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.

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.
