DESCRIPTION:

Compact Pulser is an ultrasonic pulser/receiver that can be used as a remote pulser or a standard desktop pulser/receiver. The Compact Pulser transmits a high voltage pulse with a user specified pulse voltage and width when triggered by an external trigger signal or by the internal PRF timer. The receiver on the Compact Pulser then processes the received signal through the amplifier and the low and high filters.

For high-frequency ultrasonic inspections, the long cable from the transducer to the UT instrument may cause the signal to attenuate significantly. Because the Compact Pulser is smaller than other remote pulser/receivers, you can mount the device on the scanner near the transducer and run a long cable from the RF output of the Compact Pulser to the UT instrument. The Compact Pulser is able to preserve and drive the signal through up to 300 feet of cable.

The Compact Pulser can be triggered with a TTL trigger source as well as a pulse from other UT instrument. This feature enables you to easily integrate the Compact Pulser into your existing UT system without any extra hardware. The device can also trigger itself at rates from 10 to 5000 Hz. The trigger connector will then generate sync out pulses for other instruments.

Programmable parameters include pulse voltage, pulse width, transducer mode, trigger mode, damping resistors, gain, pulse repetition rate (PRF), high voltage switcher shut down time, and low and high pass filters. All the parameters can be controlled from a host computer through an RS232 serial communication port. The parameters can be saved in the on-board memory and can be retrieved as the default parameters when it powers up, allowing the device to function as a standalone unit.

The control program for Windows 2000/NT/XP enables you to save your settings and parameters to files and quickly load them in the future, allowing you to easily switch between applications.
