Campbell Scientific TDR100 System Specification

The Campbell Scientific TDR100 System is a sophisticated Time Domain Reflectometry (TDR) device designed for precise soil moisture and electrical conductivity measurements. It operates by generating a fast-rise step pulse, which is transmitted along a coaxial cable to a probe inserted into the soil. The system measures the time taken for the pulse to reflect back, allowing calculation of soil dielectric constant and, subsequently, soil moisture content. The TDR100 features a robust design capable of operating in a wide range of environmental conditions, making it suitable for both field and laboratory applications.

Key technical specifications include a measurement range of 0 to 7 ns with a resolution of 12 ps, providing high accuracy in dielectric constant determination. The system supports a variety of probe configurations, accommodating different soil types and measurement depths. It interfaces seamlessly with Campbell Scientific dataloggers, utilizing a CSI bus for efficient data handling and integration into broader environmental monitoring systems. The TDR100 is powered by a 12 V source, ensuring compatibility with standard field power supplies, and it boasts low power consumption, which is critical for remote, long-term deployments.

The system's modular design allows for easy maintenance and component replacement, enhancing its longevity and adaptability to new research needs. Data output is compatible with Campbell Scientific's PC-based software, enabling advanced data analysis and visualization. With its combination of precision, durability, and ease of integration, the TDR100 is an ideal solution for researchers and professionals focused on soil science, agricultural management, and environmental monitoring.
