Intelligent temperature transmitter
Product details
Overview of Intelligent Temperature Transmitter:
Intelligent temperature transmitters have excellent performance in suppressing high and low frequency interference signals, and can still be reliably applied even in high-power variable frequency control systems. At the same time, the application of digital technology completely overcomes the disadvantage of poor linearity of traditional temperature transmitters, which is in line withIEC61000-4-4 : one thousand nine hundred and ninety-fiveThe fourth category specified in the regulations(Adverse industrial site)Environmental requirements for electromagnetic interference resistance of products. Intelligent temperature transmitters input single or dual thermocouple and thermistor signals, transmit isolated single or dual linear current or voltage signals, and improve the electrical isolation performance between input, output, and power supply. Intelligent temperature transmitters can be combined with unit combination instruments andDCS、PLCThe system is widely used in major projects in industries such as oil fields, petrochemicals, manufacturing, power, metallurgy, etc.
