1.The introduction of instrument
QZ2013-Y piezoelectric acceleration sensor is a high-quality sensor with independent intellectual property rights jointly developed by the Institute of Engineering Mechanics, China Earthquake Administration, and Hebei Zhenchuang Electronic Technology Co., Ltd.
The sensor is designed with high-precision piezoelectric materials and has good low-frequency characteristics and a large effective bandwidth. The QZ2013-Y piezoelectric acceleration sensor can be used in conjunction with the G01NET series collector produced by our company, and can also be used in conjunction with other collectors that collect voltage signals.
