644 Temperature Transmitter

Rosemount 644 Temperature Transmitter with Hart 


The wall-mounted 644 temperature transmitter can be connected to a thermal resistor or thermocouple. The LCD shows the current temperature change. 24V DC power supply 4-20MA signal output two-wire system superimposed HART communication protocol.


Transmitter features include:

• Transmitter-sensor comparison function to improve measurement accuracy of the entire system

• Temperature correction circuit to reduce ambient temperature effects

• Independent alarm circuit to detect electronic board and sensor failure

• Performance indicators of at least 3σ

• Accuracy: ±0.15°C (±0.27oF), Pt100 thermal resistance

• Stability: ±0.1% reading or ±0.1°C, whichever is greater, 12 months, RTD and thermocouple input

• Unlimited range settings within the sensor range

• Optional WAGO spring clip terminals provide anti-vibration connection for applications where no tightening is required

Maintainability

• Compatibility with Rosemount HART375 Communicator, Rosemount HART475 Communicator HART-based system, and PC-based AMS device management system

• Improve process efficiency, quality and productivity
