CUPPED TACHO-ANEMOMETERS
Wind speed sensor
The tacho-anemometer is a sensor for measuring wind speed. It comprised a light alloy transducer protected by polyurethane paint. The tachymetric system is fitted inside. This consist of a seventy-two notch rotating disc with optoelectronic reading. The electrical signal is made up of a series of pulses with frequencies that are proportional to the speed of the rotor fitted on the sensor transducer. In the heated versions, a thermostat controls a heater that keeps the rotor moving effectiveley in case of freezing. The sensor range includes versions with "normalised" and with "direct" outputs. Sensor with "direct" output can be used, without the addition of signal conversion units, together with LASTEM acquisition systems. The sensor transducer (see "Versions"), rotor (code DNA007) and connection cable (see "Accessories") must be included in the supply.
