- wider range of applications
- e.g. WikaT32 and Rosemount 644 only 2 x 3W
Dual sensor functions include:
- redundancy
- differential
- average
- minimum / maximum tracking
Sensor Redundancy
Improving Process Uptime and Availability
The new PR 5437 HART Temperature Transmitter includes a sensor redundancy function to reduce potential downtime due to sensor errors.
Advantages
- seamless switch to backup sensor in case of failure
- NE107 compliant alert via HART allowing maintenance scheduling on faulty sensor
- maintains process, preventing downtime and potential loss of production or yield
- avoids potential safety or environmental issues in the event of a sensor failure
Sensor Drift Detection
Maintaining Process Accuracy
The PR 5437 HART Temperature Transmitter includes a sensor drift detection function to ensure accuracy and integrity of process values.
Advantages
- user specifies acceptable sensor drift limits
- NE107 compliant alert via HART and/or user can select analog output error and to alert for scheduling maintenance
- prevents inaccurate values from influencing the process, which could potentially affect yields or production quality
Process Optimization and Reporting via PR 5437 HART Temperature Transmitter
Improving Process Control and Visibility
Dynamic variable mapping and runtime metering, together with programmable sensor limits, offer tight process control, an improvement of safety, and traceability
Advantages
- minimum / maximum tracking records process extremes
