The rugged seismograph

The ABEM Terraloc Pro 2 is a tough and versatile seismograph for geotechnical and structural assessment, geological survey and environmental studies. Common applications include locating bedrock and determining its strength, predicting the stability of materials ahead of construction, pile and foundation testing, and traditional geological mapping and exploration work.

Application Areas 

Ground investigation

A wide range of geotechnical information can be gathered using seismic methods: depth to bedrock, recording the strength and stability of materials, void location, and earthquake resilience are among the most common applications. Additionally, seismic velocities can be converted into common engineering parameters to provide a quantifiable result.

Geological exploration

Seismic survey has been used to map geological formations for many decades, most commonly by collecting refraction and reflection data. Tasks such as finding the contact between two different geological units, sequencing of layers, mapping structures and faults, and mineral exploration are well documented uses for seismic methods.

Borehole

Receivers and/or sources can be used within boreholes for uphole, downhole, crosshole and tomography surveys; this approach provides detail that is unachievable from surface measurement alone. Borehole accessories integrate directly with the Terraloc and can also be used to investigate specific subsurface structures such as concrete piles or foundations.

A RUGGED STANDALONE SYSTEM FOR SURVEY ANYWHERE

IP66 protection, no need for an external computer and set-up wizards take the stress out of survey.

A core principle for ABEM is to make dependable, easy to use instruments. A set-up wizard will help you get the right settings and surveys can be completed using only the instrument keypad: no PC, no peripherals, just the Terraloc, spread cables and geophones. This allows for efficient fieldwork with IP66 protection maintained throughout the survey.

DESIGNED WITH A FOCUS ON DATA QUALITY

Independent receiver circuits on every channel provide market leading data quality.

Outstanding dynamic range from high specification digitizers with selectable voltage ranges ensures the ABEM Terraloc Pro 2 is able to record everything from ‘a whisper to an explosion’. Isolated receiver circuits significantly reduce noise and on-board filtering and analysis tools provide efficient in-field quality assurance so there are no surprises upon returning to the office.

VERSATILE AND SCALEABLE

The ABEM Terraloc Pro 2 offers the flexibility to undertake reflection, refraction, surface wave and borehole surveys with a scaleable hardware design to perfectly meet your needs.

Available in 12, 24 or 48 channel versions, these instruments can be upgraded to grow with your changing requirements. If you have two or more instruments, they can operate independently or be interconnected to further increase channel numbers when big projects come up. The system can operate with any type of seismic accessory to work in the widest range of applications.

Accessories

ABEM Power Adapter

Robust and stable power in the field

This powerful AC-DC adapter allows operators to run their ABEM instruments from an existing power network or a small ‘suitcase’-style generator. These generators weigh less than a typical high-capacity lead-acid battery, providing an option for prolonged power even in locations where recharging of batteries may be problematic. The ABEM Power Adapter is perfect for demanding field campaigns; it is fully waterproof and capable of providing a clean and stable 12V DC supply in excess of 30A from a 110V/230V AC (50 or 60 Hz) source. It would also suit monitoring and other unattended applications where there would be limited opportunities for changing over batteries.

In addition to the main power output, a waterproof auxiliary connector offers both 5V 2A and 12V 1A outputs, for custom accessories, plus an “operation OK” signal, useful for remote applications.

There are two versions of the ABEM Power Adapter: one is compatible with the original Terrameter LS and Terraloc Pro, whilst the other is compatible with the current Terrameter LS 2 and Terraloc Pro 2.

 

ABEM Transport Case

Transport and store your instrument securely

Protect your equipment in even the toughest of conditions. With the ABEM Transport Case you can be sure that your Terraloc Pro 2 is safely stored during transportation to and from the field. Industry-leading materials ensure a rugged dust and water proof case that can withstand the test of weather and time.

ABEM Wire-free trigger

Wire-free triggering for Terraloc products

Product specification: ABEM Wire-free trigger – PDF

The Seismic Radio Trigger provides an easy, cost-effective solution for wireless triggering of the Terraloc family of products, being compatible with Terraloc Mk 8 to Terraloc Pro 2 instruments. It can trigger manually on a single button press or communicate a trigger signal from another device. The system operates on license-free Lo-Ra frequencies and should be compatible with almost any source and trigger system.

ABEM Terraloc Interconnect Accessories

Flexibility when you need it

For bigger projects, when more channels are required, multiple Terraloc units can be joined together to operate as one system. Arming and triggering can be handled and distributed from just one of the machines via lightweight interconnect cabling. It is possible to interconnect Terraloc Mk 8, Terraloc Pro and Terraloc Pro 2 instruments to form the hybrid system, making good use of even the older instruments in your fleet.

WEBINAR

An introduction to MASW for ground investigation

This short webinar will introduce MASW (multichannel analysis of surface waves) as an efficient tool for site assessment to determine ground stability, depth to bedrock and bedrock quality, among other things. The presentation will be aimed at those who are new to the method and will cover the basic principles of MASW, considerations for survey design, general processing workflow, and what the final results can tell us about the subsurface, illustrated by a small number of cases. The webinar will be hosted by Harry Higgs, one of Guideline Geo’s Application Engineers.

 

Seismic methods are not just useful for traditional geological exploration; analysis of seismic motion is an invaluable engineering tool to map the location and nature of bedrock and predict the strength and stability of materials.
