Sato 7980-S-40 Tipping Bucket Rainfall Sensor
The Sato 7980-S-40 tipping bucket rainfall sensor converts collected rainfall into electrical contact pulses for a compatible external recorder or counter. Its stainless steel construction and two-wire connection suit installations requiring rainfall measurement at a separate monitoring point.
- Rainfall resolution: 0.5 mm per bucket tip.
- Collector opening: 200 mm diameter.
- Signal: Reed-switch contact output.
- System connection: Two-conductor cable to compatible receiving equipment.
Build a rainfall recording system around the Sato 7980-S-40 tipping bucket rain gauge. The sensor produces a contact signal as the bucket tips, allowing compatible receiving equipment to count rainfall increments and maintain a record of accumulated precipitation.
When specifying a new installation or replacing an existing sensor, match the rainfall increment and contact characteristics to the recorder input. The sensor is one part of the measurement system; display, storage and reporting functions depend on the connected equipment.

Connecting to a rainfall recorder or counter
Choose receiving equipment that accepts the sensor’s contact signal and supports the correct rainfall scaling. For this configuration, each counted tip represents 0.5 mm of rainfall.
- Total rainfall: Configure the counter to convert accumulated tips into millimetres.
- Rainfall history: Specify a recorder or logger that stores counts over the required time intervals.
- Rainfall intensity: Confirm that the receiving system can calculate a rate from rainfall accumulated over time.
- Alarm requirements: State the rainfall threshold and time period if an external alarm function is required.
Provide the recorder model, input specification and proposed cable length when requesting a system quotation. A temperature-only logger should not be assumed to accept rainfall contact pulses.
Replacing an existing rainfall sensor
Send a photograph of the sensor nameplate and the connected recorder. Include the existing rainfall increment, wiring details and mounting dimensions so compatibility can be reviewed before a replacement is selected.
Where rainfall forms part of a wider weather monitoring project, you can also review the Sato three-cup wind speed sensor. Each measurement channel requires a compatible input arrangement.
