The general intelligent temperature transmitter input single or double thermocouple, thermal resistance signal, transmission output isolated single or double line of current or voltage signal, and improve the electrical isolation performance between input, output and power supply. Technical characteristics Universal temperature transducer adopts digital technology, with the traditional analog instrument does not have a number of performance, in the inhibition of high and low frequency interference signal has excellent performance, even in high power frequency conversion control system can still reliable application, at the same time, the application of digital technology to overcome the disadvantage of traditional linear differential temperature transmitter, Internal digital adjustment, zero and full potentiometer, automatic dynamic calibration zero, temperature drift automatic compensation and many other advanced technology, And in line with IEC61000-4-4:1995 in the provisions of the fourth category (harsh industrial site) environment on the product of electromagnetic interference requirements, the application of a series of technology to ensure the stability and reliability of the product science. Applicability Universal temperature transmitter can be used with unit combination instrument and DCS, PLC and other systems, in the oil field, petrochemical, manufacturing, electric power, metallurgy and other industries of major engineering has a wide range of applications.
