    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.
