Brief introduction: The instrument is widely used in hydrological telemetry system, most of the domestic system adopts the instrument as a rain sensor, so far, using the number has reached more than 5000 sets. Practice has proved that using the resolution of 1 mm DY1090A telemetry rainfall sensor type, can not only meet the requirements of flood control and disaster relief system, timely and accurate monitoring area rainfall regime, but also avoid unnecessary power consumption for additional increase in system, easy to reduce system configuration capacity of the battery. The instrument is stable performance, high reliability, because the structure of single skip, rainfall intensity and accuracy of measurement is a linear relationship, making it easy for users to the site installation and debugging. The instrument skip key parts made from metal, long-term field work is not easy to deformation, aging anti-static dust, ensure the long-term stability of the measurement precision. Technical indicators: The rain diameter: 200 mm Ф The blade Angle: 40 ~ 45 Resolution: 1 mm Working environment: ambient temperature: 0 ~ 50 Relative humidity: unlimited (50) Storage temperature range: - 40 ~ 60 Humidity storage range: 95% RH (50) Mode of transmission: can be chosen according to different user terminal lines: DY1090A1: single contact on-off output DY1090A2: double contact the transformation output (normal double break) DY1090A3: double contact the transformation output (normal 1 a) Rainfall intensity range: 0.01 ~ 4 mm/min (allowed by the heavy rain intensity 8 mm/min) Accuracy: 3% (the instrument itself displacement shall prevail, indoor artificial simulated rainfall as assessment method)
