Temperature probe- Threaded RTD

 

 

Features

1. Small external diameter, quick heat responsive period

2. may be bent, long use life, fine air-tightness, wide thermometric scope

3. high voltage resistant, anti-vibration

4.can be used in narrow mounting pipeline or under bending conditions

Working principle

RTD measure temperature according to the characteristic of metal wire changes electrical resistance along with temperature, the thermoelement of RTD is made by metal wire be wound on the surface of insulation skeleton. If there is temperature gradient in the measured medium, the measured temperature is an average temperature of element in the range of the medium zone.
