|
The SMR-6102 is a rugged, low power, high-performance, versatile
22-bit resolution multichannel digital strong motion recording system
for permanent monitoring installations
The standard system is configured for 4-channels. Optional configurations
include configurations up to 32 channels. All channels operate synchronously
up to 2,000 samples per second.
A standard 128Mb removable flash disk is included, with optional
disk capacities to to 1Gb. Data is retrieved by removal of the compact
flash disk, or through dial up telephone access (internal modem
optional), or via LAN (Ethernet card optional).
The SMR-6102-x includes a GPS receiver and antenna and "Smart Timing"
software, allowing the user to select the timing accuracy, which will
automatically control and minimize the GPS cycling times. The integrated
display and keyboard allows for easy setup in the field and real time
viewing of up to 3 waveforms.
For applications such as bridge or dam monitoring requiring optional
sensor drivers and protection with remote calibration and reset, see
