Anemometer calibration7/3/2023 ![]() ![]() For example, the 034B-ET model designates the sensor as a 034B for an ET107 system. ![]() If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model has a description of “Met One Wind Set for ET Station, 67 inch Cable.” Products with a set cable length terminate, as a default, with pigtails. The cable length is listed at the end of the Description field in the product’s Ordering information. If a sensor does not have an –L or other –LX designation after the main model number, the sensor has a set cable length. ![]() An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.An –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.If a sensor is listed as an –LX model (where “X” is some other character), that sensor’s cable has a user-specified length, but it terminates with a specific connector for a unique system: Most Campbell Scientific sensors are available as an –L, which indicates a user-specified cable length. The allowed limits for this test assure that the temperature influence on the calibration is within the specified limit. After run-in, bearing friction is tested at -15☌ and at room temperature. All units are run-in for 225 hours at 9 ms -1, in order to reduce the initial bearing friction to a level close to the steady state value. Variation among units designates the maximum deviation of any unit from the straight line representing these mean values. The specified offset and gain figures represent the mean values of these calibrations.
