Feature: 1. SMOOTH AND CONVENIENT: The core component tipping bucket adopts a three dimensional design, which is more smooth, and has the function of self cleaning dust and easy cleaning. Pulse to 485 signal output, can directly read the rainfall, no need for secondary calculation, simple and convenient 2. INTEGRATED STRUCTURE: Consists of one piece shell, filter, funnel, reverse dump bucket, wiring terminal, outrigger bracket, dry reed switch, control box, rain gauge base, etc. Among them, the tipping bucket shaft and the base of the circular rain gauge are equipped with a horizontal bubble, a reed switch bracket and a signal output terminal, the tipping bucket bushing is an integrated positioning structure, and the tipping bucket is installed in the bearing through the tipping bucket shaft 3. EASE OF MAINTENANCE: The tipping bucket is a three dimensional streamlined design with a drooping curved deflector tip. Beautiful and smooth appearance, good tipping performance, easy to clean and maintain 4. GOOD DEBUGGING: The tipping bucket is made of permanent magnet steel, and the reed switch is installed on the reed switch bracket. When leaving the factory, both the magnetic steel and the reed switch have been adjusted to the appropriate coupling distance, so that the output signal of the instrument has a certain proportional relationship with the number of times the tipping bucket is turned over. 5. WIDE APPLICATION: Can be used in relevant departments such as meteorological stations, hydrological stations, agriculture and forestry, national defense, field observation and reporting stations, etc., can be used with rain recorders to measure precipitation, precipitation strength, precipitation time, etc., also can be used for flood control, water supply scheduling, power station reservoir water information management to provide data Specification: Item Type: Rainfall Sensor Material: Magnetic steel Rain Bearing Diameter: Approx. 200mm / 7.87in Of Sharpness Cutting Edge: 40°-45° Resolution: 0.2mm Measurement Error: ≤±3% Rain Strength Range: 0mm～4mm/min (maximum allowable rain strength 8mm/min) Communication Method: 485 Communication (standard protocol) Maximum Power Consumption: 0.24W Working Environment: Ambient Temperature: 0-50℃ Relative humidity: <95%(40℃) Power supply range: 4.5~30V. Package List: 1 x Rain Sensor1 x Accessory (Random)3 x Screw3 x Wall Plug Note: 1. The instrument has been outdoors for a long time, and the operating environment is very harsh. Therefore, always use a soft cloth to wipe the inner wall of the rain shield of the instrument to keep the rain shield clean.2. If there are foreign objects such as leaves in the rain outlet, it should be cleaned up in time to keep the waterway unblocked.3. When the instrument is not used for a long time, cover the ring mouth of the instrument to protect the rain shield.4. It is recommended to clean the instrument once a month for long term work, and once every three months.
