The AMT/YP-SHY three in one sensor for oil products adopts piezoelectric resonant MEMS components. Through an internally integrated high-precision signal sampling and processing unit, combined with advanced algorithms, it can automatically detect the temperature, dynamic viscosity, and density of liquids in real time. It is applied to hydraulic systems, gearboxes, diesel units, turbine units, air compressors and other equipment, suitable for various oil products such as hydraulic oil, gear oil, transformer oil, turbine oil, diesel engine oil, aviation fuel, kerosene, gasoline, etc.
