Humidity - Measurement and Monitoring of relative Humidity

HC2A-IE02-XX Screw-In Probe - Stainless Steel Probe for pressurized conduits and vessels

The Rotronic industrial screw-in probe is especially suitable for high temperatures up to 200 °C and demanding industrial environments with applications in which pressures prevail. It measures humidity and temperature and is compatible with the HF5, HF8 series measurement transmitters, HP32 and HP23 handheld devices and the HL-NT dataloggers.

Advantages of the industrial probe

  • Pressure resistant up to 100 bars
  • Wide temperature measurement range -100…200 °C
  • Outstanding accuracy
  • repeatability and long-term stability
  • Advanced probe housing and construction
  • Hot swappable, no calibration adjustment required due to the digital interface with Rotronic devices

Applications of the probe

  • Industrial manufacturing
  • Drying processes
  • Food and pharmaceutical manufacturing

Smart electronics

  • Based on the Rotronic’s AirChip3000
  • Calculates the dew / frost point
  • Alarm generation
  • Saves adjustment data so that probes can be
  • interchanged without re-adjusting
  • Can be cable mount up to 5 m
  • Hot-swappable

Flexibility and compatibility of the industrial probe

  • User scalable analog ouput signals (2x 0…1V)
  • Digital interface via UART
  • Rapidly interfaced with HygroClip2 compatible devices from Rotronic or for OEM applications
