The Sato 7980-S-13 three-cup wind speed sensor provides an analogue wind-speed signal for a compatible display, recorder or monitoring system. Its rotating cup assembly drives an AC generator, with built-in DC conversion and linearisation to condition the output.

Use this page to specify a sensor for a new installation or identify the requirements for replacing an existing unit. The receiving instrument, cable arrangement and power supply must be matched to the selected sensor configuration.

Wind speed measurement and signal output

The three-cup assembly measures wind speed without measuring wind direction. A separate direction sensor or combined wind speed and direction instrument is required when both measurements are needed.

The standard voltage output can be used with a compatible analogue input. For a PLC, data logger or panel indicator, confirm the input range and scaling rather than assuming that any analogue input will accept the sensor directly.

Sensor specifications

Low-wind measurement: The output scale begins at zero, but the listed measuring range begins at 2 m/s. Do not interpret the zero-based output scale as confirmation of accurate measurement below the starting threshold.

Match the sensor to your monitoring equipment

RequirementWhat to confirm
Local wind-speed display Indicator input compatibility, engineering-unit scaling and sensor power supply.
Data logging Analogue input type, recording interval and whether instantaneous or averaged readings are required.
PLC connection Voltage or current input, wiring arrangement, signal common and configured measurement span.
Wind alarm Compatible alarm equipment, setpoint, averaging period and required alarm output.
Existing sensor replacement Full model code, output signal, supply voltage, cable termination and mounting dimensions.

Do not assume that the voltage and current outputs are both included or selectable on the same unit. Specify the required output when requesting a quotation.

Need wind direction as well?

For applications requiring both measurements, view the Sato wind speed and direction system. Confirm the complete sensor and indicator combination for the required installation.
