Metal Fusion Sight Glass Clinport(R)

Glass and metal are integrated, giving it an astonishing strength as a glass product.

The metal-fused sight glass, Clinport(R), is a product born from a revolutionary technology that powerfully and hermetically fuses special glass directly to the inner wall of a metal ring, while utilizing the difference in thermal expansion coefficients between the metal ring and the glass to enhance the glass. It has obtained patents in Japan and the United States, proving the uniqueness and excellence of its technology. Since the glass and metal are integrated, it possesses an astonishing strength for a glass product. Therefore, there is almost no concern about glass breakage. If the glass does break, the damage remains confined to the surface layer, appearing in thin, flake-like pieces, and the destruction progresses gradually, which prevents the contents from spilling out in the event of a breakage, thus earning high safety ratings. For more details, please contact us or refer to the catalog.

Transparent Water Surface Gauge (High Pressure Type)

High-pressure water level gauge! Numerous applications in marine main boilers and thermal power plant turbine systems.

The "Transparent Water Level Gauge (High Pressure Type)" is a top-grade water level gauge. It is highly rated for its stable performance and is widely used as a water level gauge for high-pressure water supply heaters, primarily in main boilers for ships and turbine systems for thermal power generation. By securing two gauge glasses with front and rear covers, the gauge glasses are not subjected to clamping force, resulting in a structure that reduces stress and is less prone to damage even under high temperature and high pressure. 【Features】 ■ Uses a special graphite packing as a sealing gasket to prevent damage and leakage of the gauge glass. ■ Equipped with a mica plate (muscovite) on the inside to protect the gauge glass from corrosion. ■ The visible direction of the water level gauge can be freely adjusted. ■ Utilizes energy-efficient LED lighting to prevent bulb failure due to ship vibrations. *For more details, please refer to the PDF materials or feel free to contact us.

【Installation method is flexible!】Pressure transmitter type liquid level gauge P series

Robustness type commonly used in applications with high humidity and significant vibrations, such as ships, due to factors like vibration, seawater resistance, high temperature and humidity, and intense liquid agitation.

The liquid pressure in the tank is detected by a diaphragm, and the capacitance changes as the distance between the two electrodes arranged in parallel inside changes. An analog signal of 4-20 mA is also output from the center, transmitting and displaying the liquid level in the tank to monitoring panels, etc. It is possible to provide not only the sensor but also a system that includes a display unit. <Features> ■ Compact size and robust structure make installation and maintenance easy. ■ The sensor part is protected, making the diaphragm less prone to damage. ■ Various mounting methods are available, allowing for adaptation to different installation environments. *For more details, please refer to the PDF materials or feel free to contact us.
