General intelligent temperature transmitter can input single or double circuit thermocouple and thermal resistance signal, transmit isolated single or double circuit current or voltage signal, and improve the electrical isolation performance between input, output and power supply.

Technical features: Universal intelligent temperature transmitter adopts the advanced digital technology, with the traditional analog instrument does not have a number of advanced performance, in both the restraint of the high and low frequency interference signal with excellent performance, even can still reliable application in high power frequency conversion control system, at the same time, the application of digital technology * * * * * * to overcome the disadvantage of traditional linear differential temperature transmitter, internal adopt digital calibration, not zero and full automatic potentiometer, automatic zero dynamic calibration, temperature drift compensation and so on many advanced technologies, And in accordance with the requirements of the four types of (harsh industrial site) environment specified in iec61000-4-4:1995 for the anti-electromagnetic interference of the product, the application of this series of technologies makes the stability and reliability of the product scientifically guaranteed. The above technologies are superior to the international advanced level.

Applicability: universal intelligent temperature transmitter can be used with unit combination instrument, DCS, PLC and other systems, and is widely used in major projects in oil fields, petrochemical, manufacturing, power, metallurgy and other industries.
