1.The introduction of intrument
QZDB-A dynamic strain gauge is a high-quality sensor with independent intellectual property rights jointly developed by Engineering Mechanics Institute of China Seismological Bureau,and Hebei Zhenchuang Electronic Technology Co., LTD.
The strain gauge selects high-precision imported resistance strain gauge as the sensitive element, and is manufactured by the paste group bridge and modification process. At the same time integrated signal conditioning circuit, direct output voltage signal, no need to connect strain gauge.
The QZDB-A dynamic strain gauge 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.
