Description
AE signal generator is a device intended for stimulation of elastic fluctuations (waves) which imitate acoustic emission signals at the object under test.
It is recommended for A-Line 32D (PCI-8E) AE systems.
- Pulse amplitude up to 300 V.
- Pulse rate range from 1 to 10 Hz.
- Possibility of setting the pulse emission time.
- Operation from battery and external power source.
- Low power consumption.

Application
AE signal generator can be used together with acoustic emission system in the following cases:
- Check of AE system workability;
- Calibration of acoustic emission sensors mounted at the tested object;
- Determination of spreading speed and attenuation degree of elastic vibrations in the tested object;
- Check of correct AE computation of acoustic emission sources by means of the location coordinate system just before testing.
The AE signal generator (calibrator) is included to basic equipment sets:
- The automated diagnostic complex of side frames and spring beams of freight cars;
- The acoustic emission unit for testing oil and petrol cistern pots.
