|Seismic Recorders & Digitizers, Switches, Alarms, & Sensors
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.
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.
