Equipment

The 40C anemometer was one of the first anemometers designed specifically for the wind energy industry. Its bearings and low moment of inertia allow it to respond very quickly to gusts and lulls. Thanks to its linear output, the sensor is ideally suited for use with various data acquisition systems. A four-pole magnet induces a sinusoidal voltage in the coil, generating an output signal with a frequency proportional to the wind speed.

The NRG S1 anemometer provides a unique balance of high accuracy and low cost, making it ideal for reducing measurement error during wind resource assessment campaigns as well as for facility monitoring. The proven bearing system and robust metal housing design ensure reliable sensor operation for many years in a variety of environmental conditions.

The NRG S1 anemometer is the only wind energy anemometer conforming to both editions of the IEC 61400-12-1 standard, which makes it easy to compare it with both new and legacy anemometers.

The Thies First Class anemometer is designed to measure the horizontal component of wind speed in the field of meteorology and environmental measurement technology, site assessment and power performance measurement of wind power systems. In flat terrain, the wind sensor meets all the requirements of the IEC 61400-12-1 standard for an instrument of accuracy class 0.5 (classification S).

NRG Systems’ 200M wind direction vane brings significant upgrades to the proven design of the 200P wind direction vane. Made from the same high-quality, UV-stabilized materials as the 200P, the 200M boasts 360° continuous measurement capability, lowering measurement uncertainty. Improvements to the 200M’s sensing element also lower measurement uncertainty by improving sensor accuracy.

The Thies First Class wind vane is designed to determine the horizontal component of wind direction in the field of meteorology and environmental measurements, site assessment and power performance measurement of wind power systems. The measured value is output as an analog signal. The output signal can be transmitted to indicators, recording devices, data loggers, as well as to process control systems.

The 2D ultrasonic anemometer is designed for two-dimensional measurement of the horizontal components of wind speed and direction, as well as the acoustic-virtual temperature. Compared with classical anemometers, the ultrasonic measuring principle makes it possible to measure variable quantities in operation without inertia and with the highest accuracy. It is particularly suitable for measuring gust and peak values.

The NRG BP65 barometric pressure sensor is well suited for measuring atmospheric pressure in wind and solar resource studies at remote sites, in particular for calculating air density and annual energy production. Its robust housing protects the high-precision sensing element, ensuring reliable operation in various climatic conditions.

The BP65 retains the proven design of its predecessor, the BP60, ensuring a smooth transition to this next-generation sensor.

The NRG T60 temperature sensor is a new sensing element that complements the time-tested design of the NRG 110S. The result is a durable and reliable sensor that provides lower measurement error and is capable of performing measurements at higher temperatures. Since the T60 has the same physical design, output signal and wiring diagram as the 110S, the transition to this next-generation sensor is exceptionally simple.

The NRG RH5X sensor is compatible with the NRG range of data loggers, including the LOGR | Met data logger, LOGR | Solar data logger, LOGR-S data logger and SymphoniePRO data logger.

The RH5X sensor features a polymer resistive sensing element that provides excellent linearity and sensitivity with fast response and long-term stability. It is attached to the bottom of the protective box and includes a 1.5 m (5 ft) cable, a mounting bracket and one hose clamp.

The device is equipped with a built-in pressure sensor and a replaceable hygro-thermo module for measuring air temperature and relative humidity.

The replaceable hygro-thermo module and the pressure sensor are adjusted and calibrated at the factory. The sensor is supplied without a filter cap. The hygro module is protected by its own white membrane. As a result, the sensor provides excellent dynamic performance. A Pt1000 measuring element is used for temperature measurement.

SymphoniePRO is an industrial low-power data logging system specifically designed for resource assessment in the renewable energy industry. If necessary, the measurement capacity of the logger can be optimized using 26-channel or 16-channel mounting panels. The statistical values of each channel are calculated from continuous 1-second data samples and averaged over a user-selectable interval (10 minutes by default). The collected data is efficiently stored as binary *.RLD files in the internal flash memory, with a backup on an external SD card, if installed.

The Meteo-42 is easy to set up — in your office or directly on site — using the same communication tools and software as the Meteo-40 plus: AmmonitConnect and AmmonitOR cloud. Ammonit data loggers are easy to install and work reliably worldwide.

The Meteo-42 offers the following technical innovations:

Three RS-485 ports

Faster processors

Improved grounding for more accurate measurement of analog values

More flexible switches
