Industrial Grade Sonimometer

This sensor is ideal for applications requiring high reliability, NO maintenance, ruggedness, ice-free operation or portability.

Climatronics’ Sonimometer™ (sonic anemometer) (P/N 102779) is designed for ambient wind sensing in harsh environment industrial applications as a direct replacement for conventional mechanical propeller and cup anemometers, both in terms of performance and cost. It requires no periodic maintenance or calibration.

The Sonimometer™ operates on the principle of the measurement of the speed of sound in air. All electronics utilize the latest solid state surface mount technology, conserving power, size, and weight, with a power consumption of less than 0.5W for the unheated version.

The Sonimometer™ measures only 4 inches in diameter and 8 inches high, and the body is slender and aerodynamic to assure that minimum turbulence is introduced into the measured air stream. Measurement interference is further reduced by the transducers being located out of the measurement air stream.

This also serves to increase the reliability and longevity of the sensor as dust, debris, snow, rain, etc, will not impact directly on the transducers.

Standard digital outputs are RS-232C, RS-485 and SDI-12 which are easily interfaced to any of Climatronics’ or other commonly available data acquisition systems. A variety of standard analog outputs are also available. With the flux-gate compass, the wind direction output is automatically referenced to magnetic north. The small size and surface area of this anemometer allows it to be kept ice free even at relatively low power levels. The heated version of this anemometer, P/N 102729, includes the heating elements, which are factory-installed. The heater control box, P/N 102626, is ordered separately.

The Sonimometer™ is now totally field configurable through a very user friendly, software interface, which is accessed through the serial port.
