Industrial heat resistance as a temperature measurement sensor, usually display instruments, recording and supporting the use of electronic regulator, which can directly measure or control a variety of production processes within -200 ¡æ -600 ¡æ of liquid, vapor and gases, and Solid surface temperature.
According to state regulations, I produced the dividing line with international standards IEC Pt100 platinum resistance issue and in accordance with professional standards sub-degree numbers Cu50 copper fabricated two types of thermal resistance, thermal resistance unified design¡£
