Abstract

The continuous monitoring of liquid temperature in cryogenic application is essential requirement from control and safety point of view. . Several factors must be considered when selecting the type of sensor to be used in a specific application Any temperature dependent parameter can be used as a sensor if it fits the requirements of the given application. These parameters include resistance, forward voltage (diodes), thermal EMFs, capacitance, expansion/contraction of various materials, magnetic properties, noise properties, nuclear orientation properties, etc. The two most commonly used parameters in cryogenic are voltage (diodes) and resistance. There are several reasons for choosing diode thermometry or resistance thermometry. Therefore this paper present the demand of precision measurement of temperature is addressed using semiconductor diode type sensor and resistor type sensor by sensor characteristic.
