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.
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.
| Parameter | Specification |
|---|---|
| Manufacturer / reference | Sato / 7980-S-40 |
| Measurement principle | Tipping bucket |
| Construction | Stainless steel |
| Collector orifice | 200 mm diameter |
| Rainfall increment | 0.5 mm per tip |
| Switch | Reed switch; listed contact time of 0.1 second |
| Listed accuracy | Within 2% at a rainfall intensity of 100 mm/hour |
| Height | 450 mm |
| Weight | 2.2 kg |
Specification note: These figures apply to the listed 7980-S-40 version. Confirm the supplied model and electrical contact limits before connecting it to existing equipment.
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.
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.
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.
Contact us for pricing and availability. Please include the quantity, installation location, required recording interval, recorder or counter model, cable length and any alarm or reporting requirements. For replacement enquiries, include the complete existing sensor reference.

Monnit ALTA Soil Moisture Sensor measures soil moisture tension & soil temperature within the soil. It uses a resistive granular matrix element to accurately measure the matric water potential (soil moisture tension) in the soil and a thermistor based temperature element to measure temperature.
- Safe to use in both hot & freezing temperatures
- Reports matric potential (soil water tension)
- Moisture readings in centibar & kPa
- 0 to 240 centibar (kPA)
- Will not dissolve in soil
- Internally compensated for commonly found salinity levels
- Easy to install and use compared to traditional tensiometers
- Stainless steel electrodes
- No maintenance required
- Temperature readings in C/F.
- 5 ft removable lead
Sato Refractometer SK100R, SK200R series measures liquid content by determining the refractive index of the liquid, based on the principle of total internal reflection.
Sekonic Universal 6 channel Recorder SP-100 / SP100 records from different sources simultaneously, including mA, V, PT100, Thermocouple.
Installation of the Tokico emergency shutoff valve is required at various industrial equipments by the High Pressure Gas Safety Law and the Fire Defense Law.
In the MB series of emergency shutoff valve, CO2 gas cartridge with high initial torque is adopted as drive source, and ball valve making smooth movement is adopted at the valve part.
It shutoffs urgently or opens the pipelines of various fluids and is most suitable as safety disaster prevention equipment which prevents second disaster from occurring.
Start a countdown without pressing a button with the Sato TM-27 and TM-29 non-contact timers. Hold your hand over the sensor to begin timing, making them practical for handwashing stations, food preparation areas and repetitive workstation tasks.
The KOFLOC 6800 series regulates pressure on the upstream side of a gas system by releasing gas when pressure exceeds the selected setting. Its compact design suits panel-mounted equipment and tank pressure control.
Monnit ALTA Wireless Carbon Dioxide Sensor uses an ultra low-power, high-performance CO2 sensor to measure the amount of carbon dioxide in ambient air.
- Measures 0 to 10000 ppm CO2
- Accurate to +/- 45 ppm + 3% of reading
- Sensor produces instantaneous CO2 readings and 8 hour time weighted average(TWA) readings
