- Can be directly replaced with standard thermocouples and thermal resistances for enhanced flexibility.
- Utilizes thermocouple temperature changes to eliminate the need for compensation wires, thereby reducing overall costs..
- Equipped with LCD, digital tube, and pointer indicators for convenient and timely on-site monitoring..
- When the ambient field temperature exceeds 70°C, the transmitter and field display instruments can be installed separately to ensure optimal functionality.
- Explosive Grade: dIICT6Gb
- Protection Grade: IP65
Sophisticated Technical Parameters:
Input Signal:
Thermal Resistance: Pt100, Cu50, Cu100 (three-wire, four-wire)
Thermocouples: K, E, J, B, S, T, N.
OUTPUT: 4-20mA DC Signal
The device outputs a 4-20mA DC signal across the range, directly proportional to the input signal from the thermocouple or thermal resistor, or linear to temperature. Our intelligent temperature transmitter also overlays HART standard protocol communication onto the 4-20mA DC signal. Featuring an isolated temperature transmitter and flow integrator, the device ensures input and output are isolated with a robust 500V isolation voltage, enhancing resistance to common mode interference and making it ideal for computer networking applications.
