SISCO stainless steel tipping bucket rain sensor features a 200mm diameter orifice with 40°-45° sharp-edged rim. Hard-alloy bearings reduce friction for extended durability. Dual reed switches ensure stable signal output under varied rainfall intensities. All exposed components utilize corrosion-resistant stainless steel construction.

Multi-Resolution Selectable for Varied Accuracy Demands

Three Output Options for Broad System Compatibility
SISCO stainless steel tipping bucket rain sensor is widely used for liquid precipitation measurement in meteorological observation networks, hydrological monitoring stations, agricultural irrigation scheduling, and urban drainage early warning systems.

Q1: What is the accuracy of this stainless steel tipping bucket rain sensor?
A1: The measurement accuracy is ≤±4% based on indoor artificial precipitation tests using the instrument's own displacement as a reference. This ensures reliable data collection for most meteorological and hydrological applications.
Q2: How do I choose between 0.1mm, 0.2 mm, and 0.5mm resolution for this rain sensor?
A2: 0.1mm resolution captures fine precipitation events for high-precision monitoring; 0.2mm is the default setting balancing accuracy and data load for general use; 0.5mm reduces data transmission frequency, ideal for long-term unattended operation.
Q3: What output signals does this stainless steel tipping bucket rain sensor support?
A3: This sensor is available with three output options: RS485 (Modbus-RTU) for digital system integration, analog (4-20mA or 0-10V) for traditional controllers, and pulse for retrofitting older counting instruments. You can select the appropriate version based on your existing data acquisition system.
