Air/Water Cooled Housing
The Air/Water Cooled Housing allows the sensor to be used in ambient temperatures up to 120°C
(250°F) with air cooling, and 175°C (350°F) with water cooling. The cooling media should be connected
using 1/8” NPT stainless steel fittings
requiring 6 mm (0.24 in) inner diameter and 8 mm (0.31 in) outer
diameter for the tube.
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). The maximal pressure limit is 5 bar (73 PSI).
Chilled water below 10°C (50°F) is not recommended, see section 8.3.1
page 54.
The Air/Water Cooled Housing is delivered with appropriate fittings.

For ambient temperatures exceeding 175°C (350°F), the ThermoJacket can be used. This
accessory allows operation at ambient temperatures up to 315°C (600°F)!
