Sheathed resistance thermometer NR

The sheath resistance thermometer is made by inserting a platinum resistance element inside a metal protection tube (sheath) and sealing it with an inorganic insulation (high-purity magnesium oxide) powder. It has good insulation, confidentiality and vibration resistance.

Excellent insulation and airtightness

There is no air layer inside the protective tube, making the sensitivity acute, and the response is 2 to 3 times better than that of the general type resistance thermometer.
The sheath type structure is resistant to vibration and mechanical shock. It can also be bent, so an L-shaped resistance thermometer without an elbow can also be made.
The Z-type terminal box has a hatch-shaped structure, making it easy to connections to the connecting conductor.
