Cup anemometer 454 series

for marine applications

For weather observers, amateur meteorologists and yachtsmen, the yacht anemometer is the ideal instrument for measuring wind speed. Its robust sensor design and splash-water protected indicating instrument render the yacht anemometer suitable for using also under harsh environmental conditions. As the instrument requires no supply and is simple to install, it can be placed in operation quickly and without complications. Product range: Anemometer measuring range 0 ... 100 km/h Anemometer measuring range 0 ... 100 km/h with additionally sealed indicator. with range expanding kit: Anemometer measuring range 0 ... 200 km/h Anemometer measuring range 0 ... 200 km/h with additionally sealed indicator. Measuring principle: The cup star vane rotates at a speed proportional to wind speed and drives the alternating current generator. The current produced is supplied via a 2-core cable to the indicator which displays the speed in km/h, knots and Beaufort. As the alternating current generator produces current independently, the measuring system requires no further supply. Optionally available: Measuring range expanding kit up to 200 km/h, comprising a changeover switch (×2) and a balanced ballast resistor (the complete system is required for the adjustment).
