O2[Translate to Englisch:]

Compact in-situ probe

  • Using heated ZrO2 sensor for wet O2 analysis up to 600°C flue gas temperature
  • With optional special heated solid electrolyte sensor for combustibles measurement
Basic-Equipment
  • Compact probe with flow guidance (hollow) tube, with or without back-purge for flue gas temperature up to 600°C
  • For high temperature application up to 1.000 °C or respectively 1700°C, see models OMS420RT and OMS420HT
  • 4"ANSI 150lbs or DN65 PN6 flange with Ø 60mm probe tube and different lengths
  • Reference air inlet through natural difusion, no air pump is required
  • Rugged industrial plug for power supply and data transfer (2x analog 4-20 mA galvanic isolated, digital RS 485 with Modbus RTU protocol

Available OPTIONS like:

  • COe- combustibles gas measurement
  • Back-purge using compressed air, with solenoid valve control by means of transmitter electronics, incl. adjustable purging intervals (recommended for high dust sites)
