Telecom tower monitoring system

Descriptions

SSM7001A tower motion sensor adapts MEMS accelerometers and gyroscopes with advanced strap-down technology and FFT technology, to on-line monitoring the telecom tower moving status with any harsh working condition. This sensor output:

n  Six monitoring data: tower azimuth angle, tilt direction, tilt angle, horizontal deviation displacement(refer to tower vertical position), shaking amplitude and frequency

n  Four settable warning thresholds:horizontal deviation displacement, tilt angle, shaking amplitude, shaking frequency.
