The 444-3H type intelligent temperature transmitter, can receive 2-, 3- and 4- thermal resistance, thermocouple and resistance and MV input, with HART communication protocol or foundation field bus communication function. When using the HART communication protocol, output is linear with the input of 4-20 mA/HART; and when the Foundation Field bus communications, for full digital output.

Characteristics of Temperature Transmitter

The HART or foundation field bus communication

· Transmitter and sensor matching function, the specified temperature impedance curve input transducer RTD sensor, transmitter and sensor can achieve the perfect matching, avoiding the interchangeability of error sensors, can improve the accuracy of 75%

· Accuracy: 0.03% range +0.15 ℃ (Pt100 for example)

· Stability: thermal resistance and thermocouple input, 24 months, or 0.15 ℃ ± 0.15% readings, to whichever

· Wide range: -200~1768 ℃, (set scale in the sensor range, no limit)

The number of · advanced self-diagnostic function can be reduced to a field repair

· Eemperature correction circuit, reduce the influence of environmental temperature

· Input / output electrical isolation

· Excellent electromagnetic compatibility

Independent parallel alarm circuit design

For the input options can be arbitrary configuration
