High sensitivity accelerometer (IEPE) LZDY1-G

This series of acceleration sensors has voltage output, high sensitivity, and low bottom noise, and is suitable for low-frequency vibration testing applications such as building vibration monitoring, earthquake detection, bridge structure testing, ground and foundation vibration monitoring, etc.

Model: LZDY1-G

1） Overview:
The high-sensitivity single axis voltage type (IEPE) LZDY1-G is a miniature voltage type accelerometer independently developed by our company. All its indicators meet the requirements proposed in ISO2954-1975 and GB13824-1992. This series of acceleration sensors adopts the principle of piezoelectric effect, processed by internal amplification circuit, and powered by 2-10mA constant current source. Compared with charge amplifiers, except for the low operating temperature range, they have better anti-interference and signal distortion than charge output sensors. It has a wide frequency response, good dynamic characteristics, and strong anti-interference ability.
Application scope:
● Building vibration monitoring
● Bridge structure testing
Ground vibration monitoring
Geological structure research
● Foundation vibration monitoring
Monitoring of dam structure
Structural monitoring of sports venues
● Earthquake warning
feature:
Low frequency and low vibration level measurement
Low price, high sensitivity
Passive, positive piezoelectric effect
