High sensitivity accelerometer (PE) LZDH1-G

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

Model: LZDH1-G

1） Overview:
LZDH1-G high-sensitivity single axis acceleration charge type (PE) is a high-sensitivity charge type acceleration sensor 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, using piezoelectric ceramics or quartz as sensitive elements, with wide frequency response and good dynamic characteristics
Application scope:
● Building vibration monitoring
● Bridge structure testing
Ground vibration monitoring
Geological structure research
