IMPROVED, INNOVATIVE HEATING - one of the advantages of the Biral 2-axis USA-2 Wind Horizon and the 3-axis USA-1 Wind Professional / Wind Research ultrasonic anemometers

These sensors use improved, innovative heating technology which means that the sensor can be effectively heated using relatively low power.

Biral ultrasonics are truly unique in that they are heated very efficiently while still keeping power requirements within reason.

The 3-axis ultrasonic anemometers from Biral are the first and remain the only 3-axis ultrasonic that is heated. This is due to the unique design with a single central spar for effective routing of the heating elements to the transducer area. Not only is a single central spar effective for the heating but it also provides a known and very small sensor design mechanical error contribution far below conventional designs and truly omni-directional for superior measurements regardless of the instrument orientation compared to wind direction.

The key advantage to the heating design of the Biral ultrasonic anemometers is that a very large proportion of the initially produced heating energy is able to be brought to the transducer face quickly and effectively clearing the snow or ice build up. Because of the design the sensor head does not need any dedicated heating in itself but remains free of ice and snow simply from the unique characteristics of the heating concept. What this means for the user is that the heating efficiency is as high as possible while keeping the power requirements down to an absolute minimum simply by good design.

The heating is regulated by temperature and is user selectable for one of three states (always on, always off and temperature controlled).

The USA-2 Wind Horizon 2-axis ultrasonic anemometers from Biral use the same time proven heating concept above but on a 2-axis head design.
