Convert the 40C anemometer from AC sine wave to logic level or voltage, to match the specific requirements of your system.

Interface Speed Amp 892E

The 892 Speed Amp interface converts the AC sine wave signal produced by the NRG 40C Anemometer (or any sensor with a compatible output) to a high-level, square wave signal.
This high-level signal is compatible with many data acquisition systems with frequency input capabilities. The 892 Speed Amp’s low power consumption makes it ideal for use with battery-powered data acquisition systems.

Interface SI5100

The SI5100 wind speed interface module is used for interfacing the NRG 40C Anemometer to an analog device such as a computer, meter, or recorder.
The module output signal is a negative ground voltage set at 0 to 5 VDC at wind speeds ranging from 0 to 44.7 m/s (0 to 100 mph).
Power is supplied by any 12 VDC source. The SI5100 is packaged in a plastic case with an octal plug. A DIN-rail mountable octal socket with screw terminals is included.
