Two models of Nevzorov Probes exist (CWCMB2 and CWCMU4) which operate after the same principle. Each system consists of a control box and a sensor head. Operation of the Nevzorov probes requires experienced staff on board the aircraftThe differential pressure transducer setra 239 with a pressure range of 0-30 INWC (inch water column) is permantly installed in both aircraft as part of the Basic Meteorology module. Additionally, the pressure transducer setra 239 with a pressure range of +/- 7.5 INWC is installed in nose booms used for turbulence measurements. |
