Application

  • The 3113 temperature converter measures a standard Pt100, TC J and K temperature sensor, and provides an isolated active analog current and HART signal output.
  • High 3 port isolation provides surge suppression and protects the control system from transients and noise.
  • The 3113 can be mounted in the safe area or in Zone 2 / Division 2 areas.
  • Approved for marine applications.

Technical characteristics

  • Flexibly powered by 24 VDC (±30%) via power rail or connectors.
  • A 60 ms fast response time with simultaneous sensor error detection when selected.
  • Selectable internal/external CJC.
  • Excellent conversion accuracy in all available ranges, better than 0.05% of span.
  • Meeting the NAMUR NE21 recommendations, the 3113 provides top measurement performance in harsh EMC environments.
  • The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
  • A visible green LED indicates operational status of the unit and the input sensor.
  • All terminals are protected against overvoltage and polarity error.
  • High galvanic isolation of 2.5 kVAC.
  • Excellent signal/noise ratio of > 60 dB.

Mounting / installation / programming

  • Selectable HART mode with HART 7 revision protocol enables extended device programming.
  • Selectable DIP-mode for easy configuration of more than 1000 factory calibrated measurement ranges with HART read only feature.
