Passive Seismic Survey Acceleration Device 3c Sensor Microtremor Survey Seismograph Vibration Monitoring Accelerometers

1.Application
1)Micro-tremor measurement and vibration monitoring of ground and various structures.
2)Micro-tremor measurement of general engineering structures such as bridges, buildings, docks, dams, marine platforms, etc. and vibration measurement and monitoring in various vibration tests.
3) Vibration measurement of large rotating equipment such as hydro generator sets.
4) Weak vibration measurement of vibration isolation platforms, etc.
5) Ultra-low frequency large-amplitude measurements of highly flexible structures such as suspension bridges.
6)Other low frequency ultra-low frequency vibration measurements.

2. Features
1) Multifunctional: With the micro toggle switch of the pickup, acceleration or velocity can be measured directly, and when mated with the amplifier, displacement can be measured.
2) Easy to use: The pickup does not require power supply and zeroing.
3)Excellent performance: Due to the use of passive servo feedback technology, low frequency (down to 0.5 Hz) and large displacement (100mm) vibration measurements can be achieved.
4) Wide frequency band, high resolution, large dynamic range, good shock resistance, suitable for transportation, and can be directly mated with various data acquisition systems.
