Campbell Scientific PCRC-11 Sensor Specification

The Campbell Scientific PCRC-11 Sensor is a precision instrument designed for accurate measurement of precipitation. Engineered for both reliability and durability, the PCRC-11 is ideal for a wide range of meteorological and hydrological applications. This sensor operates on the principle of a tipping bucket mechanism, which is highly effective in capturing and quantifying rain events. The bucket tips with each incremental volume of precipitation, ensuring precise data collection with a resolution typically set to 0.1 mm per tip.

Constructed with high-grade materials, the PCRC-11 is resistant to corrosion and environmental wear, making it suitable for long-term outdoor deployment. Its aerodynamic shape minimizes wind effects, thereby enhancing measurement accuracy. The sensor features a robust design that includes a funnel and reed switch, which are integral to its operation. The reed switch is a critical component, providing a reliable electrical signal each time the bucket tips.

The PCRC-11 can operate effectively in a wide temperature range, ensuring consistent performance under varying environmental conditions. It is compatible with Campbell Scientific dataloggers, which allows seamless integration into existing data acquisition systems. The sensor requires minimal maintenance, attributed to its simplistic mechanical design, which reduces the risk of mechanical failure.

Installation of the PCRC-11 is straightforward, with mounting options that allow for flexibility in deployment. The sensor's connectivity options facilitate easy data transmission for remote monitoring. Overall, the Campbell Scientific PCRC-11 offers a combination of accuracy, durability, and ease of use, making it a trusted choice for professionals in meteorological research and environmental monitoring.
