TC measure temperature use the pyroolectricity. Its measuring range from -40~1000ºC. And it can send 4~20mA signal. It use in measuring high or medium temperature.
The quality standard is : JB/T9238-1999 , 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 1700ºC, 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: 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.
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.
