Earthquake measurement and response

The EQR90 and ERQ120 accelerographs are a new generation hardware package, combining the credibililty of proven CSI data aquisition and processing software.  We designed and developed the EQResponder range from scratch, to target the economical delivery of truly useful site-specific information.

The EQR90 is the "best-in-class" low-cost accelerograph, measuring from just below human perceivable shaking to beyond damaging shaking  It has been specifically targeted toward providing information relevant to the interaction between earthquakes and the built environment, without the cost penalty of 'wasted' sensitivity measuring shaking that has no effect on our built enviroment.

Compared to traditional solutions, the EQR90 offers an order of magnitude reduction in total installed cost, or an order of magnitude increase in measurement points for the same project budget.

The EQR120 is an extended dynamic range accelerograph, suitable for earthquake science studies or high-end structural dynamics, such as advanced building state-of-health analysis.

As with the EQR90, the EQR120 has been designed to offer performance comparable to traditional high-end accelerographs at a significantly reduced total installation cost by the use of latest generation technology and leveraging our experience in providing end-to-end solutions.

Structure dynamics

Earthquake - enviromental - compliance monitoring

EQR-C central recorder - complex data aquisition that's easy and really works - now there's a difference! 

Building on our experience with the CUSP-Ms and CUSP-Me, we have designed a next-generation integrated package that delivers the maximum possible flexibility in terms of sensor types and communication options with easiest installation and configuration for your structure dynamics project. 

  • Install EQR120s to measure ambient vibrations for structure characterisation using low-level ambient energy sources including wind and traffic.
  • Install some ERQ90s to capture response spectra date for real-time damage estimates.
  • How about some wave height radars and laser rangefinders in combination EQR120s to characterise your floating bridge?
  • See how your building performs in wind storms with anemometers and EQR120s
  • Measure the humidity and see how your wooden frame building performs over the wet winter months.
  • Monitor cracks in your dam to stay on top of risk

Using the EQR-C central recorder, you can build seamless and scalable sensing solutions.  All the data you need in one synchronised dataset using native units.  Could it be easier?

The EQR-D digitiser even allows you to connect your own sensors with a wide range of input types including voltage and 4-20mA current loops.

All the sensing nodes in the system also include synchronised time stamping and months of data buffering for maximised resilience.

The combinations are endless! 

We help you get there with mix-and-match sensors, smart central recorders and flexible communications.  Gone are the days when the installation cost outweighed the equipment costs.  Chose your type of sensor, pick a spot, drop it down, and let our smart communications system make your life easy.
