1.The introduction of instrument
G018914 acceleration sensor 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 G018914 accelerometer is a fully sealed, waterproof and small volume vibration sensor for low frequency vibration measurement. The principle of differential magnetic steel induced vibration is adopted and the passive closed-loop servo technology is used to obtain good low frequency characteristics and good impedance matching characteristics. Vibration acceleration and acceleration parameters can be output. The sensor can be used with the G01NET series acquisition instrument produced by our company.
