Wuhan Zhongdi Hengda - Collapse Meter
(1) Product Introduction
The ZDHD-ZWBT tilt-acceleration sensor is a triaxial tilt and vibration monitoring sensor that integrates data acquisition, wireless communication, power supply, and self-protection. Its main function is to real-timely measure changes in tilt and vibration.
(2) Working Principle
It integrates a triaxial MEMS acceleration sensor, a magnetic declination sensor, and a positioning module to monitor acceleration and angle changes in real time. It can perceive overall attitude changes through angle or acceleration variations.
(3) Product Features
① The housing is made of high-strength, anti-aging materials, enabling long-term field use for uninterrupted measurements;
② Operating temperature range: -40℃ to +85℃, with temperature compensation;
③ Lightning and static electricity protection performance (±60kV/600W);
④ Adopts an integrated structural design with a fully sealed structure, achieving an overall protection level of IP68, suitable for harsh natural field environments;
⑤ Collects multiple monitoring parameters, including triaxial tilt, tilt angle, azimuth, vibration frequency, amplitude, battery voltage, ambient temperature, and GPS+Beidou dual-mode positioning information simultaneously, which greatly enhances the correlation of collected data and facilitates subsequent data analysis;
⑥ Supports trigger-based acquisition: when the sensor tilts or vibrates, it can immediately collect data and send an alert, making it applicable for studying motion patterns, monitoring and early warning, and on-site anti-theft.
