However, for the highest accuracy, the characteristic transfer function should be used to compensate for starting inertia. [. . . ] The WHP151 power supply provides the operating and heating power needed for the WA15. The power supply, as well as the signal and power cables are available as options. Anemometer with excellent linearity The WAA151 is a fast response, low-threshold anemometer. Three lightweight, conical cups mounted on the cup wheel, provide excellent linearity over the entire operating range, up to 75 m/s. A wind-rotated chopper disc attached to the shaft of the cup wheel cuts an infrared light beam 14 times Technical data Vaisala Wind Set WA15 Options and accessories Crossarm and termination box 16-lead signal cable 6-lead power cable Crossarm and analog transmitter 6-lead cable for signal and power Crossarm and serial RS485 transmitter Serial RS485 transmitter card Power supply Set of bearings and gasket Cup assembly Tail assembly WAC151 ZZ45048 ZZ45049 WAT12 ZZ45049 WAC155 WAC155CB WHP151 16644WA 7150WA 6389WA Features/Benefits High-performance wind measurement set Long and successful track record in meteorological applications Accurate wind speed and direction measurement Low measurement starting threshold Conical anemometer cups provide excellent linearity Heated shaft prevents bearings from freezing Technical data Vaisala Anemometer WAA151 Wind speed Measurement range 0. 4 . . . 75 m/s Starting threshold < 0. 5 m/s * Distance constant 2. 0 m Characteristic transfer function U = 0. 328 + 0. 101 × R (where U = wind speed [m/s], R = output pulse rate [Hz]) Accuracy (within range 0. 4 . . . 60 m/s) with characteristic transfer function ± 0. 17 m/s ** with transfer function U = 0. 1 × R ± 0. 5 m/s*** Vaisala Wind Vane WAV151 Wind direction Measurement range at wind speed 0. 4 . . . 75 m/s Starting threshold Resolution Damping ratio Overshoot ratio Delay distance Accuracy 0 . . . 360° <0. 4 m/s ±2. 8° 0. 19 0. 55 0. 4 m better than ±3° General Operating power supply Uin = 9. 5 . . . 15. 5 VDC, 20 mA typical Heating power supply AC or DC 20 V, 500 mA nominal Output 0 . . . 750 Hz square wave Transducer output level high state > Uin-1. 5 V with Iout < +5 mA low state < 2. 0 V with Iout > ­5 mA Settling time after power turn-on < 30 µs Plug 6-PIN MIL-C-26482 type Cabling 6-wire cable through crossarm Recommended connector at cable end SOURIAU MS3116F10-6P Operating temperature with heating -50 . . . +158 °F) Material housing AlMgSi, grey anodized cups PA, reinforced with carbon fibre Dimensions 240 (h) × 90 (Ø) mm Swept radius of cup wheel 91 mm Weight 570 g General Operating power supply Uin = 9. 5 . . . 15. 5 VDC, 20 mA typical Heating power supply AC or DC 20 V, 500 mA nominal Output code 6-bit parallel GRAY Output levels high state > Uin ­1. 5 V With Iout < +5 mA low state < 1. 5 V With Iout > ­5 mA Settling time after power turn-on < 100 µs Plug 10-PIN MIL-C-26482 type Cabling 10-wire cable through crossarm Recommended connector at cable end SOURIAU MS3116F12-10P Operating temperature with heating -50 . . .
