Performance Overview 
 Single or dual thermocouple input, RTD signal transmission output isolation, single-or dual-linear current or voltage signal, and increase input, output, power supply isolation between the electrical performance. 


 Technical Features 
 The product uses advanced digital technology, with the traditional analog gauges do not have many advanced features in the high and low frequency interference signal suppression, each with outstanding performance, even in high-power frequency conversion control system still can be reliably applied at the same time, digital technology completely overcome the traditional shortcomings of poor linear temperature transmitter, digital tuning internal use, no zero and full scale potentiometer, automatic dynamic zero calibration, automatic temperature drift compensation, and many other advanced technologies, and meet IEC61000-4-4: 1995 set forth in the fourth category (poor industrial field) environment on the product's resistance to electromagnetic interference requirements, this series of technology to make the product stability and reliability of scientific assurance. 
 The above technology leader in the international advanced level. 


 Applicability 
 Instrument can be combined with the unit and DCS, PLC and other systems supporting the use of the oil, petrochemical, manufacturing, electricity, metallurgy and other industries have a wide range of major projects in the application.
