Accelerometer Selection and Connection
The following types of accelerometers can be connected to the UV-15.
Accelerometer type Sensitivity setting range
Piezoelectric accelerometer 0.100 to 99.9 pC/(m/s 2 )
Accelerometer with integrated preamplifi er 0.100 to 99.9 mV/(m/s 2 )
TEDS compliant accelerometer with integrated preamplifi er 0.100 to 99.9 mV/(m/s 2 )
Important
Before connecting or disconnecting an accel-
erometer, be sure to turn off the power supply
to the system.
