Product Description

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 transducer Material properties

Varies with temperature, the resistance value of the conductor changes, to deduce the temperature of the object under test bymeasuring its resistance, the use of this principle constitutes the transducer is a resistive temperature transducer . temperature range within the temperature measurements. The pure metalmanufacturing 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 theresistance value and the temperature.

2) high resistivity, heat capacity, fast response.
