Fieldbus Temperature Transmitter


Fieldbus Temperature Transmitter(HART,PA,FF), using the fieldbus technology, is a new generation of  fieldbus temperature transmitter and it is an indispensable field device for process control. Fieldbus  temperature transmitter integrates abundant function blocks and realizes not only general measurement function but also complicated control strategy.
Fieldbus temperature transmitter uses digital technology, so it can connect with many types of thermocouple and thermo resistive sensors. It has wide range and simple interface between field and control room, which reduces the expense of installation, operation and maintenance.
Fieldbus temperature transmitter supports HART, FF, and PA protocols. It can be widely used in the petroleum, chemicals, electricity, and metallurgical industries, etc.

 B housing (DIN 43729) head mounted
 Working temperature: -40 ~ +85°C 
 High accuracy: ±0.1℃ (Pt100, Pt1000)
 Low temperature drift: <±30ppm/℃
 Support thermal resistances (Pt100,Pt1000,Cu50,Cu100 and so on), thermocouples (B,E,J,K,N,R,S,T), resistance signals (0~500Ω, 0~4000Ω) and voltage signals(-100~100mV)
 Thermal resistance supports 2-wiring, 3-wiring and 4 wiring
