PAS Acoustic Emission Preamplifier
Product description:
1.PAS AE preamplifier series are wideband models, which can match
with most common sensor models and AE acquisition cards for each
factory;
2.Three gain gears to choose: 20/40/60dB;
3. Two input ways: single-ended/difference;
4.Two kinds of power supply modes: phantom power supply, the power
supply is carried by the signal line; or direct power supply from
external power supply;
5.Built-in filter, relevant frequency are divided to four gears ;
6.Be equipped with protection capacity against electric shock and
recoverability anti-blocking phenomenon;
7.AST (Automatic sensor test) function, can send out test signal
resource to the sensors ( under the condition of phantom power
supply);
8. Metal shell, shield electromagnetic interference ,resist shock.

Note:1. The power supply should be a good match with the output
impedance, otherwise it will lead to the gain of the preamplifier to deviate from the nominal gain value, resulting
in signal amplitude deviation. 2. If AE board from other manufacturers are selected, a PPS preamplifier power supply is required. 3. Wiring must be correct. The following three wrong operations may
lead to damage to the preamplifier: a. The input voltage is 25% higher than the power supply
requirement. b. Connect the power supply to the signal input connector. c. The positive and negative terminals of the powersupply are
inversely connected |

Performance characteristics:
● The PAS preamplifier is a broadband universal type, which can be
applied to most common types of sensors and acoustic emission
acquisition cards from various manufacturers;
● The pre-amp gain has three options of 20/40/60dB;
● Two signal input methods, single-ended/differential;
● Two power supply modes are available: phantom power supply, which
is carried and supplied by the signal line; or direct power supply
from an external power supply.
● Built-in filter, the corresponding frequency is divided into 4
gears for selection;
● It has the ability to protect against electric shock and the
ability to recover from blocking phenomenon;
● Automatic sensor test (AST) function, which can send out a test
signal source to the sensor (in the case of phantom power supply);
● Metal shell, shielding electromagnetic interference, anti-shock.
