Description

The Model 600 Pulser can be used to provide high voltage pulses to an AE transducer for the purpose of simulating AE from crack growth at a particular location. It can be powered by a laboratory DC power supply with +15 volts DC.



Power can also be supplied via a BNC connector at the rear of more recent versions of the AESMART 2000 hardware unit, or by connection to the trigger channel of a MUX-MODULE. The pulser can also be powered with the model 600B companion battery pack.



Two levels of voltage and an off position are selectable via a three position switch. Selectable voltage levels are 150 volts and 400 volts. Selection of the 150 volt position into a DECI SE25-P transducer as a transmitter gives signal levels comparable to the breaking of a 0.5mm pentil pencil lead.



The use of this combination with the SE25-P transducer mounted on the edge of the plate in a structure under tests provides IP signals to test the efficiency of HF/LF ratio filtering in eliminating extraneous noise while still having the capability of detecting crack growth signals in the structure. When a voltage position is selected pulses of the selected voltage are output at 1 second intervals.
