The Ex-Proof Class Long Transmission Distance Two-Wire 4-20mA DC Temperature Transmitter is an advanced field-mounted integrated temperature transmitter.
This state-of-the-art temperature transmitter unit is designed for precision use with industrial thermocouples and thermal resistance applications.It employs a reliable two-wire transmission mode, ensuring accurate temperature readings across long distances.
The two-wire system is ingeniously designed to serve as a common transmission line for both power input and signal output.It effectively converts signals from industrial thermocouples and thermal resistance devices into 4-20mA output signals that are perfectly linear to the input or temperature readings. This temperature transmitter is essential for modern industrial sites and research institutes, offering a superior alternative for temperature measurement and control in distributed systems and digital bus systems.
Ultra-small (module φ44×18) integration, offering exceptional versatility
Reliable two-wire 4-20mA DC output system
- Extended transmission range with superior anti-interference capabilities

- Easily replaces standard thermocouples and thermal resistances without hassle.
- Utilizes thermocouple temperature changes to eliminate the need for compensation wires, effectively reducing costs.
- LCD, digital tube, and pointer functions provide easy on-site monitoring.
- For field ambient temperatures >70 °C, the transmitter and display instrument can be installed separately (isolated mode)
- Explosive grade: dIICT6Gb
- Protection grade: IP65
Technical parameters:
Input signal:
Thermal resistance: Pt100, Cu50, Cu100 (three-wire, four-wire)
Thermocouples: K, E, J, B, S, T, N.
OUTPUT: Output a 4-20mA DC
signal over the range, linear to the input signal of the thermocouple or thermal resistor, or linear to temperature. This intelligent temperature transmitter outputs a 4-20mA DC signal, simultaneously superimposed with HART standard protocol communication. The intelligent flow integrator features isolated temperature transmission, with both input and output isolated. The isolation voltage is 500V, enhancing resistance to common mode interference, making it ideal for computer networking applications.
