The NR series sheathed resistance thermometers are the high performance resistance thermometers with high sensitivity, solidity, and durability required in a general industrial sensor. The thermometer is constructed by densely filling the gap between a protective tube and a resistance thermometer element with magnesium oxide. The thermometer has excellent response. vibration resistance and impact resistance, and withstand long-term continuous operation in hot and unfavorable environment.
