QTB351 metal base pressure sensitive chip

The QTB3 51 type metal-based pressure-sensitive chip uses MEMS technology to directly fabricate the strain resistance on a 17-4PH stainless steel substrate. Through the elastic deformation of the substrate, the chip outputs an mV voltage signal linearly related to the measured pressure to achieve Accurate and fast measurement of the measured pressure. Designed for the high specification requirements of sensor performance, reliability and stability of major sensor OEMs and integrators, the chip outputs mV voltage signals, and customers can process the signals according to their actual requirements.
