Windspeed Limited (Vector Instruments , VI) products

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.

This anemometer is a variant of the A100L2 which itself was originally developed from the proven A100 Porton™ instrument and R30 rotor design. This variant is offered to satisfy those low-power applications requiring an anemometer offering a pulse/frequency output while consuming little supply current and operating from a supply as low as 5v. The low power consumption, wide power supply range and pulse/frequency signal 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.

The A100R is an anemometer designed for `run of wind` or average wind speed measurements when used with an electronic counter or a data logger. The calibrated 3-cup R30 series rotor drives an actuator in a carefully balanced magnet system with the resulting varying field operating a reed switch (contact opens and closes once per rotor revolution). The reed switch is mercury-wetted which results in bounce-free operation. Note: Also consider our A100AC for an alternative anemometer model which is lower-cost, requires no power to operate, produces 2 pulses/revolution and does not contain mercury.
