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.

Key Features of SI-SBW Field Mounted HART Temperature Transmitter

High Definition Display of SI-SBW HART Temperature Transmitter

• 0, 90, 180, & 270 degree position adjustments
• Monitoring, programming and diagnostics view
• Extensive diagnostics with flashing red or white backlight

Local Operator Interface (LOI) of SI-SBW HART Temperature Transmitter

• 3 optical buttons; up, down and enter
• Dynamically adaptive to wear or accumulation of dirt
• Immune to interference from ambient light sources
• Useable with or without gloves

Configuration of SI-SBW HART Temperature Transmitter

SI-SBW HART Temperature Transmitter Mounting / Installation

• For installation in zone 0, 1, 2 and zone 20, 21, 22 and in Class 1, Division 1 and 2 applications
• Hardware assessed for use in SIL 2 applications
• Mounting on 1.5”–2” pipe bracket or on wall / bulkhead

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.
