The SandFlow SF4 sensor: an ultra-robust 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 two strong stainless steel arms.
Sand flux impact and wind laminar air friction induce change in internal acoustic pressure. The two excitations are discriminated as independent signals as a result of a specific acoustic, mechanical and electronic design.
You can customize the full configuration of the sensor, in a non-volatile memory, with a Plug-and-Play computer connection thanks to a universal USB dongle accessory.
