The 014A, manufactured by Met One, is a three-cup anemometer that monitors wind speed for the range of 0 to 45 m/s with a threshold of 0.45 m/s. It connects directly to a Campbell Scientific datalogger, which measures the 014A's pulse signal and converts the signal to engineering units (mph, m/s, knots).
The 014A is constructed of corrosion-resistant, stainless-steel and anodized aluminum. It's three-cup anemometer assembly contains a sealed magnetic reed switch. Rotation of the cupwheel produces a pulse that is directly proportional to wind speed.
The 014A can be attached to a CM202, CM202SS, CM203, CM204, CM04SS, or CM206 crossarm via a 1049 NU-RAIL fitting or CM220 Right Angle Mounting Bracket. Alternatively, the 014A can be attached to the top of a CM106B or a stainless-steel tripod via the CM216 Sensor Mounting Kit.
The 014A uses one pulse count channel on the datalogger.
The 014A is read by the PulseCount Instruction in CRBasic and by Instruction 3 (Pulse Count) in Edlog. Wind speed measurements can be taken and processed with any of the dataloggers.

Replacement sensor cables and bearings can be purchased. They can be replaced by the user, but Campbell Scientific recommends factory replacement.
A replacement reed switch can be ordered. It can be replaced by the user, but Campbell Scientific recommends factory replacement.
The 014A-L sensors use magnets spinning over a mechanical reed switch to sense wind speed. Eventually the mechanical reed switch will fail and will need to be replaced. Replace both the bearings and the reed switch at the same time. For details on replacing bearings and the reed switch, see Appendix A of the instruction manual.

Any mechanical wind speed sensor will need to have its bearings replaced on a regular basis. The 03101-L is a less expensive sensor and does not have a reed switch to replace. It’s easier to work on, and the bearings are less expensive. The turret covering the bearings is longer and protects the bearings better from dust and debris. The cups and sensor body are plastic and more fragile, so careful handling is required, but they hold up well after the sensor is installed.
The 03101-L comes with a ¾ in. pipe. The 014A-L has a 1 in. pipe.
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.
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.
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 an application engineer at Campbell Scientific for assistance.
