Broadband versatility and gain selectable 20/40/60 dB preamplifier
for acoustic emission equipment
Product description:
1.PAS AE preamplifier series are wideband -universal 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: sigle-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.
| Interface function | |
 | Output terminal: amplified signal output, phantom power input Power input: 24V—32V, 100mA DC input, positive inside and negative
outside Filter knob: the white scale corresponds to the reserved signal
frequency band Gain gear selection: the three gear positions correspond to 40dB
(100 times), 20dB (10 times), and 60dB (1000 times) amplification
respectively |
 | Both differential input and single-ended input refer to the signal
output type of the acoustic emission sensor, and the stay side of
the input selection toggle switch is the currently selected
interface The input signals are all analog oscillating voltage signals |

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.
