Geobit Instruments products

GEOtiny30/60/120 is a compact miniature digital broad-band seismometer which integrates three seismic and three acceleration channels. It supports high resolution 24bit digitizer, embedded linux OS and GPS or NTP timing. Seedlink server ensures reliable real time data telemetry while large storage volume ensures long period local data recording. The instrument has very low power consumption so it can operate getting powered from a small 12Vdc battery. Due to its small size provides the ability to be buried underground.

The GEO-S120 broadband seismometer is a product rely on years of experience in designing high precision, low noise, and reliable seismic equipment. Based on a very sensitive capacitive transducer that monitors the position of the seismic bass and a feedback loop that generates signal output proportional to velocity with extended bandwidth 120sec to 80Hz. The instrument has low self-noise so it is ideal for local, regional and teleseismic earthquake recording. No mass lock is required and supports automatic mass centering. The sensor provides calibration input and communication via serial port. The GEO-s120 design is exceptionally versatile, ideal for both direct bury and vault use cases. The seismometer casing is made from hard anodized aluminum or stainless steel.

GEObit introduces GEOsix series high resolution 6+1 analog seismic channels telemetry digitizer/recorder. The size of the instrument is only 168 x 106 x 68mm. The power consumption is only 1.2W for 6 channels. The available sampling rate is 100 to 500sps/6ch, 100 to 1000sps/3ch and optional lower sampling intervals are supported. Built-in GPS receiver combined with ultra-accurate DPLL unit providing time drift 10e-9 sec ensures timing stability even in the absence of GPS signal. NTP timing is also available. The unit is very flexible and accepts several types of analog front end units so any type of seismic sensor can be connected. Additionally, it provides eight extra-low resolution and rate analog inputs for seismometer mass position monitoring, or any other environmental parameter monitoring.

GEObit introduces GEOthree series high resolution 3+1 analog seismic channels telemetry digitizer/recorder. The size of the instrument is only 168 X 106 X 68mm. The power consumption is only 0.9W for 3 channels. Available sampling rate is 100 to 1000sps and optional lower sampling rates are supported. Built-in GPS receiver combined with ultra-accurate DPLL unit providing time drift 10e-9 sec ensures timing stability even in the absence of GPS signal. NTP timing is also available.

GEO3tiny is a compact miniature seismic digitizer which integrates three seismic and three acceleration channels plus three extra analog channels for seismometer mass monitoring. It supports high resolution 24bit digitizer, embedded linux OS and GPS or NTP timing. Seedlink and Earthworm server ensures reliable real time data telemetry while large storage volume ensures long period local data recording. The instrument has extremely low power consumption so it can operate getting powered from a small 12Vdc battery.

GEOtiny10 is a compact miniature digital seismometer which integrates three seismic and three acceleration channels. It supports high resolution 24bit digitizer, embedded linux OS and GPS or NTP timing. Seedlink server ensures reliable real time data telemetry while large storage volume ensures long period local data recording. The instrument has very low power consumption so it can operate getting powered from a small 12V DC battery. Due to its small size provides the ability to be buried underground. Modular sensor interface allows the user to select between a variety of sensor types and frequency corners (10sec, 5sec, 2sec, 1sec, 2Hz, 4,5Hz), thus covering the short period and wide band seismic range. Design simplicity is the great advantage and it is reflected to the price which is only fraction of the common commercial seismometers. The user is able to deploy even 100% more units than using common seismometers at same cost.

The S-100 MK3 (third generation) is a three-component velocity output seismic sensor. The design is based on the force-balance principle, thus using three simple geophone elements, the frequency bandwidth is extended from 90Hz, down to 0.1Hz. The default cable length between the sensor casing and the electronics box is approximately 20 meters but it can be extended up to150 meters.

The S-100 is a three-component velocity equivalent output seismic sensor. The unit is ideal for local and regional seismicity and microseismicity monitoring as well as, for induced micro-seismicity monitoring.

The C-100 is a three-component velocity equivalent output seismometer. The sensor consisted basically from three geophone elements, one per axis. When combined with our force-balance electronics (third generation), the bandwidth is extended to 10sec – 98Hz, and the sensitivity is increased to 1500V/m/sec.

This type of sensor has been designed for microseismic events recording during hydraulic fracturing reservoir experiments. The sensor body has been designed in order to house double geophone strings at each axis. The orientation follows the 3-axis principle. This sensor has an external diameter of 50mm allowing it to be installed into small and shallow boreholes, hence reducing the cost of installation. Using single geophone element per axis, the electronic noise floor becomes a limiting factor for this type of acquisition. Increasing the gain and minimizing the noise floor of the sensor give us the ability to record even smaller events.
