Description
For the temperature monitoring of units, mechanisms and technological manufacture processes use of sensors which convert temperature to electric signal is preferable. Metal and semiconductor resistance thermometers, thermocouples and thermodiodes are such sensors. Comparative characteristics of these sensors are given in Tab. 1.
Temperature ranges which are subject to monitoring and control in a number of the most important branches of engineering are represented by Tab. 2. Comparison of these data shows that in majority of cases temperature has to be measured in the range of 190 ¸ 450 K. It appears that thermodiode sensors are the most suitable for this purpose because they are superior to all other sensors in sensitivity, output signal level, cost and simplicity of use. Their salient feature is the possibility of connection with the measuring unit by means of two-wire connection line of length from some tens meters to some kilometers.
