the other end as a free end (also called the reference terminal ) or the cold side.

temperature sensor Material properties

Varies with temperature, the resistance value of the conductor changes, to deduce the temperature of the object under test by measuring its resistance, the use of this principle constitutes the sensor is a resistive temperature sensor, such a sensor is mainly used for -200-500°C temperature range within the temperature measurements. The pure metal manufacturing materials, thermal resistance and heat resistance of the material should have the following characteristics:

1) temperature coefficient of resistance to be large and stable, and should have a good linear relationship between the resistance value and the temperature.

2) high resistivity, heat capacity, fast response.
