    Accelerometer Selection and Connection Accelerometer Mounting The UV-16 is a vibration measurement amplifi er designed for use with piezoelectric accelerometer or accelerometer with integrated preamplifi er. Other types of accelerometers such as electrokinetic accelerometers cannot be used with this product. Choose a suitable accelerometer according to the measurement requirements including measurement range, frequency range, and environmental conditions.
  • Page 34 Accelerometer Selection and Connection WARNING When performing measurements on ma- chinery with exposed rotating parts or drive train parts, proceed with utmost caution to avoid the risk of getting caught in the machinery. Note Tighten the M6 screw fi rst on the piezoelectric ac- celerometer side and then mount the rod attachment.
