Rhodium iron temperaturesensor

Jinzhengmao Rhodium Iron Temperature SensorRhodium ironThe temperature range of a thermometer is very wide and not affected by ionizing radiation77KTemperature above is less affected by magnetic field environment. The wire wound rhodium iron thermometer has excellent stability and is used as a secondary standard thermometer by many national standard laboratories. Rhodium iron thermometers have a positive temperature coefficient and exhibit monotonic response over a wide temperature range.100Karrive273KBetween them, the resistance changes linearly with temperature.

characteristic

Excellent long-term stability;

The temperature curve above 100K shows a linear response;

Better resistance to radiation effects.
