德國Sommer SPA積雪特性分析儀
產品概述
德國Sommer SPA積雪特性分析儀是一款用于連續監測雪水特征的先進系統。該系統采用革命性技術，可實時測量雪水當量、雪密度、雪深度以及雪中冰和水含量等關鍵參數。SPA系統由SPA傳感器（又稱雪水傳感器SWS）、阻抗分析盒和雪深傳感器組成，能夠為水文研究、雪崩預警和水資源管理等領域提供重要數據支持。56
技術原理
該設備基于高頻介電常數測量原理，通過扁平線狀傳感器測量雪層中冰、水、空氣三相介電常數的差異，從而計算出雪密度和液態水含量。系統支持安裝1-4個傳感器，每個傳感器長度5-6米，采用耐熱抗UV材料制成，內置三條寬銅線。獨特的多傳感器配置方案可實現不同深度的雪密度廓線測量，大幅提升觀測數據的代表性和準確性。519
應用功能
SPA系統特別適用于長期原位觀測，能連續監測積雪層中液態水含量的動態變化。在春季融雪期，可及時監測積雪飽和狀態，為洪水預警和雪崩防范提供關鍵依據。系統采用低功耗設計，睡眠模式電流僅2mA，非常適合太陽能供電的野外監測站點使用。測量數據可通過RS-232接口輸出ASCII格式，便于集成到各類環境監測系統中。711
Product Introduction
The Sommer SPA Snow Pack Analyzer from Germany is an innovative monitoring system designed for continuous measurement of snowpack characteristics. This system utilizes high-frequency dielectric measurement technology to accurately determine snow water equivalent, snow density, snow depth, and ice/liquid water content in snow layers. The modular design includes flat ribbon sensors, impedance analysis units, and snow depth sensors. 820
Technical Features
With its unique multi-sensor configuration (supporting 1-4 sensors), the SPA system can measure snow density profiles at different depths. The 5-6 meter long sensors feature UV-resistant materials and three embedded copper strips for precise dielectric measurements. The system operates efficiently with low power consumption (50mA during operation, 2mA in sleep mode), making it ideal for remote solar-powered stations. Data output is provided in standard ASCII format via RS-232 interface. 1927
Applications
This analyzer is particularly valuable for hydrological research, avalanche forecasting, and water resource management. Its continuous monitoring capability provides early warnings of snowmelt processes and flood risks. The system s robust design ensures reliable performance in harsh winter environments, delivering critical data for snowpack analysis and climate studies. Various configurations are available to meet different observation requirements in alpine regions, watersheds, and research sites. 1129
