Pressure sensors and core modules are critical components in modern industrial automation, the Internet of Things (IoT), and consumer electronics. The core sensing element acts as the “heart” of the sensor, determining overall system precision, stability, and longevity.
Working Principle of Pressure Sensor Core Modules Pressure cores typically operate on piezoresistive or piezoelectric principles. When external pressure is applied to the sensitive diaphragm, the strain resistors inside the core deform, changing the resistance value and converting it into a standard electrical output signal. The introduction of Micro-Electro-Mechanical Systems (MEMS) technology has driven core modules toward miniaturization, high integration, and enhanced sensitivity.
