Intelligent temperature transmitter, which can be used in conjunction with unit combination instruments, PLC, DCS and other systems, is widely used in major industries such as oil fields, power, petrochemicals, manufacturing, metallurgy, etc

Widely used in engineering. Capable of inputting single or dual thermocouple and thermistor signals, transmitting and outputting isolated single or dual linear current or voltage signals, and improving the electrical connection between input, output, and power supply

Isolation performance. The following introduces the technical characteristics and parameters of intelligent temperature transmitters:

Technical characteristics of universal intelligent temperature transmitter:

The digital technology used in the intelligent temperature transmitter has multiple performance advantages that traditional analog instruments do not possess. It has excellent performance in suppressing low and high frequency interference signals, even in large environments

The power frequency conversion control system can still be reliably applied, and at the same time, the application of digital technology overcomes the shortcomings of traditional temperature transmitters with poor linearity. It adopts zero free, digital calibration, and full potentiometer internally

Various technologies such as automatic dynamic calibration of zero point, automatic compensation for temperature drift, etc., and compliance with the requirements for electromagnetic interference resistance of products in Class IV (harsh industrial sites) environments specified in IEC61000-4-4:1995

The application of a series of technologies ensures the scientific guarantee of product reliability and stability.
