1.Materail of RTD : platinum rtd and copper rtd
2.Gained CE and ISO9001:2000
3.High quality and competitive price
Assembly RTD as temperature sensor in industry
Features:
1. Small external diameter, quick heat responsive period
2. long use life, wide thermometric scope
3. high voltage resistant, anti-vibration, fine air-tightness
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.
Temperature measuring range and Tolerances
Calibration | Nominal resistance(0°C) Ω | Temperature measuring range °C | tolerance | R100/ Ro w |
Pt10 | 10 | ceramic elements:-200 ~ 600 mica elements: -200 ~ 420 | ClassA: ±(0.15+0.2%|t|) ClassB: ±(0.3+0.2%|t|) | 1.3851 |
Pt100 | 100 | |||
Cu50 | 50 | -50 ~ 100 | ±(0.3+0.6%|t|) | 1.4280 |
Cu100 | 100 |
Note: The Tolerances of other calibration may consult the above RTD tolerances scope.
