In the design of the Water Cube, a key decision was made to incorporate hollow glass bricks due to their ideal balance of functionality and sustainability, aligning perfectly with the "Green Olympics" initiative. This eco-friendly building material was chosen early in the planning stage. During the bidding process for the Water Cube project, three companies were initially considered: Zhenhua Decorative Glass Co., Ltd. (Jinghua Glass Brick) from Shandong Dezhou Jinghua Group, Hebei Jihengyuan Industrial Group Co., Ltd. (Haiwei Glass Brick), and Witt Company. Additionally, Shanghai Xinghu Company was also involved but later discontinued. However, the Water Cube required a less common size—2480 (240×240×80mm)—rather than the traditional 1980 type (190×190×80mm). As a result, the latter two companies struggled to produce this specific size and were eventually eliminated from the competition. In contrast, the Texas Jinghua Group quickly adapted by investing in technical upgrades within just two months, successfully developing both brick and corner brick products. This effort allowed them to outperform their competitors, including Italy's Witt Company, and ultimately win the bid. According to staff from Zhenhua Decorative Glass Co., Ltd. under the Jinghua Group, hollow glass bricks are well-suited for indoor applications such as bathroom partitions, room dividers, porches, and functional walls that require natural lighting, sound insulation, and thermal efficiency. These bricks not only enhance the aesthetic appeal of spaces like living rooms but also fulfill essential practical functions. They are considered a rare and versatile decorative material. In recent years, large-scale glass brick walls have gained popularity for outdoor use, particularly in areas where lighting and insulation are important. These materials are now widely recognized and appreciated in various public buildings, including banks, office complexes, hospitals, schools, hotels, airports, train stations, and landscape designs. Their unique combination of beauty and utility has made them a preferred choice for modern architectural projects.

Conductivity Probe How It Works

Overview

Conductivity probes, also known as conductivity sensors or conductivity detectors, are indispensable tools in various industries for measuring the electrical conductivity of solutions. These devices are crucial for understanding and monitoring the composition and purity of liquids. Electrical conductivity (EC) is usually measured in units of Siemens (S)/distance. When the number of dissolved ions (charged particles) in a solution increases, the solution's ability to carry an electric charge also increases. The sensor probe can sense the ability of positively and negatively conductive ions to measure the conductivity of the solution.

Operating Principle

The operating principle of a conductivity probe involves measuring the electrical current passing through a solution contained within a conductivity cell. An electric current is applied to the solution, and the magnitude of this current is then measured by a conductivity meter. Conductivity is calculated using the known geometry of the cell and the applied voltage.

Advanced probes, featuring a four-electrode design, offer enhanced accuracy and stability. This design often eliminates the need for pre-calibration, thereby simplifying the measurement process and providing more reliable results.

Applications

Conductivity probes have a wide range of applications across different fields. In environmental monitoring, they are used to detect water pollution by measuring the presence of ionic contaminants. This helps in identifying potential health hazards and ensuring that water bodies remain safe for human and wildlife consumption.

In water quality testing, conductivity probes monitor the conductivity of municipal water supplies and industrial processes. This ensures that water meets regulatory standards and is safe for consumption and use.

In the food processing industry, conductivity probes control the concentration of solutions to maintain consistent product quality. This is crucial for ensuring that food products meet safety standards and consumer expectations.

Furthermore, conductivity probes are essential in biomedical research for analyzing ion concentrations in biological samples. This aids in the understanding of physiological processes and diseases, contributing to advancements in medical science.

Maintenance Tips

Proper maintenance is crucial for ensuring the accuracy and longevity of conductivity probes. Regular cleaning of the electrodes prevents the accumulation of deposits that can interfere with measurements. This ensures that the probe remains in good working condition and provides accurate results.

Periodic recalibration using standard solutions is also essential. This ensures that the probe remains accurate over time and continues to provide reliable data. It is important to follow the manufacturer's instructions for recalibration to ensure the best results.

Additionally, verifying secure electrode connections is essential to prevent errors and ensure reliable data. Loose connections can cause measurement errors and affect the accuracy of the results. Therefore, it is important to regularly check and tighten electrode connections as needed.

In conclusion, conductivity probes are indispensable tools in various fields, from environmental monitoring to biomedical research. Understanding their operating principles, applications, and maintenance requirements is essential for ensuring accurate and reliable measurements. By following these guidelines, users can maximize the performance and lifespan of their conductivity probes.
