Automotive Sensor - oil pressure sensor means set miniature sensors, actuators and signal processing and control circuitry, interface circuits, communication and power in one of the micro-electro-mechanical systems. Commonly used silicon piezoresistive silicon capacitive, both produced on silicon micro-mechanical and electronic sensors. General situation, we adopted the oil pressure sensor to detect oil inward car how much oil and converts the detected signal into signals of automotive sensor type, we can understand, to remind us how much oil, or you can also go How far, and even remind the car need to add oil. Working mechanism of rotary sensor soft iron magnetic sensors, coils and permanent magnets stationary. Measuring gear made of magnetically permeable material mounted on the rotating member under test, each turned a tooth, measured changes in magnetic resistance formed between the gear and the first soft iron automotive sensor supplier, the magnetic flux is also changed once. Electromotive force induced in the coil changes in frequency (pulses) equal to the measured speed of the gear teeth and on the product. Hall Hall effect sensors ⒈ semiconductor or metal foil is placed in a magnetic field of automotive sensor manufacturers, when a current (magnetic field perpendicular to the sheet plane direction) flows, electromotive force is generated in a direction perpendicular to the magnetic field and electric current, which a phenomenon known as the Hall effect. ⒉ Hall element germanium material commonly Hall (Ge), silicon (Si), indium antimonide (InSb), indium arsenide (InAs) and so on. N-type germanium easy manufacturing, Hall coefficient, temperature performance, good linearity; linearity of the P-type silicon preferably, Hall coefficient, temperature performance with an N-type germanium, but low electron mobility, with a load capacity than poor, usually do not make a single Hall element.
