Hello Salih,
Thank you for your interest in NXP’s TPMS solutions.
At this time, we do not offer TPMS sensors that support pressure ranges beyond 1518 kPa (220 psi). The NTM88K series is our highest-range TPMS solution, with an operating pressure range up to 1518 kPa.
For applications requiring higher pressure monitoring (such as 300 to 350 psi), you may need to explore specialized or industrial-grade TPMS solutions from other vendors.
BRs, Tomas
