TMS® Sensor – Internal

TMS® sensors measure pressure and temperature and estimate their own battery condition. Every sensor has a unique four-digit identity code (ID) printed on the product label. Periodically and on certain conditions, each sensor broadcasts its ID and measurements as a radio transmission.

Fitting sensors:

Our sensor allows easy assembly using the unique TMS® rubber toggle system. It is attached to an industry standard tire patch that is stitched to the sidewall. The patches are flexible and lightweight. Patching to the sidewall keeps the sensors away from the rim and the tread.
