Guralp CMG-5T Accelerometers

The CMG-5T accelerometer is a three axis strong motion force feedback accelerometer in a sealed case. The sensor system is self-contained except for the power source. An internal dc-dc converter ensures a completely isolated sensor system and allows the system to operate from 10 to 36 Volts. The CMG-5T sensor system has an extremely large dynamic range. Full-scale low-gain sensitivity is user-adjustable from 2.0 g down to 0.1 g with an external resistor on each axis. The standard frequency pass band is flat to acceleration from dc to 100 Hz. Other low pass corners from 50 Hz to 100 Hz can be ordered. A high frequency option provides flat acceleration from dc to 200 Hz. CMG-5TB is the borehole version of this sensor.
