Description

The Model 602 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. 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 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.



Four intervals are selectable via a rotary switch. Selectable intervals are 8.3 ms, 10.00ms, 16.6ms, 20.0 ms, 33.3ms, 40.0ms When a voltage position is selected, pulses of the selected voltage are output at the selected intervals.
