Introducing the PSD0401120: PUI’s Latest Digital MEMS Pressure Sensor

Overview

PUI Audio is proud to present the PSD0401120, our newest MEMS pressure sensor designed for applications demanding precision and reliability. Featuring a compact 10-pin LGA surface-mount package, this piezoresistive pressure sensor offers high sensitivity and low power consumption. It is well-suited for diverse applications, including industrial automation, medical devices, and more.

The Technology Behind PSD0401120

The PSD0401120 utilizes MEMS (Micro-Electro-Mechanical Systems) technology, featuring a piezoresistive pressure-sensitive network. It’s built around an elastic film and four resistors forming a Wheatstone bridge structure. This design enables the sensor to detect pressure changes by measuring the deformation in the resistors, converting these changes into a voltage output that is directly proportional to the applied pressure.

This sensor covers a wide measurement range of 30kPa to 120kPa and delivers high-resolution data through its 24-bit delta-sigma analog-to-digital converter (ΔΣADC). The PSD0401120 also integrates a temperature sensor, ensuring precise readings with a resolution of 0.1°C.
