Perfect for Ensuring the Integrity of Structures, Sensitive Equipment, and Human Comfort
Soft dB's SGS, Smart Geophone Sensor, is ideal for detecting microearthquakes and measuring vibrations caused by explosives, blasting, hydraulic hammers, etc., often used on construction and mining sites.
Its exceptional signal quality enables detection of vibrations as low as one micrometer per second, with no risk of high-frequency saturation.
This triaxial geophone is perfect for monitoring vibrations near sources of impact, such as a jackhammer close to a wall.
The SGS superior capabilities ensure the integrity of structures, buildings, and infrastructures adjacent to the worksite, protects vibration-sensitive equipment, and maintains the comfort of residents in neighbouring communities of the site.
Simplified Maintenance and Installation
Save time and money.
Our signal acquisition and processing system is integrated directly into the geophone. Therefore, you will only need to send the geophone to the laboratory when calibration and certification is required.
This allows you to avoid having to ship the complete monitoring station (incurring unnecessary costs), as well as having to compensate additional stations in the field, as to not disrupt continuous monitoring.
Our triaxial geophones are also interchangeable with all Soft dB monitoring stations, so you can simply use another geophone in the field during calibration.
What's more, no reconfiguration is required when your vibration sensor returns to the field after annual maintenance, considerably reducing your risk of error. Everything is entirely automated, ensuring continuity in the quality of measured information.
One of the Most Powerful, Customizable, Alert and Reporting Systems Available on the Market
Be informed only when relevant to you.
Our alarm system is flexible in capturing threshold exceedances and can be adjusted based on your specific project criteria.
For example, alarms can be programmed for both peak and RMS speeds, and even for accelerations, as required.
This allows you to be informed only when an action is required on your part.
Automatic Sensor Check
No more questions about data quality. Get consistently reliable measurements.
Every day, each sensor performs an automatic check to ensuring optimal functionality and validity of the data being supplied.
Not only are these results recorded, they can be accessed at any time via our Soft dB Web monitoring platform.
Should a sensor detect a deviation in functionality, an automated alert is sent to you.
Valid, High-Quality, and Interference-Free Data
The vibration data that you receive is exactly what has been measured. No contamination.
Our triaxial geophones incorporate intelligent technology that processes the signal directly within the sensor, considerably reducing the risk of interference, thereby ensuring valid, accurate, and reliable data.
SGS triaxial geophones allow you to measure vibration data with cables of up to 100 meters, with no loss of signal, giving you the flexibility to find the best location for communication and measurement of your most critical points.

Why Choose a Smart Vibration Sensor That Is Independent of a Station?
To meet certain certifications and compliance requirements, the vibration sensor and its data processing system, which converts signals into digital data, must be regularly calibrated together.
This means that if your signal processing system is integrated into a monitoring station, you will need to send not only the vibration sensor but also the associated monitoring station, known as "paired" with that sensor, to the laboratory. Each year, you will need to:
- Disconnect each station from the network to install a new one while the old one is being calibrated.
- Purchase additional stations to compensate for those being calibrated.
- Buy vibration sensors to replace those being calibrated.
- Reconfigure your system since each sensor is designed to work with a specific station to which it is paired, significantly increasing the risk of errors in the continuity of the measured data.
This process quickly becomes complex and very time-consuming, especially when managing a large fleet of monitoring stations.
|
That’s why our R&D team has developed smart vibration sensors specifically designed to meet the practical realities of the field and provide the best tools for professionals. |
With our signal processing system integrated into the SGS triaxial geophone, there’s no need to send the station for calibration. Only the vibration sensor is required. During its calibration, you can compensate with another smart geophone that can connect to any Soft dB monitoring station, just like that.
You reduce your costs by avoiding the purchase of additional stations to cover those in calibration, and you save significantly on time. There’s no need to reprogram the station after the sensor's calibration.
Your annual calibration becomes much simpler, quicker, and more efficient.
How Does a Triaxial Geophone Like Soft dB’s SGS Work?
A triaxial geophone is equipped with three sensors, each oriented along the X, Y, Z axes for complete and precise measurement of ground vibrations. It is ideal for measuring very high vibration velocities, often generated by impact equipment used on construction sites, such as hydraulic hammers.
Here are the operating steps for the SGS triaxial geophone:
1. When vibration waves generated by rapid impacts pass through the ground, the triaxial geophone detects movements in each direction (X, Y, Z).
2. Once captured, these vibration waves are processed directly inside the sensor and converted into a digital signal. Unlike analog signals, the digital signal is not subject to electrical voltage variations caused by magnetic fields along a cable, for example, ensuring high-quality, accurate and reliable data, free from interference.
3. The digital signal then travels in a cable up to 100 meters long, with no risk of data contamination, giving you the flexibility to have a wider range of measuring critical points.
4. The digital signal is routed from the cable to our seismographs, also known as Soft dB monitoring stations. It is then sent it to our secure Cloud server, which communicates directly with our Monitoring Web platform.
5. Via the Monitoring Web platform, you can view all your vibration and acoustic data, in real-time, set alarms, receive automated reports, and much more.
It should be noted that triaxial geophones are rarely able to measure the strong ground motion often associated with major seismic events, such as earthquakes. The risk of triaxial geophone saturation is high. For these situations, other smart vibration sensors, such as Soft dB's SVS, is an essential option to consider.
Geophones and Mems Are Available from Soft dB
For many projects, it's common to require the use of both MEMS (to measure high seismicity) and geophones (to detect microseismicity). However, they are often provided by different suppliers. This typically involves managing different web platforms to monitor your vibration data, receiving reports from different suppliers, paying multiple subscription fees... Complicated!
At Soft dB, we believe in simplicity, which is why we offer both.
Our R&D team works closely with our field experts to design and manufacture some of the industry's most advanced intelligent vibration sensors, such as SGS ultra-precise geophones and SVS MEMS sensors.
