Seismic Monitoring Systems Questionnaire

We offer a full range of seismic-monitoring and dynamic-measuring sensors and instruments.

Our products include velocity sensors, accelerometers, strong motion recorders, seismic digitizers, software, and accessories. These products are used to perform a wide variety of functions, including structural monitoring and critical vibration alarm. Accelerographs or central recorders are installed in nuclear plants, dams, bridges, tunnels, tanks, above-ground reservoirs, tall buildings, historical buildings, base-isolated buildings, and buildings that house vital or critical functions. Seismographs are used to study earthquakes and other life-threatening earth movements. Seismic switches and alarm systems are used to help control elevators, escalators, fire-station doors, generators, machinery, trains, toxic gases or fluids, and pipelines at vulnerable locations such as fault or river crossings.

Network solutions range from three-instrument networks for tall buildings, to central recorders with 20-50 channels of data for heavily instrumented buildings, to complex regional or national networks involving numerous instruments and a mixture of satellite, radio, cellular, or telephone modems. Data may be streamed continuously into a central recording system, or triggered event data may be transmitted to a central system.

We can arrange qualified installation, maintenance, and training anywhere in the United States. We also distribute these products in many Latin American countries.
