Campbell Scientific CS115 Sensor Specification

The Campbell Scientific CS115 Sensor is a sophisticated instrument designed for precise atmospheric research. This sensor specializes in measuring the potential gradient of the electric field in the atmosphere, which is essential for studies related to thunderstorms, lightning, and other meteorological phenomena. The CS115 operates efficiently in a wide range of environmental conditions, making it suitable for both field and laboratory studies.

The CS115 sensor utilizes a reciprocating shutter to alternately expose and shield its sensing electrode, thereby enabling accurate measurement of the atmospheric electric field. It features a robust and weather-resistant construction, ensuring durability and reliability in harsh environments. The sensor's design minimizes errors caused by wind, precipitation, and contaminants, thanks to its carefully engineered components.

The CS115 interfaces seamlessly with Campbell Scientific dataloggers, allowing for efficient data collection and analysis. It supports standard communication protocols, ensuring compatibility with a broad range of systems and simplifying integration into existing research setups. The sensor requires a stable power supply, typically provided by an external battery or solar panel, to maintain continuous operation.

Calibration and maintenance are straightforward, supported by comprehensive documentation and technical support from Campbell Scientific. The CS115 is versatile, able to function autonomously in remote locations or as part of a more extensive monitoring network. Its precision and reliability make it an invaluable tool for researchers and meteorologists seeking to understand and predict atmospheric electrical phenomena. The CS115's combination of advanced features, durability, and ease of use underscores its status as a leader in atmospheric electric field measurement technology.
