Description

  • RTD, thermocouple, potentiometer, linear resistance and bipolar mV input
  • Single or true dual inputs with sensor redundancy and drift detection
  • Wide ambient operating temperature of -50 to +85°C
  • Total accuracy from 0.014%
  • 2.5 kVAC galvanic isolation
  • Full assessment to IEC61508 : 2010 up to SIL 2/3

Common HART Temperature Transmitter Applications

  • 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

  • True dual input HART temperature transmitter. The high-density 7-terminal design accepts the widest range of dual input combinations.
  • Sensor redundancy – output automatically switches to a 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 minimum / maximum 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.
