Rain intensity sensor suitable for monitoring sudden rainfall such as guerrilla rainstorms!
The "OW-RFI-01" is a rain intensity sensor that integrates a rain intensity calculation unit into a tipping bucket rain gauge. You can set any desired rain intensity value as an alarm threshold. By utilizing the alarm contact output, you can control alarms and signal lights. 【Features】 ■ Adopts a tipping bucket rain gauge, eliminating the need for regular kerosene replacement. ■ Holds the 6-minute accumulated value for the next 6-minute sampling period, outputting a stepped analog signal of 0-100mm/h at 4-20mA. ■ Alarm settings can be configured via the internal setting switch. ■ Can also be used as a tipping bucket rain gauge with pulse output (optional). ■ The "OW-RFI-05" is also available, with a measurement range of 0-500mm/h and a minimum unit of 5mm/h. *For more details, please download the PDF or feel free to contact us.
