Additional Compatibility Information


The 034B can be attached to a Campbell Scientific crossarm using a 17953 Nu-Rail fitting or a CM220 Right Angle Mounting Bracket. Alternatively, the 034B can be attached to the top of our stainless-steel tripods via the CM216 Sensor Mounting Kit. The CM216 extends 4 inches above the mast of a CM106B, CM110, CM115, or CM120 tripod.

Data Logger Considerations

The 034B's anemometer uses one pulse count channel on the data logger. Its wind vane requires one single-ended channel and access to an excitation channel (the excitation channel can be shared with other high impedance sensors).


The 034B's anemometer is measured by the PulseCount Instruction in CRBasic, and by Instruction 3 (Pulse Count) in Edlog. The wind vane is measured by the BrHalf Instruction in CRBasic and by Instruction 4 (Excite-Delay-SE) in Edlog. The measurements are typically processed for output with the Wind Vector instruction (not present in the CR500 or CR9000).




034B-L: 14


  1. Wind vane tails are user-replaceable and are available for purchase as pn 13765Replacement Wind Vane Tail for 034B or 034A.

  2. No. A data logger is needed to measure and store data from the 034B-L.

  3. They are completely interchangeable, and no changes are needed.

  4. The sensor does not consume power to operate.

  5. For proper siting of the wind sensor, refer to the 034B-L manual. The 034B-L can be mounted using a 1.00 IPS pipe of any length.

  6. The 034B-L uses a switch closure for wind speed measurement, and the 03002-L uses a low-level ac output for wind speed measurement. Both use a pulse channel on the data logger to measure wind speed.

  7. The information included on a calibration sheet differs with each sensor. For some sensors, the sheet contains coefficients necessary to program a data logger. For other sensors, the calibration sheet is a pass/fail report.

  8. This depends on the information contained in the calibration sheet:

    • If the calibration sheet contains coefficient information, Campbell Scientific keeps a copy, and a replacement copy can be requested.
    • If the calibration sheet does not contain coefficients, Campbell Scientific does not keep a copy. It may be possible to contact the original manufacturer for a replacement copy.
