Rail type intelligent temperature transmitter
Introduction to the Performance of Rail type Intelligent Temperature Transmitter
Rail type intelligent temperature transmitter 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.
Technical characteristics of rail type intelligent temperature transmitter
The guide rail intelligent temperature transmitter adopts advanced digital technology, which has many advanced performances that traditional analog instruments do not have. It has excellent performance in suppressing high and low frequency interference signals. It 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, and many advanced technologies such as digital calibration, zero free and full degree potentiometers, automatic dynamic zero calibration, automatic compensation for temperature drift, etc. are used internally, which are consistent withIEC61000-4-4:1995The fourth category specified in the regulations(Adverse industrial site)Environmental requirements for electromagnetic interference resistance of products,The application of this series of technologies ensures the stability and reliability of the product through scientific means. The above technologies are leading the international advanced level.
Applicability
The rail type intelligent temperature transmitter 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.
