- Interface 40C to Logic Level, Speed Amp #892E
Interface 40C to Logic Level, Speed Amp #892E
Convert the 40C Anemometer from AC sine wave to square wave.
Details
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.
