The Model 161 series is a 4-channel signal conditioning amplifier designed to be used with piezoelectric accelerometers (IEPE or Charge) and most other piezoelectric based transducers. The Model 161 series incorporates front-panel controlled gain adjustments, multiple high-pass and low-pass filter settings, and it is capable of displaying IEEE 1451.4 TEDS information. The signal conditioner features broad bandwidth to 100kHz and 10Vpeak linear output. For various vibration applications where velocity and displacement information are desired, analog integration functions are included as output options with a push of a button. The Model 161A is 110/220VAC powered, a can be ordered with a built-in rechargeable battery option (Model 161B), perfect for field test applications.
