The SI-SBW explosion proof field mounted HART temperature transmitter,
features a local display, HART compatibility, and a 4-20mA output.
The field mounted transmitter is available as a complete RTD,
or thermocouple assembly customized to your process.
Series SI-SBW HART Temperature Transmitter
The Series SI-SBW HART® temperature transmitter is a 2-wire transmitter,
with an analog output.
It has measurement input for resistance thermometers (RTD) in 2-, 3- or 4-wire connections,
thermocouples, resistance and voltage inputs.
The transmitter can be programmed with a PC or HART® protocol hand-held terminal.
These small units can be mounted in Pyromation DIN (Form B) connection heads,
or they can be used for surface mounting by using a 35 mm DIN-rail mounting clip.

SI-SBW HART Temperature Transmitter Application
- Linearized temperature measurement with TC and RTD sensors e.g. Pt100 and Ni100
- HART communication and 4…20 mA analog PV output for individual, difference or the average temperature measurement of up to two RTD or TC input sensors
- Up to 63 transmitters (HART 7) can be connected in a multi-drop communication setup
- Temperature measurement of a wide range of TC and RTD types.
- Conversion of wide span linear resistance and potentiometer inputs.
- Conversion of bipolar mV signals to 4…20 mA.
- Integration into asset management schemes.
- Critical applications requiring superior accuracy and/or sensor redundancy and drift detection.
Technical Characteristics ofSI-SBW HART Temperature Transmitter
- NAMUR NE43 and NE89
- HART protocol revision can be changed by user configuration to either HART 5 or HART 7 protocol
- True dual input transmitter. The high-density 7-terminal design accepts the widest range of dual input combinations.
- Sensor redundancy – output automatically switches to the secondary sensor in the event of primary sensor failure, maintaining uptime.
- Sensor drift detection – alerts when sensor differential exceeds user-defined limits, for maintenance optimization.
- Dynamic variable mapping for process data in addition to the primary variable e.g. dual input features 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.
- IEC 61508: 2010 full assessment up to SIL 3 together with enhanced EMC Functional Safety testing to IEC 61236-3-1.
- Meets NAMUR NE21, NE43, NE44, NE89, NE95, and NE107 compliant diagnostics information.
