SISCO industrial tipping bucket rain sensor is built with a corrosion-resistant stainless steel housing for long-term durability. The rainfall detection sensor requires minimal maintenance and performs reliably in harsh weather, delivering consistent data for professional environmental monitoring.
Precision Tipping Bucket Delivers Reliable Rainfall Data
- Adopts a precision-engineered tipping mechanism that triggers with each precise volume of rainfall (typically 0.1mm or 0.2mm per tip) for consistent measurement.
- Utilizes imported dry reed switches and magnetic steel to generate stable pulse signals with every bucket tip, ensuring reliable data output.
- Features a 200mm diameter stainless steel orifice with a built-in filter screen to prevent debris ingress while maintaining measurement accuracy.
- Incorporates a precision bearing pivot and bubble level for easy on-site calibration, minimizing installation errors and maximizing long-term measurement consistency.
304 Stainless Steel Housing Ensures Long-Term Durability
- Offers superior corrosion resistance against rain, humidity, and chemical exposure, ensuring a service life far exceeding plastic alternatives.
- Features a fully sealed housing that protects internal components from dust, moisture, and insect intrusion, reducing maintenance needs.
- Maintains structural integrity across a wide temperature range, preventing warping or degradation that could affect measurement accuracy.
- Supports flexible installation options with a 3-meter mast and adjustable brackets, providing stable mounting even in high-wind or uneven terrains.

Dimensional Drawing (unit: mm)
Q1: How does the industrial tipping bucket rain sensor measure rainfall accurately?
A1: This industrial tipping bucket rain sensor, 304SS, utilizes a precision-engineered tipping mechanism for accurate rainfall measurement. Each time the bucket collects 0.2mm of precipitation, it tips and triggers a dry reed switch to generate a stable pulse signal. The rainfall detection sensor then outputs data via Modbus-485, ensuring precise real-time monitoring.
Q2: What maintenance does the 304SS rainfall sensor require for long-term outdoor use?
A2: Built with a corrosion-resistant stainless steel housing, the industrial tipping bucket rain sensor, 304SS, requires minimal maintenance. Regular checks include cleaning the 200mm filter screen to remove debris, inspecting the tipping bucket for smooth operation, and ensuring the bubble level remains centered. With proper care, this rain gauge sensor delivers reliable performance for years in harsh environments.
Q3: What power and output options are available for this rain gauge sensor?
A3: Operating on DC12V with ultra-low power consumption of only 0.02W, this industrial tipping bucket rain sensor, 304SS, is ideal for solar-powered remote installations. The rainfall detector supports RS485 Modbus output, enabling seamless integration with PLCs, data loggers, and SCADA systems for professional monitoring applications.
Tips: What are the common installation mistakes to avoid with this rainfall sensor?
- Mounting the sensor on an uneven surface is a frequent error. Always use the built-in bubble level during installation. An unlevel rain gauge sensor can cause water to drain unevenly, leading to undercounting or overcounting of rainfall. Adjust the mounting bracket until the bubble is perfectly centered.
- Forgetting to remove the protective cover from the orifice before operation is another common oversight. The 200mm opening must remain unobstructed to allow water to enter freely. Also, ensure the filter screen is properly seated to block debris while permitting smooth water flow into the tipping bucket.
- Installing the sensor near obstructions such as trees or building edges can create wind turbulence that affects rainfall capture. Position the rain gauge sensor in an open area, with the orifice at least 1.5 times the height of any nearby obstruction, to ensure representative samples.
- Neglecting to test the output after installation can lead to undetected wiring or configuration issues. Connect this rainfall detection sensor to your data logger and verify the Modbus-485 signal before relying on the data. A quick functionality check saves time and prevents data loss during the first rain event.
