It is also possible to measure low water levels of 30cmH2O! There is also an explosion-proof type available.

The water level gauge series 46X is a low-level water gauge that uses a ceramic sensor element, capable of measuring water levels from 0 to 30 cmH2O. By performing mathematical correction processing on a microprocessor digital circuit, it achieves an accuracy of ±0.1% FS. In addition to a digital RS485 interface, it also features an analog output, allowing for scaling settings (changing the water level range). An intrinsically safe explosion-proof type 46XEi is also available. 【Features】 〇 Utilizes a capacitive method. The ceramic sensor element is suitable for low-pressure measurement. 〇 Standard equipped with both digital RS485 and analog outputs. 〇 Digital correction of output signals. 〇 Explosion-proof type available (41XEi).

In civil engineering sites, the use of sheet piling methods is essential for safely utilizing the site, including temporary roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates have been widely used, but due to their weight, they can be cumbersome to transport, install, and remove. Hyper CLT sheet piles are civil engineering materials made from wooden CLT for civil use. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle with small machinery, contributing to reduced burdens during installation and improved work efficiency. They can be utilized in a wide range of civil engineering sites for measures against muddy conditions, ground protection, heavy machinery scaffolding, and ensuring pedestrian pathways. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A," it is also recommended as a material for innovative ideas, safety measures, and environmental considerations in public works.

In civil engineering sites, there are many instances where temporary roads, access routes, heavy machinery workspaces, and material storage areas use ground plates. Traditional steel plates are heavy, requiring large machinery for installation and removal, which can make work difficult in narrow sites. Hyper CLT ground plates are lightweight civil engineering CLT materials made from wooden CLT for civil use. A 5×10 plate weighs about 230 kg, and a 5×20 plate weighs about 460 kg, making them easy to handle even with small machinery, thus reducing the burden of transportation, installation, and removal. They are easy to use in sites with limited space or where the use of large machinery is difficult. They can be widely used for temporary roads, heavy machinery scaffolding, pathways within the site, and material storage protection, contributing to glare reduction, noise reduction, and environmental consideration. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," they are also recommended as materials for innovative ideas and safety measures in public works.
