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.
