Page History

Temperature sensors are permantly installed in a de-iced Rosemount housing in both aircraft as part of the Basic Meteorology module. Additionally, temperature sensors are installed in nose booms used for turbulence measurements. Here two sensors are used - one in a de-iced and one in a not de-iced Rosemount housing.

The setra 239 model is used for measuring differential pressure for the basic meteorology at the nose of the aircraf. Additionally, it is used with the Turbulence Noseboom where setra239 transducers are connected to a 5-whole probe. The Model 239 is a transducer designed for extremely low pressure ranges (+/- 2.7 inch WC) and a wide temperature range (-18 to +80°C).
