TYRE PRESSURE SENSOR WITH ACCELEROMETER

S P 1 2 is a piezoresistive pressure sensor and accelerometer designed for tyre pressure measurement applications.The design is based on proven high-volume, low cost production processes developed for products to be used in automotive applications.The SP12 is supplied in a 14 pin SOP (Small Outline Package) plastic package.

The sensor design is based upon SensoNor’s proprietary and patented solutions aimed at high reliabilty measurements in harsh environments, still with a predictable and stable quality in high volume applications.

The SP12 measures pressure, temperature, supply voltage and radial acceleration, and by integrating these functions with an ASIC in one package, SensoNor has developed the ideal product for tyre pressure monitoring applications, offering the system designer the flexibility to determine sequences and functionality according to his customers demands.
