Configuration Options

Originally designed for marine environments, the P2546-OPR is ideally suited for wind resource assessment and power performance studies both onshore and off.

There are three versions of the P2546-OPR sensor: the P2546C-OPR (coil version), the P2546D-OPR (electronic version) and the P2546A-OPR (reed switch). Both versions of the sensor are fully compatible with all Symphonie series data loggers. However, NRG discontinued sales of the P2546A-OPR Anemometer as of July 2017 due to restrictions related to its mercury content. You will need to use when connecting more than six anemometers to a ; please see the table below for details. These sensors can also be integrated seamlessly with our .
