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. Our intelligent temperature transmitter outputs a 4-20mA DC signal, simultaneously superimposed in line with HART standard protocol communication. Additionally, the intelligent flow integrator offers isolated temperature transmission. With a 500V isolation voltage, it enhances resistance to common mode interference, making it ideal for computer networking applications.
