22-bit Strong Motion Industrial Recorder
Model SMR-6102-I

The PMD/eentec SMR-6102-I is a rack mountable, rugged, ultra low power, high-performance, versatile 22-bit resolution strong motion recording system

The standard system is configured for 8-channels. Optional configurations include configurations up to 32 channels. All channels operate synchronously up to 2,000 samples per second.

A standard 10Gb removable hard disk is included, with optional disk capacities to to 32Gb. Data is retrieved by removal of the PC compatible compact hard drive, or through dial up telephone access (internal modem optional), via LAN (Ethernet card optional), or wireless LAN.

The SMR-6102-I 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.

Optional rack modules include sensor receiver module, calibration module, power supply module, and remote control module.

This configuration is used for permanent building, bridge, or dam monitoring.
