Product Description:

      Intelligent temperature transmitter has excellent performance in restraining interference signals at high and low frequencies. It can still be reliably applied even in high-power frequency conversion control systems. At the same time, the application of digital technology overcomes the disadvantages of traditional linear transmitters, which is in line with the fourth categories of IEC61000-4-4:1995 (harsh industrial field) environment. Ask. The intelligent temperature transmitter inputs single or double thermocouples and thermal resistance signals, and outputs single or two-way linear current or voltage signals isolated from the output, and improves the electrical isolation performance of input, output and power supply. The intelligent temperature transmitter can be used in conjunction with unit instrumentation and DCS, PLC and other systems. It is widely used in major projects such as oil, petrochemical, manufacturing, power, metallurgy and other industries.
