NCS-TT105 Temperature transmitter uses digital technology, so it can connect with many types of thermocouple and thermo resistive sensors.  Temperature transducer has wide range and simple interface between field and control room, which reduces the expense of installation, operation and maintenance.

NCS-TT105 temperature transducer supports HART, FF, and PA protocols. It can be widely used in the petroleum, chemicals, electricity, and metallurgical industries, etc.

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, as shown in the picture

(1) Terminal board: it is used to connect with bus, temperature transmitter, instrument board and communication board.

(2) Instrument board: it can convert the temperature transmitter 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.
