Product scope of application
The thick film ceramic sensor for oil detection filter adopts screen printing technology to directly print the slurry on the alumina ceramic substrate, and is made by high-temperature sintering. Changes in oil pressure or viscosity cause deformation of the ceramic diaphragm, which outputs a linear electrical signal through a Wheatstone bridge. Ceramic substrates and thick film resistor layers can resist chemical corrosion in engine oil and fuel, making them suitable for harsh environments. The temperature stability of the thick film ceramic sensor for oil detection can adapt to high temperature scenarios such as engine compartments. Its high precision and stability, anti overload design can prevent the diaphragm from breaking due to pressure overload, and built-in compensation circuit, amplification circuit, and alarm function in the signal processing integration.

Application Cases
The thick film ceramic sensor for oil detection filter is applied in oil pressure monitoring, installed in the main oil passage of the engine, to detect the oil pressure in real time, prevent wear caused by insufficient lubrication, and trigger the alarm circuit to light up the warning light when the pressure is abnormal. In the application of oil pollution detection, by analyzing the particle content or viscosity changes in the oil, the viscosity and pollution degree of hydraulic oil and gear oil are detected in real time, and the pollution or deterioration of the lubrication system is warned. This is commonly used in automotive engine control systems. In fuel system monitoring, it is used to detect the fuel level or pressure in the fuel tank, and its corrosion resistance is adapted to the fuel medium, integrated into the automotive electronic instrument panel.
Frequently Asked Questions
What are the main advantages of using a thick film ceramic sensor for oil detection?
The sensor offers high sensitivity, excellent corrosion resistance, and high-frequency stability. Its alumina ceramic substrate ensures durability and long service life under harsh conditions like high temperatures and chemical exposure.
What is the operating temperature range of this sensor?
The sensor operates effectively within a temperature range of -40 ℃ to 150 ℃, making it highly suitable for extreme environments such as automotive engine compartments.
Can the sensor parameters be customized for specific applications?
Yes, we provide comprehensive customized services. We can adjust dimensions, materials (such as Al2O3 or AlN), and electrical parameters to fit your specific system requirements.
