Signal digital anemometer ASC-R

It is a measuring instrument. Registered in GOSREESTR (FGIS "ARSHIN"). It is designed to measure the speed of air flow (wind) in industrial conditions, to determine the limiting wind speed and to switch on the sound signal.
Measuring range of air flow (wind) speed, m/s: from 3.0 to 25.0;
Anemometer error tolerance limits: ±(0.5+0.05V) m/s, where V is the air flow (wind) velocity;
The control unit provides digital indication of air flow (wind) velocity with a discreteness of 0.1 m/s;
Number of digits of the digital display: 3;
Built-in sound signalling of the thresholds "ATTENTION" (V=7.5 m/s) and "DANGER" (V>Vpr) is provided, carried out by intermittent and continuous sound signal respectively;
The anemometer is electrically powered by two galvanic cells of type 373;
Power supply voltage, V:3.
