PR Electronics HART 7 temperature converter, loop-powered

PR-3337

Loop Powered / Pt100, TC J and K temperature converter with Hart Signal output.
High accuracy, better than 0.05% of span
Slimline housing of 6.1 mm
Excellent EMC performance
Selectable 60 ms / 60 s response time
Pre-calibrated temperature ranges selectable via DIP-switches

Application

  • The 3337 temperature converter measures a standard Pt100, TC J and K temperature sensor, and provides an isolated passive analog current and HART signal output.
  • High 2 port isolation provides surge suppression and protects the control system from transients and noise.
  • The 3337 can be mounted in the safe area or in Zone 2 / Division 2 areas.
  • Approved for marine applications.

Technical characteristics

  • Flexibly loop powered by 6.2...35 VDC via 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 3337 provides top measurement performance in harsh EMC environments.
  • The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
  • 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.
  • Selectable HART-mode to enable full HART read-write capability.
  • The narrow 6.1 mm housing allows up to 165 units to be mounted per meter of DIN rail, without any air gap between units.
  • Wide ambient temperature range of -25...+70°C.
