Subject: | TWP/SMET/C3 - Wind Speed data contain offset due to induced voltage |
DataStreams: | twpsmet60sC3.b1
|
Description: | The marine model of the RM Young wind sensor needs twisted pair shielded cable. The
manufacturer did not originally supply the pigtail with twisted pair shielded cable. Use of
twisted pair shielded cable for the rest of the cable run to the logger was also not
specified. This caused an induced voltage in the wind speed line from the wind direction
excitation. The induced voltage varied from sensor to sensor and probably changed anytime
the cable was replaced or parts of the wind sensor were repaired or replaced. The induced
voltage has been seen to vary from 0.15 m/s to as much as 1.08 m/s. |
