Temperature sensor to measure upto -100 degree Centegrade

[santoshhiremani]

I want to Measure a temperature of -100 degree form an freezing system. The system will be having temperature around -80 to -100 degree centigrade and which can not measure by normal temperature sensor. Please if anybody know the sensor which can measure the temperature upto -100 degree ??? Suggest me the good sensor for my requirement.


Thanks in Advance

You can use thermocouples but I'd use thermoresistor such as PT100:

Most normal (industry standard) temperature sensors like Pt100 or NiCr-Ni thermocouple can measure -100 (or -200) °C.

What's your problem?

Use Pt100+XTR105.
You will be able to set Tmin and Tmax (more information in datasheet of XTR105). Precision will be dependence on adjusting resistor.
