Product Introduction
The Shenzhen SKAA2 intelligent oil micro-water sensor from Shenzhen Shengkaian uses advanced polymer materials as the humidity-sensitive conversion element. Through its unique water absorption and desorption process, it achieves dynamic equilibrium monitoring of moisture in oil. This oil moisture sensor utilizes the influence of moisture on the dielectric constant of polymer materials to precisely capture changes in capacitance, thereby outputting the corresponding humidity variation and providing a reliable basis for real-time monitoring of moisture content in oil.
The SKAA2 oil micro-water sensor uses polymer material as the humidity-sensitive conversion element, achieving dynamic moisture equilibrium through water absorption and desorption processes. The dielectric constant of water is much larger than that of pure polymer materials, and the dielectric constant of the polymer material after water absorption changes significantly due to the variation in adsorbed moisture, thereby causing changes in capacitance value. The oil micro-water sensor outputs the corresponding humidity variation.
