ESG provides a full range of standard and custom geophones and accelerometers. These rugged sensors are encased in watertight stainless steel housing, designed to withstand the harshest environments. Sensors are built in both uniaxial and triaxial configurations for borehole or plate type mounting.

• Designed to meet custom specifications or choose from a host of stock configurations
• Watertight stainless steel housing for maximum durability.
• Highly sensitive yet rugged design ensures reliable data integrity in any field condition.

Integrated Uniaxial Accelerometers
ESG’s accelerometers feature excellent bandwidth, dynamic range and sensitivity. Economical and easy to install, these low noise sensors are based on MEMS technology and suitable for locating seismic events in a wide variety of applications.

• A1-0.1-4.0
• A1-30-1.0
• A1-30-MSHA

Integrated Triaxial Accelerometers
ESG’s line of triaxial accelerometers capture data three-dimensionally, which means that in addition to locating an event, data from the sensor can also be used to calculate the event’s magnitude and more than a dozen other source parameters.

• A3-1.0-1.25

Uniaxial Geophones
Working at lower frequencies, ESG’s sensitive uniaxial geophones are well suited for capturing larger seismic events and lend themselves to numerous soft-rock applications.

Triaxial Geophones
Triaxial geophones are omni-directional, capturing data three-dimensionally. These geophones are specially designed to detect the kind of seismic event that might clip on higher frequency accelerometers—perfectly suited for use with the Paladin Data Acquisition System.

MEMS Capacitive Accelerometers
Based on cutting-edge MEMS Technology, these accelerometers are economical, easy to install and are ideal for monitoring both high and low frequency events. This ultra low noise and low distortion sensor offers exceptional bandwidth, dynamic range, stability, linearity and robustness. Applications include seismic monitoring, platform levelling, earthquake protection systems, intrusion detection, equipment vibration control, construction equipment monitoring, and structure modal studies.
