PROFIBUS PA temperature transmitter
5450B
- PROFIBUS PA profile 4.0
- RTD, TC, potentiometer, linear resistance and bipolar mV input
- Single or true dual inputs with sensor redundancy and drift detection
- Easy Ex i deployment with conformity to FICSO IEC 60079-27
- Accuracy from 0.04°C
- 2.5 kVAC galvanic isolation
Application
- Temperature measurement of a wide range of TC and RTD types.
- Conversion of wide span linear resistance and potentiometer inputs to PROFIBUS.
- Conversion of bipolar mV signals to PROFIBUS.
- Integration into asset management schemes.
- Critical applications requiring superior accuracy and/or sensor redundancy and drift detection.
Technical characteristics
- True dual input transmitter. High density 7-terminal design accepts the widest range of dual input combinations.
- Sensor drift detection - alerts when sensor differential exceeds user-defined limits, for maintenance optimization.
- Variable mapping for process data such as average, differential and min./max. tracking.
- Groundbreaking digital and analog signal accuracy over full input span and ambient conditions.
- Extensive sensor matching including Callendar Van Dusen and custom linearizations.
- Programmable input limits with runtime metering ensure maximum process traceability and sensor out of range protection.
- Meets NAMUR NE21, NE44, NE89 and NE107 compliant diagnostics information.
Programming
- PROFIBUS PA functions and device-specific parameters are configured via fieldbus communication and the associated DD / DTM / GSD device drivers.
Mounting / installation
- For DIN form B sensor head mounting.
- Mounting in zone 0, 1, 2 and zone 21, 22 including M1.
