The standard in-line probe AMS 3211-500 with the transmitter AMS 3220 is TÜV-approved according to European and German environmental regulations. The probe is equipped with a ZrO2 sensor, located in the tip of the probe. The probe can be used in applications with solid, liquid and gaseous fuels.
In applications with solid fuels and biomass the probe AMS 3211-500 is equipped additionally with a protective tube to avoid abrasion. For applications in corrosive gases all gas wetted parts are made of INCONEL 600. The standard in-line probe AMS 3211-500 is designed for flue gas temperature up to 500 °C.
Additional product features:
- immersion depth of 150 mm to 3000 mm
- probe tubes made of ceramic or Kanthal, depending on process temperature
- longer life expectancy of the ZrO2 sensor due to the reduced thermal load
- fast and easy sensor replacement
- flanges are available in DIN or ANSI sizes
- continuous monitoring of sensor signal, heater and measuring value on plausibility by the transmitters AMS 3220 or AMS 5200
- back-purge and auto-calibration features are available as options
