The P2546A, manufactured by WINDSENSOR, is a Class 1 anemometer used in wind-energy applications. Wind speed is sensed by a three-cup rotor assembly. Magnets mounted on the shaft cause a switch to close and open two times per revolution. Our dataloggers measure the switch closure and convert the signal to engineering units (mph, m/s, knots). The P2546A anemometer comes with a MEASNET calibration certificate.Read More
The P2546A is constructed with durable anodized aluminum and stainless steel. Its switch has no bounce and has a mechanism that reduces the variation in operating time over the frequency range.

Yes. Campbell Scientific recommends checking the local regulations to ensure that mercury switches are usable in the intended area. If a sensor without the mercury switch is required, contact us for assistance with ordering the P2546C-L.
Yes. Every P2546A-L ships with a MEASNET calibration certificate.
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.
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.
