Configuration Options

The NRG BP60 Barometric Pressure Sensor is well-suited for the barometric pressure measurement requirements of wind and solar energy studies, particularly as an input to air density, annual energy production calculations, and more reliable forecasts on operational solar and wind farms.

The BP60  introduces a new sensing element, dramatically improving the accuracy of barometric pressure measurements compared to the legacy BP20 sensor. The most significant enhancement is the introduction of native temperature-compensation, discussed in greater detail on the NRG blog.

Each BP60 unit undergoes a single-point check to confirm performance within the sensor’s specifications, the results of which are available in a factory verification certificate at no additional cost. A three-point calibration is also available.

*Please note: BP60C is the calibrated version of this sensor.

  • Improved sensor accuracy thanks to a new sensing element means lower measurement uncertainty
  • Native temperature-compensation enables more reliable forecasts on operational solar and wind farms
