Tire pressure sensor Masuma, TP-138

Specifications:

Masuma tire pressure sensors are engineered to meet OEM standards and support the most common operating frequencies: 433MHz and 315MHz.

The product line includes sensors compatible with three types of second-generation direct TPMS (TPMS II):

1. Classic system with a single antenna
   A central receiving antenna captures signals from individual sensors, each with a unique identifier. Diagnostic tools are required to register new sensors.
2. System with an antenna and wheel-mounted triggers
   In addition to a central antenna, each wheel arch is equipped with a trigger (reader) that detects signals from the corresponding sensor. This enables automatic registration of new sensors during the first drive.
3. System with an antenna and dual-axis acceleration sensors in the TPMS units
   Based on acceleration data and signal strength, the system identifies each sensor. New sensors are automatically registered during the first drive without the need for wheel-mounted triggers.

Key advantages of Masuma TPMS sensors:

• High measurement accuracy — precise and consistent pressure readings in real time.
• Reliable performance — stable operation under various road and climate conditions.
• Seamless integration — full compatibility with OEM TPMS in modern vehicles.
• Automatic pairing — hassle-free installation and replacement (in supported systems).

Battery life:

• Up to 8 years in storage.
• Up to 4 years under regular vehicle operation.
