1.The introduction of instrument
QZ2013 force balance 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 uses active closed-loop servo and force balance technology, has good low-frequency characteristics and good impedance matching characteristics.
QZ2013force balance acceleration sensor can be used with G01NET series collector produced by our company, or with other collectors that collect voltage signals.
