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.
