SP12T

PRODUCT BRIEF T Y RE PRE SSU RE SE NSOR FOR HEAVY VEHICLES SP12T is a piezoresistive pressure sensor designed for tyre pressure measurement in heavy vehicle applications. The design is based on proven high-volume, low cost production processes developed for products to be used in automotive applications. 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 SP12T measures pressure, temperature and supply voltage, 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.
