El WindSonic4 es un anemómetro ultrasónico de dos dimensiones que mide la velocidad y dirección del viento. Es una alternativa a los anemómetros y veletas convencionales con partes móviles y mecánicas. Este sensor transmite los datos por SDI-12, que directamente pueden leer nuestros dataloggers.

El Windsonic1 no se recomienda para aplicaciones donde se produzca escarcha, hielo o nieve horizontal. Este sensor no incluye calentador. Contáctenos para información sobre versión con calentador.Leer más
The WindSonic4 uses two pairs of orthogonally oriented transducers to sense the horizontal wind. The transducers bounce the ultrasonic signal from a hood, thus minimizing the effects of transducer shadowing and flow distortion.
Unlike mechanical anemometers, the WindSonic4 has no moving parts to be periodically replaced—minimizing routine maintenance costs.

The WindSonic4 is shipped with the 17387 mounting kit. This mounting kit is used to attach the sensor to a CM202, CM204, or CM206 crossarm. The crossarm is then mounted to a tripod or tower.
The WindSonic4 is connected to one control port, +12 Vdc, and ground. Up to ten WindSonic4s (each with a unique address) can be connected to one data logger control port.
The SDI12 instruction is used to collect data from the WindSonic4.

There are no user-serviceable parts on the WindSonic1 and WindSonic4. Should the WindSonic require service, it will start setting diagnostic flags. Campbell Scientific recommends that all data logger programs record the total number of times the flags are set in an output period. For details, see the WindSonic Instruction Manual.
Yes, as long as these two conditions are met:
All WindSonics (option 1 or option 4) are shipped from Campbell Scientific with an interface cable. If the cable has been lost, order a replacement. Order model WINDSONIC1CBL-Lxx for an option 1 or WINDSONIC4CBL-Lxx for an option 4, where xx is the cable length. The maximum cable length is 50 feet for option 1. The maximum cable on the SDI-1 bus is 200 feet.
The fastest output frequency is 4 Hz for the WindSonic1 and 1 Hz for the WindSonic4.
The WindSonic is not suitable for measuring the vertical wind component. The WindSonic measures the wind that passes through its measurement volume. It does not care what the orientation is. If the WindSonic is turned on its side, the reflecting top and body of the sensor will cause massive flow distortion of the wind vector, specifically for the horizontal component that is perpendicular to the reflective top. This flow distortion will most likely result in erroneous vertical wind measurements.
Not every sensor has different cable termination options. The options available for a particular sensor can be checked by looking in two places in the Ordering information area of the sensor product page:
If a sensor is offered in an –ET, –ETM, –LC, –LQ, or –QD version, that option’s availability is reflected in the sensor model number. For example, the 034B is offered as the 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, and 034B-QD.
All of the other cable termination options, if available, are listed on the Ordering information area of the sensor product page under “Cable Termination Options.” For example, the 034B-L Wind Set is offered with the –CWS, –PT, and –PW options, as shown in the Ordering information area of the 034B-L product page.
Note: As newer products are added to our inventory, typically, we will list multiple cable termination options under a single sensor model rather than creating multiple model numbers. For example, the HC2S3-L has a –C cable termination option for connecting it to a CS110 instead of offering an HC2S3-LC model.
Most Campbell Scientific sensors are available as an –L, which indicates a user-specified cable length. 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:
If a sensor does not have an –L or other –LX designation after the main model number, the sensor has a set cable length. The cable length is listed at the end of the Description field in the product’s Ordering information. 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.
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 designates the sensor as a 034B for an ET107 system.
The fundamental measurement frequency of the WindSonic is 40 Hz (40 measurements per second). These measurements are then averaged to give an output at some slower output frequency. For a WindSonic programmed to produce 1 Hz data, all 40 measurements are averaged. (This is called a block average.) For a WindSonic that is programmed to produce 4 Hz data, each output is the block average of 10 fundamental measurements.
Many Campbell Scientific sensors are available with different cable termination options. These options include the following:
Note: The availability of cable termination options varies by sensor. For example, sensors may have none, two, or several options to choose from. If a desired option is not listed for a specific sensor, contact Campbell Scientific for assistance.
