To
continuously monitor the angle of tilt of the anemometer sonic was
installed on the cradle of the anemometer itself a semiconductor
inclinometer (model FAS-A, microstrain). The tool is able to detect oscillations up to a frequency of 30 Hz, which is the angle of pitch angle of roll.
The
inclinometer FAS-A is based on the use of two accelerometers made of a
semiconductor and then integrated in the same chip, appropriately
coordinated by a microprocessor (with A / D conversion, 12-bit),
whereby you can have both a amplified
signal voltage proportional to tilt towards the Earth's gravity vector,
that of a digital signal on serial port RS232. The
inclinometer is capable of measuring 360 degrees of tilt on a single
axis (typically pitch), or it can detect ± 70 ° tilt on two axes (roll
and pitch), with an angular resolution of 0.1 °. The
operating mode (eg single or double axle), and its parameters (eg any
filters) can be programmed by the user and stored on board
dell'inclinometro on non-volatile memory (EEPROM). The instrument is fed continuously with voltage between 5V and 12V.
