Ideal for wind-energy applications
概览
A100LK 被用于大多数的气象和风能观测领域。低功耗，供电范围广，使其在无交流供电的远距离站点使用中非常受欢迎，Campbell Scientific的数据采集器可测量其脉冲或频率信号。传感器使用阳极氧化铝合金，不锈钢和抗风化塑料材料保证其使用寿命。它也是组成VMS100风监测系统的一部分。图像
技术说明
Rotation of the A100LK’s three-cup rotor is electronically converted to pulse output signals proportional to wind speed. The A100LK produces a higher rate of pulses per revolution (up to 13) compared to relay-based sensors, making it suitable for wind surveying where turbulence needs to be estimated.

Additional Compatibility Information
Data Logger Considerations
The A100LK uses one pulse count channel on the data logger.
Programming
The A100LK 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.

No. Cables are attached and sealed on the sensor by the manufacturer. Whenever possible, purchase a sensor with the desired cable length. Alternatively, a new sensor can be purchased with a foot of cable and then spliced onto the existing cable. Splicing cable together, however, increases the likelihood that water may enter the cable and cause shorting, corrosion, and some other potential issues, which in turn can cause measurement issues. Because of the potential issues, do not splice any sensor cable without first contacting Campbell Scientific to discuss the sensor in detail.

Yes. Every A100LK-L ships with a MEASNET calibration certificate.

It is possible that an older version of Short Cut is being used. Download the latest version of Short Cut.
If the latest version of Short Cut has already been downloaded, open the program.
- Go to Tools | Options and make sure that the Enable Creation of Custom Sensor Files box is checked.
- In the Generic Measurements folder, right-click the type of measurement to be made for the sensor, and select Create Custom Sensor.
- Set the fields according to the sensor’s specification, hide those fields that the user does not need to see after being set, and save the custom sensor file settings with the Save As button.
