Systems

International Earth Sciences (IESE) manufactures, retails, and installs a wide range of Monitoring instruments/systems for Geotechnical, Geothermal, Seismic, Mine Seismology and Telemetry systems.

 

IESE – Telemetry System

Enclosure Sky Tower small

The remotely stationed IESE Telemetry system is designed to automatically acquire data from a wide range of Geotechnical, Geothermal, Seismic and Mine Seismic sensors/instruments that are installed on site. The measured data is sent to the client’s/IESE database using varies types of communication technology; 3G/4G GSM network, IP networks, Ethernet-over-Radio and Ethernet-over-satellite. IESE offers custom design, manufacturing and installation to suit your specifications.

 

IESE – MANUFACTURING

Downhole instrumentation for use in micro-earthquake detection. Our Seismometers (Sondes) feature passive sensors with high sensitivity, reliability and longevity, for permanent or temporary installation in hostile borehole environments. We offer to work with clients to develop custom-designed models to satisfy specifications and conditions.

Hydraulic Holelock for Seismometer Coupling

Hole_lockHolelock devices are used to couple sensors at specific depths in boreholes for either short or longer term measurements (<2 years). The simple hydraulic components provide reliability and high coupling force.

High-Pressure and Temperature Borehole Seismometer

s31f-15 The F41-15 is a high-tilt and high temperature triaxial borehole seismometer. It is designed for installation in extreme high-temperature environment up to 150 °C, such as geothermal systems.This model is suitable for test well or behind casing installation.

Shallow Posthole Seismometer

s31f-2.0The F72-2.0 is IESE’s readily deployed shallow posthole sonde for use in micro-earthquake detection and analysis. It is designed for installation in up to 100 m vertical holes. An alternate model, the F72-4.5 offers a higher tilt tolerance in exchange for a higher corner frequency.

Slimhole Seismometer

S51f-4.5 The Model F50-4.5 is a moderate-tilt and moderate-temperature triaxial borehole seismometer. It is designed for installation in temperature environments up to 70 °C, such as geothermal systems. Its primary use is for micro-earthquake detection and analysis.

Borehole Seismometer Observatory Grade

S62g-1.0 Model G202-1.0 is a triaxial borehole seismometer which combines low corner frequency and high-sensitivity. The S62g-1.0 features the highest in-class performance level in sensitivity, reliability and longevity for micro-earthquake detection. A single component G110-1.0 model is also available.

Borehole Seismometer

G88The Model G88-2.0 and G88-4.5 are triaxial borehole seismometers. All three orthogonal component in these models are gimbaled to give borehole deviation. The S22 series models are purpose built for long term or permanent installation in high temperature hostile boreholes.

High Resolution Strong Motion Recorders

hrsmrThe 24-bit strong montion accelerograph 130-SMA was designed specifically to meet the Department of Conservation’s California Geological Survey, Strong Motion Instrumentation Program (CSMIP) specifications for buildings and structures in urban areas.

Sensors-Broadband Seismometers

observer

The 151B series Broadband Seismometer, “Observer”, its low self noise performance makes the 151B-120 an ideal seismometer for local, regional, and global seismicity studies in different installation configurations, including observatory and portable, surface and post hole application systems

High Resolution Seismic Recorders

130-1 The 130S-01 Broadband Seismic Recorder digitizes and stores analog input from a variety of external sensors, including seismometers, accelerometers, tiltmeters and other geophysical sensors.
