Optical Level Switch
FineTek's micro photoelectric liquid level sensor features an ultra-low power circuit design, with all electronic components compliant with lead-free RoHS standards. This design employs low-power infrared emission and reception technology for precise measurements, combined with a high-precision ground quartz optical tip that is completely unaffected by the characteristics of acidic, high-viscosity, and high-turbidity liquid media. Additionally, it is resilient against environmental factors such as vibrations, frequent temperature changes, condensation, and dew. Its no-moving-parts and miniaturized design make it particularly suitable for installation in confined spaces while maintaining excellent measurement performance. It is ideal for applications in AI server cabinets' liquid cooling systems, immersion-type single-phase or two-phase cooling systems, as well as liquid level protection in coolant distribution manifolds (CDM) and coolant distribution units (CDU) within server cabinets.
As AI servers continue to upgrade their CPU and GPU specifications, the complexity of computations leads to significant increases in operating temperatures, rendering traditional fan-based air cooling ineffective. Advances in next-generation water cooling technology have improved power usage efficiency (PUE) from 1.5-1.7 in air-cooled systems to 1.1-1.2, successfully reducing air conditioning energy consumption. In this process, FineTek's micro photoelectric liquid level sensor plays a crucial role by continuously monitoring the coolant level for abnormalities, ensuring that the cooling process operates normally and becoming a key driver for AI servers to achieve energy savings and carbon reduction while pursuing high-speed computing.
This product has obtained North American UL safety certification, and FineTek is one of the few companies capable of providing MTBF (Mean Time Between Failures) reliability validation during the development phase, along with extensive customization design and production services. As a manufacturer with industrial-grade sensor design experience and expertise, FineTek is an indispensable supplier of high-precision sensors in green computing applications.
