Rotational Seismometers

​Based on Fiber-Optic-Technology blueSeis-3A is today the best and most reliable rotational seismometer: 3-axis, low-noise, broadband, high dynamic range and flat passband solution with “geosciences-ready” interfaces including heading and time stamping.

Main features and benefits:

• 3 Interferometric Fiber Optic Gyroscopes (I-FOG) for low self-noise and broadband measurement
• DC signal for absolute rotation measurement
• High dynamic range
• Ethernet output of time stamped data
• Field-proven technology
• Flat frequency response
• Rotation as a new observable in seismology
• Easy to deploy: no calibration, no tilt range limitation, insensitive to environmental conditions
• Heading provided by the system
• 2-in-1: «weak motion» low-noise + «strong motion» dynamic
• Plug and play interfaces

iX-1B is a high-grade one-component gyroscope with low-noise, great stability, and wide dynamic range, featuring absolute digital rotation rate in mard/s.

A specific benefit of this product is its compactness which allows the integration of the sensor in complex systems. iX-1B is a highly versatile sensor thanks to limited power consumption, simple configuration of the factory-calibrated digital output, which make it the perfect ally to develop innovative solution in a large number of application: calibration, dynamic motion feedback, close-loop operation actuation etc…

Main features and benefits

• Interferometric Fiber Optic Gyroscope
• Absolute measurement of rotation rate
• High dynamic range
• Digital output factory-calibrated (no-need for user calibration)
• Flat frequency response on very broadband 1000 s – 200 Hz
• Low power consumption
• Compact (compared to performance)

blueSeis-1C is a portable one component very-low-noise broadband rotational sensor, featuring absolute digital rotation rate in nard/s.

A specific benefit of this product is to have a sensor part without power consumption probed by a remote and compact electronic. It allows the integration of the sensor in complex systems with a limited risk of perturbation while ensuring easy access to electronic part.

BlueSeis-1C is a highly versatile sensor thanks to limited power consumption (3 W), circular shape of the sensor with empty space at its center, simple configuration of the factory-calibrated digital output, which makes it the perfect ally to develop innovative measurement system in many applications: Ocean-Bottom system, scientific instrument stabilization, Seismic station upgrade etc…

Main features and benefits:

• Interferometric Fiber-Optic Gyroscope
• Absolute measurement of rotation rate
• High dynamic range
• Digital output factory-calibrated (no-need for user calibration)
• Flat frequency response on very broadband 1000 s – 50 Hz
• Cold and static sensor part with remote electronic
• Low power consumption
• User-friendly web-MMI
• Compact (compared to performance)
• Optimized sensor shape to save volume of the center of the coil

The blueSeis’ team conducts many evaluation missions, over the world in collaboration with partners, to demonstrate the blueSeis’s measurement capabilities on seismology and volcanology, ground tomography, infrastructure monitoring and so on.

From 6C stations to large arrays, modern seismic analysis are more demanding on orientation accuracy and must rely on a high-quality system that gives the absolute reference for true North alignment. With Seistans, iXblue offers a fully strapdown gyrocompass that provides very accurate heading and attitude.

With its light weight and small size, it is the optimal solution for seismic sensors alignment that guarantees high precision and reliability for seismologists’ measurements. Dedicated to instrument orientation measurement on the field and operating even if GNSS is denied, Seistans comes with a full option suite to fit any specific case to transfer the North line to your instrument.

Benefits:

• Free of export
• GNSS denied environment compatible
• Fast settling time
• Maintenance and calibration free
• 5-year warranty
