Product Description:

The WindFlow WF4 sensor is an unbreakable hurricane-resistant wind-speed instrument.

It is a very low-power, maintenance-free and totally sealed acoustic instrument with no mobile parts.

The instrument includes a dedicated analog conditioning module, a digital I/O module and an analog restitution module that can be connected conveniently to almost any external central unit (data logger, industrial module interface, instrumentation DAQ, USB port).

The sensing part of the instrument is a cylindrical, anti-abrasion, anti-adhesion and anti-rime coated tube supported by one strong stainless steel arm.

Wind laminar air friction induces change in internal acoustic pressure. The excitation is converted into a wind speed signal as a result of a specific acoustic, mechanical and electronic design.

The configuration of the sensor can be fully customized, in a non-volatile memory, with a Plug-and-Play computer connection thanks to a universal USB dongle accessory provided with the sensor.
