5.8 Air/Water-Cooled Housing

The Air/Water-Cooled Housing accessory allows the sensor to be used in ambient temperatures up to
120°C (250°F) with air-cooling, and 180°C (356°F) with water-cooling. The cooling media should be
connected using 1/8" NPT fittings. Air flow should be 1.4 to 2.5 l/sec at 25°C (77°F). Water flow should
be approximately 1.0 to 2.0 l/min (water temperature between 10 and 27°C (50 to 80.6°F). Chilled water
below 10°C (50°F) is not recommended, see section 5.8.1 Connecting, page 40.
The Air/Water-Cooled Housing is available in stainless steel (...S) and aluminum (...A) and includes the
air purge collar.
