Description

PAV preamplifier has the function of AST, and could effectively shielding electromagnetic interference and resisting impact with metal shell. It is phantom power supply, and it is compatible with most common sensors and acoustic emission acquisition boards on the market.

Main Features:

  • The PAV acoustic emission preamplifier is a broadband universal type that can be used for most common models of sensors and acoustic emission acquisition boards from various AE manufacturers
  • Fixed gain: 40dB
  • Phantom power supply, power supply carried by signal cable
  • Automatic Sensor Testing (AST) function, which can send a test signal to the sensor
  • Metal shell, shielded from electromagnetic interference, anti-shocking.

Notes:

1. The output impedance of the preamplifier must match with the input impedance of the downstream instruments (such as professional AE acquisition unit, DAQ, or oscilloscope). Otherwise it will lead to the gain of the preamplifier to deviate from the nominal gain value, resulting in signal amplitude deviation.

2. If the output of the PAV preamplifier connects to the non professional AE acquisition units (e.g. DAQ or oscilloscope), a PPS is required to supply power to the preamplifier for the PAV preamp or built-in preamp.

3. Connection must be correct. The following three wrong operations may lead to damages to the preamplifier:

       a. The input voltage is 25% higher than the power supply requirement.

       b. The input and the output of the PAV preamp are reversed connected.
