Converter 2xPt100 1W-UNI: Measuring Pt100 and Pt1000 temperature

Double converter to connect two Pt-100 and Pt-1000 probes to 1-Wire UNI (RJ11). One or two external temperature probes can be monitored over LAN (Poseidon2) and GSM (Ares).
Typical applications include measuring extreme temperatures in furnaces, coolers, engines, etc.

The converter connects one or two Pt100 or Pt1000 platinum temperature sensors to the 1-Wire UNI bus. Pt100 probes are available in numerous form factors designed for various uses.

The “Converter 2xPt100 1W-UNI” can be connected to Poseidon2 or Ares units. The values can be shared over LAN or GSM.
 

  • The converter automatically detects Pt100 and Pt1000 probes
  • Measured temperature range is -200 to +850 °C (-328 to 1560 °F)
  • The external probes can be connected using 2, 3, or 4 wires
  • The converter is powered from the 1-Wire UNI bus (RJ11)
  • High temperature measurement accuracy, auto-range
  • Sensors can be daisy-chained (two RJ11 connectors)
  • Converter can be calibrated at 8 points

 

Applications

  • Accurate measurement of temperature in a wide range
  • Cooling plants with built-in temperature sensors at fixed locations
  • Large-scale measurement systems with many measuring points

    • Can I connect external Pt-100 or Pt-1000 temperature probes to HWg-STE plus?
      No, external Pt100 and Pt1000 probes are connected using the Converter 2xPt100 1W-UNI. This converter cannot be used with Poseidon1 products or HWg-STE (HWg-STE PoE) and HWg-STE plus web thermometers.
    • Can I use the converter with only one Pt-1000 or Pt-100 probe?
      Yes. The second probe will either read as -999.9 (indication of disconnected sensor) or turn off automatically.
    • Is there a difference between 2-wire and 4-wire connection of the external temperature probe?
      Yes, 4-wire connection allows the most accurate measurement. The difference is noticeable especially with longer wires.
    • I have an external sensor connected but Poseidon2 shows weird values (5000 °C and so on). What is the problem?
      Double-check the wiring and connection of the Pt-100 or Pt-1000 probe, according to the manual. Are the jumpers for unused terminals properly in place?
    • Can I connect any Pt-100 or Pt-1000 probe?
      Yes. You can use a genuine HW group PT100 probe, or any other Pt100 or Pt1000 temperature probe.
