Principle and Structure Of NCS-TT105 Temperature Transmitter
This article will show principle and structure of NCS-TT105 temperature transmitter.
NCS-TT105 temperature transmitter uses resistive temperature detectors (RTD) or thermocouple and converts to fieldbus signal in order to measure temperature.
NCS-TT105 temperature transmitter consists of five components.
1)Terminal board: it is used to connect with bus, temperature sensor, instrument board and communication board.
2)Instrument board: it can convert the temperature sensor signal to voltage signal, and then provides the digital signal to board via A/D.
3)Communication board: it is the core of smart instrument, providing the functions of fieldbus communication, control, diagnosis and maintenance.
4)Isolation board: it is used for isolation between communication board and instrument board (including power isolation and signal isolation).
5)Display board (optional): it is used to display temperature and function block parameters.
