Product Description

The GZP191 piezoresistive pressure sensor chip is designed for applications in biomedical engineering, industrial control, IoT, and other fields. Its core component is a silicon piezoresistive pressure sensing chip fabricated using MEMS technology. The chip is laser trimmed for precise span and offset calibration and temperature compensation and provide a highly accurate and linear voltage output directly proportional to the applied pressure.

The GZP191 pressure sensor chip features a standard through-hole package for easy installation. The barbed inlet nozzle design enhances the retention of the intake hose.

Note: The GZP191 pressure sensor chip is compatible only with non-corrosive media such as air.

Function Description

This product is made with advanced micro-electromechanical principles. Its key component is a silicon piezoresistive pressure sensor manufactured using MEMS technology . This pressure sensor consists of an elastic membrane and four resistors integrated into the membrane. These four piezoresistors form a Wheatstone bridge structure. When pressure acts on the membrane, the bridge generates a voltage output signal that is linearly proportional to the applied pressure. The user can amplify, compensate for temperature and linearize this signal to obtain an output voltage that is in a prescribed relationship with the applied pressure.
