In the early stages of refining crude oil has to go through selective hydrogenation steps. During these steps, the temperature is a key process variable that has to be monitored carefully.
When critical temperatures have to accurately and reliably be monitored, turn to the TDZ3 Smart HART Temperature Transmitter. The TDZ3 is a dual input capability that allows two sensors to be monitored in a primary and secondary configuration. Should the primary sensor fail, the TDZ3 will automatically switch over to the secondary sensor and send out a HART diagnostic alarm. The TDZ3 also has advanced sensor diagnostics that allow sensor drift detection and thermocouple impedance levels for thermocouple burnout situations. The TDZ3 also comes with full worldwide hazardous areas approvals.
Key attributes:
- Dual input for failover/backup
- HART or DTM programmable
- Advanced sensor diagnostics and worldwide hazardous areas approvals
