| A100L2 Low Power Anemometer (Analog+Pulse Outputs) |
| |
 |
This anemometer was developed from the proven A100 Porton™ instrument and R30 rotor design in response to demand for an anemometer offering pulse/frequency and analogue voltage outputs while consuming little supply current.
The low power consumption, wide power supply range and choice of pulse/frequency and analogue voltage output signals make this anemometer a popular choice for use with data loggers for applications such as general meteorology and wind-power site surveying as this instrument has first class performance.
A slotted disk interrupting a light beam is used to detect the motion of the calibrated R30 series 3-cup rotor and hence determine the wind speed. The internal electronics condition this pulse signal for output as a 5V squarewave and use it to generate an analogue voltage proportional to the wind speed.

Construction is from anodised aluminium alloys, stainless steels and weather resisting plastics for exposed parts. Precision corrosion resistant ball-races and a stainless steel shaft enable the R30 rotor response to produce a highly sensitive yet robust instrument suitable for continuous exposure to the weather.
Options for this anemometer include:/PC3 Anti-Surge protection/HE-4 Internal Anti-Icing Heater/HE-1 & /HE-2 External/Retrofit Anti-Icing Heaters/WR Marine Version
Note: /WR, /HE-1 and /HE-2 are not recommended for high precision applications.
The recommended mounting adaptors for use with this instrument are our type 405 and 405-1 series.
Vector Instruments A100L2 Anemometers are among the very few available having Class 1 performance ("First Class") according to the requirements of IEC and MEASNET standards.
