NPX1 Tire Pressure Sensor

Amphenol Advanced Sensors logo

NPX1 Tire Pressure Sensor


NPX1 integrates a silicon pressure sensor, an 8-bit RISC processor, and a LF-input stage to meet market demands for flexible, customer specific behavior/solutions and overall system cost reduction for the Remote Tire Pressure Monitoring (RTPM) customer. The programmable version of this sensor is available for development purposes, allowing the customer to download the application code in an electrically programmable EEPROM version.

 
This tire pressure sensor is intended for developing the application specific program. In order to ensure high reliability, the NPX1 sensor has the measurement routines (pressure, temperature, and supply voltage) implemented in ROM.
