Product Manual
BST1712-XT - Tire pressure measure transmitter - Standard version
Product description
BST1712-XT is an extensor that, assembled on a standard tire valve, measures the air pressure of the tire,
temperature and battery voltage level and transmits these data through radio interface (434MHz license-free
ISM band), with proprietary Micro.sp© technology based on short pulses transmitted with Pulse Position
Modulation (PPM), which guarantees high RF peak power, as required for radio link reliability, but with a very
low average power and consequently low current consumption.
Powered by a standard CR1225 lithium battery, it can guarantee a lifetime of at least 3 years.
