Lightweight Seismometers

The three-axis miniature broadband seismograph is a lightweight, low-power, high-performance three-axis integrated broadband seismograph newly developed and manufactured by Beijing Gangzhen Technology Co., Ltd. It consists of three identical inclined pendulums evenly distributed along the circumference, and incorporates a force balance electronic feedback circuit, coordinate transformation circuit, and control circuit.

The instrument features:

1. Operating environment: temperature range -35~55℃, relative humidity 0-98%;

2. Low power consumption: operating power consumption less than 0.7W;

3. High performance: self-noise 0.025Hz~10Hz, lower than NLNM;

4. Easy installation: orientation accuracy is ensured by dual orientation pointers, automatic pendulum opening and zeroing upon power-on, and automatic pendulum locking upon power-off. It has an automatic zero-position monitoring function, automatically zeroing when the pendulum position deviates significantly during long-term observation to ensure normal operation.

1.Wide Range, Accurate Operation
Because the system utilizes innovative force balance technology, it is capable of sensing from 0.0083 Hz to 80Hz. The detector system provides very sensitive and accurate readings with very low self-noise which is below the NLNM threshold. This allows for the acquisition of very accurate seismic signals.

2. Small Size and Weight with a Single Housing
This product utilizes single-housing design that incorporates three-axis (UVW) detection; its weight of 5.5kgs results in lightweight transportation and rapid deployment.

3. Low-power Consumption
The design of the system is for low-power application, the system can operate with limited power source, with average power consumption of 0.7W to 0.7W which are ideal for unattended field monitoring for extended periods of time.

4. Smart Automatic Operations
You get the ability for the automatic feature to unlock when powered on and locked when powered off, which includes auto zero correction for continuous stable operation over a long period of time, with very little manual interaction.

5.Easy Installation and Fast Deployment
Dual direction setters allow for very accurate orienting and allows for very fast installation, which will reduce the amount of time you are out in the field installing.

6.Rugged and Reliable
The device has been designed for harsh conditions and is rated to IP67 and will operate between -35°C and +55°C, making it suitable for such demanding outdoor usage situations.

7. High Dynamic Range
Dynamic range that is greater than 155 dB provides the ability to accurately detect small microseismic events and also measure large seismic events.

8. A Wide Range of Uses
They are perfect for national seismic networks, monitoring earthquakes, and oil and gas exploration. The systems work well for earthquake-like events caused by mining operations, as well as for scientific study.

The National Seismic Network, its stations, and regional seismic networks are used in research fields such as natural earthquake observation, reservoir-induced earthquake monitoring, mine earthquake monitoring, and broadband seismic observation and underground structure imaging for oil and gas exploration. They can be used for scientific investigations such as long-term fixed observation and mobile seismic observation.
