An inflation pump sensor is a device used to monitor critical parameters such as pressure, flow, and temperature in real time. Once these data are quickly transmitted to the control system, it can adjust the inflation rate and duration accordingly to ensure each inflation process strictly adheres to preset standards.
Pressure sensor resolution refers to the smallest pressure difference that a sensor can detect and measure accurately. It represents the level of detail or granularity in pressure measurements that the sensor can provide. In essence, resolution defines the smallest increment or step size that the pressure sensor can distinguish between two pressure levels
Absolute pressure sensors can accurately measure pressure changes on the seat surface, monitor the user’s weight distribution and sitting posture in real time, and automatically adjust the seat to provide ergonomic support. They can also identify the passenger seat status in the car seat, assist in adjusting the safety system (such as the deployment of airbags), and increase passenger safety.
The tire pressure monitoring system (TPMS) uses pressure sensors to monitor tire pressure in real time to ensure driving safety. Internal and external sensors provide accurate data, and the ABS wheel speed sensor indirectly detects pressure changes through speed differences.
La pression absolue se réfère à la pression mesurée par rapport à la pression nulle absolue – Un vide parfait où il n'y a aucune molécule pour exercer une pression. Ce concept est fondamental pour comprendre toutes les mesures de pression car elle fournit un point de référence immuable.
Micro pressure sensors are small yet highly sensitive devices that measure pressure changes in various environments. In today’s high-tech industries, these sensors have become essential in applications ranging from medical devices to aerospace systems.
