Campbell Scientific CS140 Sensor Specification

The Campbell Scientific CS140 Sensor is a sophisticated instrument designed for precise and reliable visibility measurement across various environmental conditions. Primarily employed in meteorological stations, airports, and road monitoring systems, the CS140 stands out for its ability to accurately measure visibility in the range of 10 to 75,000 meters. The sensor operates using forward scatter technology, which involves projecting a beam of infrared light into the atmosphere and analyzing the scattered light to determine visibility levels. This technology ensures high accuracy and reliability, even in challenging weather conditions such as fog, rain, or snow.

The CS140 is equipped with advanced self-diagnostic capabilities, enhancing its operational reliability by constantly monitoring its own performance and alerting users to any malfunctions or necessary maintenance. The sensor is also designed to minimize maintenance requirements, featuring a durable construction that withstands harsh environmental conditions. It includes an integrated hood heater that prevents the accumulation of snow and ice, ensuring consistent performance in cold climates.

Connectivity and data integration are facilitated through multiple communication options, including RS-232, RS-485, and SDI-12 interfaces, allowing seamless integration into existing meteorological or transportation management systems. The sensor supports remote configuration and data retrieval, enhancing its adaptability in various deployment scenarios. Operating efficiently with a low power consumption profile, the CS140 is suitable for remote or solar-powered installations. With its robust performance, ease of integration, and minimal maintenance requirements, the Campbell Scientific CS140 Sensor is an ideal choice for professionals seeking accurate and dependable visibility measurement solutions in diverse environments.
