Campbell Scientific CS475A Sensor Specification

The Campbell Scientific CS475A is a radar-based water level sensor designed for precise monitoring in hydrological and environmental applications. This non-contact sensor utilizes a 26 GHz radar, providing highly accurate measurements of water levels by emitting microwave signals and analyzing the frequency shift of the reflected waves. Its measurement range extends up to 70 meters, making it suitable for a wide variety of water bodies, including rivers, lakes, and reservoirs.

The CS475A features a compact and robust design, capable of withstanding harsh environmental conditions, thanks to its IP67-rated housing, which ensures protection against dust and water ingress. It operates efficiently in temperatures ranging from -40°C to 80°C, ensuring reliability in diverse climatic conditions. The sensor is equipped with a 4-20 mA current loop output, facilitating seamless integration with data loggers and SCADA systems, and supports HART protocol for advanced diagnostics and configuration.

Installation of the CS475A is straightforward due to its lightweight design and versatile mounting options, allowing it to be deployed in various settings, from bridges to docks. The sensor requires minimal maintenance, with no moving parts and a contact-free measurement approach, reducing the risk of mechanical wear and minimizing downtime.

Moreover, the CS475A is powered by a low-energy design, making it suitable for remote and off-grid sites where power conservation is critical. This sensor offers exceptional accuracy and reliability while providing real-time data crucial for effective water resource management, flood warning systems, and environmental monitoring projects. Its advanced radar technology ensures high performance even in challenging conditions, such as high turbulence or dense vegetation.
