Integrated Temperature Transmitter 

 Integrated temperature transmitter is a temperature sensor and signal converter components, signal converters installed in the cold junction temperature sensor junction box, the temperature sensor resistance affected by temperature or potential effects produced by the conversion produces a differential voltage signal. This signal is amplified by the amplifier, and then the voltage and current transformation, the corresponding range of output 4-20mA current signal. 

 Integration of the temperature sensor Temperature Transmitter (RTD or thermocouple) amplification and signal conversion unit integrated with the organic, the process used to measure the various processes within -200-1600 ℃ liquid, steam and other gas medium or solid surface temperature. It is usually, and display instruments, recording instruments and supporting the use of various control systems. It has a simple structure, installation, use, maintenance and convenient features, has been widely used in petroleum, chemical, metallurgical, power, light industry and other sectors. 

 Main features: 

 l wire transfer. Powered signal converter also sent two wire output signal 

 l output constant current signal (4 ~ 20mA). Anti-interference ability, remote performance. 

 l Used for epoxy resin into a signal conversion module with anti vibration, corrosion, moisture, etc., the thermocouple millivolt signal by the signal converter directly into 4 ~ 20mA current output, with ordinary cable transmission signal, can save expensive compensation wire. 

 l Temperature transmitter with on-site display both the output 4 ~ 20mA current signal, but also read the measured temperature in the temperature field, bringing great convenience to the operator. 

 l high precision, interference, long-term stability, maintenance-free, can be remote (up to 1000 meters).
