3-Wires PT100 Thermal Resistance Rtd with Screw Connection
Technology of thermal resistance:
Min. insert length: 100mm
The insulate resistance of RTD: When the environmental temperature in (15~35)ºC, the relative humidity ≤80%, the ambient insulate resistance shouldn't less than 100MΩ, the copper resistance's insulate resistance shouldn't less than 50MΩ.The test voltage of the insulate resistance can use the arbitrary value of DC (10~100)V.
Self~heating effect: The allowed max.current of the RTD is (2~5)mA (according to the different element), thereout the temperature rise ≤0.3ºC.
Feature of thermal resistance:
1. Wide measuring range.Compared with the traditional instruments, it extend the temperature measurement range.
2. Widely application scope.Add protective tube, can raise the performance of high-temperature resistant, corrosive-resistant, high-pressure resistant, abrase-resistant, it expand the application scope widely.
3. Convenient to control automaticly and centralization of control
4. As the tranditional temperature sensor, it matched display instrument or record instrument to use, it can display the precise temperature, and also convenient to control automaticly and centralized.
5. Armoured unique structure.Sheath restrictive coating structure raise the level of the sensitivity, improve the availability of the material,can curved measured, greatly extend the measure length.It has the strong pollution-resistant performance and mechanical intensity.
Product description of thermal resistance:
RTD measuring temperature use the priciple that the resistance of conductor semiconductor change according to the temperature. Its measuring range from -200~+600ºC.Its advantages are extreme accuracy. And it can send 4~20mA signal.Usually measure the low or medium temperauure.
The quality standard of thermal resistance:
JB/T8623-1997 , and according to ISO9001:2008 to control the quality.Each product has to inspect temperature test by calibrate oven,appearance test,insulation test,wiring connection test, etc. We ask our supplier provide test report of raw material, each electrical element has to detect, so every finished product has factory test report and data record.We have more than 10 sets temperature calibrate oven for calibrate the different temperature,the highest temperature can be made to 500ºC, the longest immersion length can be made to 3m, and also NCM,milling machine,grinding machine from Japan to ensure the accuracy of the spare part. Self-production proportion of spare part up to 90%
Capability of product research and development of thermal resistance:
Every series product team is consist of a senior engineer and several technical engineers. When we receive the technical request different to exist product, we can customize the product by technical drawing or customize according to the sample.The sampling period is 20 workdays.
