Overview
The 03101 is the three-cup anemometer included with our Wind Sentry Sets. You can purchase it separately if your application requires only wind speed measurements. The 03101 connects directly to a Campbell Scientific data logger, which measures the anemometer's pulse signal and converts the signal to engineering units (mph, m/s, knots).
Key Advantages
Compatible with most Campbell Scientific data loggers
Technical Description
The 03101 uses a cup wheel assembly to measure wind speed. Rotation of the cup wheel produces an ac sine wave that is directly proportional to wind speed. The frequency of the ac signal is measured by a data logger pulse count channel, then converted to engineering units (mph, m/s, knots). Campbell Scientific’s version uses shielded bearings, which lowers the anemometer’s threshold.
Product Notes

Common Accessories
(4)1049
3/4 x 1 in. Nu-Rail Crossover Fitting
The 1049 NU-RAIL Crossover Fitting is used to mount this sensor to a crossarm or a user-supplied 1" IPS pipe. This usage is equivalent to the functionality provided by the CM220 Right Angle Mounting Bracket."
OrderableCM221
Right-Angle Mounting Kit
The CM221 mounts a pipe or tube at 90° to another pipe or tube. It is typically used to attach a sensor with a vertical pipe (including most wind sensors) to a crossarm. The cast aluminum, right-angle mounting bracket has 3.8 cm (1.5 in.) U-bolts and hardware and will accommodate tubing with a 1- to 1.5-in. outer diameter.
OrderableCM216
Sensor Mounting Kit for Top of Tripod Mast
The CM216 Sensor Mount provides a connection point for this sensor to be attached to the top of a CM106B, CM110, CM115, or CM120 tripod.
Orderable39112
DIN Rail Terminal Kit with 1 Terminal and 3 Wires
The 39112 provides the needed DIN rail terminals, separator, and wires to connect any product to a data logger or other peripheral that requires three wires for connection. This kit provides the following wires: black, white, and clear. The color-coding of these wires matches the wire coloring of the product for ease in connection, maintenance, and troubleshooting.

Compatibility
Mounting
The 03101 anemometer is supplied with a galvanized 10-in.-long x ¾-in. IPS threaded pipe, which mounts to a crossarm via a CM220 mount or 1049 Nu-Rail fitting. The 03101 can also be mounted to the top of a CM106B or a stainless-steel tripod via the CM216.
Wind Profile Studies
An ideal application for the Wind Sentry is wind profile studies. For this application, the LLAC4 4-channel Low Level AC Conversion Module can be used to increase the number of anemometers measured by one data logger. The LLAC4 allows data logger control ports to read the anemometer’s ac signals instead of using pulse channels. Data loggers compatible with the LLAC4 are the CR200(X)-series (ac signal ≤1 kHz only), CR800, CR850, CR1000, CR3000, and CR5000.
Data Logger Considerations
The 03101 uses one pulse count channel on the data logger.
Programming
The 03101 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 data loggers.
