–QD models terminate with the connector for a RAWS-F Quick Deployment Station.

–ETM models terminate with the connector for an ET107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.

–ET models terminate with the connector for an ET107 weather station.

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.

The certificate can be written in either English or Swedish.Ĭustomer website Calibration (KWP) is our customer website, that gives you full control over your measuring devices.

The calibration results are delivered in a digital calibration certificate accredited in accordance with ISO/IEC 17025. The measuring points can be specified by the customer when ordering. The calibration is performed at several selected measuring points within the sensor's measuring range. We can offer accredited calibration up to 35 m/s for most types of sensors, but for larger types of rotating vane anemometers accreditation is limited to a maximum of 10 m/s. air ducts and ventilation systems are common. In the setup with the wind tunnel, air velocity sensors used in e.g. We can also offer calibration in a vertical air flow, with horizontal sensor, to see the effect of self-convection from the sensor. The sensor is calibrated upright in a horizontal airflow. The lower measuring range setup is usually used to calibrate small sensors and hot-wire anemometers which are used to measure small air movements in rooms, draft. We use two types of equipment when we calibrate anemometers, a wheel for low air velocities (0.1-4 m/s) and a wind tunnel for higher air velocities (0.3 - 35 m/s). We also calibrate cup anemometers and ultrasonic anemometers but to a lesser extent.

In addition, some applications require that the measuring instruments used are calibrated in accordance with ISO / IEC 17025.Įxamples of various types of anemometers that we routinely calibrate are hot-wire anemometers, pitot tube static anemometers and rotating vane anemometers. There are several reasons to regularly calibrate your measuring instruments, with one being to increase the accuracy of the measurements taken.
