Resistance -Temperature Characteristics

The resistance of a temperature is solely a function

of its absolute temperature. Since electrical power

being dissipated within a temperature might heat

above its ambient temperature and thereby reduce

its resistance, it is necessary to test for resistance

with temperature. The resistance so measured is

called RT, which means the resistance at essentially

zero-power.

Where: Ra is the resistance at absolute temperature T1

Rb is the resistance at absolute temperature T2

THERMISTOR

"Thermistor" is the generic name given to

thermally sensitive resistors.

Negative temperature coefficient thermistor

is generally called as thermistor. Thermistor

is a semiconducting ceramic resistor

produced by sintering the materials at high

temperature and made mainly from metal

oxide.

Depending on the manufacturing method

and the structure, there are many shapes

and characteristics for various purposes

such as temperature measurement,

temperature compensation and etc.

The thermistor resistance values, unless

otherwise specified, are classified at a

standard temperature of 25ꢂC.

is a constant which depends on the

material of the thermistor

Unless otherwise specified,all values of B are

determined from measurements made at 25ꢂC and

85ꢂC.

The temperature coefficient of resistance

ꢌ is expressed in the following equation:

The mathematical expression which relates the

resistance and the absolute temperature of

a thermistor is as follows:
