Product Description

The GZP6185(AJ series) is a pressure sensor product developed by Sencoch for the automotive applications. The product packaging adopt ceramic diaphragm core. The measured pressure work on the ceramic diaphragm and then generate a voltage signal, where the signal is processed by an automotive-grade signal conditioning chip(ASIC). The ASIC performs calibration and compensation for raw signal and convert pressure signals into standard analog output signals (range and output is customizable). The GZP6185 pressure transducer has the advantages of fast response, high reliability and good stability, and is a high cost-effective sensor product.

Function Description

The working principle of GZP6185A is based on the piezoresistive effect of ceramics. The measured medium acts on the ceramic diaphragm through the pressure interface (such as a threaded connection), causing it to deform. The Wheatstone bridge on the back of the diaphragm converts the deformation into a weak differential voltage signal. The built-in dedicated signal conditioning circuit (ASIC) then amplifies, temperature-compensates, linearizes, and zero-adjusts this signal, ultimately outputting a high-precision, high-stability standard analog signal (e.g., 0-5V or 4-20mA). Throughout this process, the robust and corrosion-resistant ceramic diaphragm serves the dual roles of pressure sensing and medium isolation, making it particularly suitable for measuring corrosive, high-viscosity, or contaminated media.
