Pocket AE-2

No items found.

The Pocket AE-2 is a high performance, computerized, dual-channel Acoustic Emission (AE) system which is packed in a robust, portable handheld unit optimal for field use. The Pocket AE-2 offers all the performance, capabilities and features of larger, more expensive MISTRAS’ AE system (wide bandwidth, speed, AE features, sampling rates, waveform processing, audible AE) in a compact, battery-operated package. Ideal for situations when power is not readily available; the Pocket AE is equally useful in the laboratory with two-channel capabilities and 1 channel parametric input. Its portability and versatile features make it ideal for leak detection, material and processes characterization, and screening for more detailed follow-up inspection.

Features

  • All the standard performance features as in PAC’s PCI based multi-channel AE system.
  • Hand-held portability for quick, efficient testing in the field or laboratory.
  • PDA type computer using Microsoft™ Windows-CE™ compact operating system, familiar and easy to use.
  • Utilizes PAC standard low-cost passive AE low power sensors with an internal AE preamplifier.
  • Two AE channels with one high performance 18 bit A/D for each channel, allowing AE data processing at up to 10 MSPS.
  • 16 bit A/D waveform capture and AE signal processing offers wide AE system dynamic range without the need for gain controls.
  • 16 bit A/D parametric input to correlate AE to other process sensors.
  • Integrated rechargeable battery package lasting 4 hours (continuous) or more. Batteries are easily changed and can be charged outside of the AE system (with optional charger).
  • Numerical keyboard with function keys for quick, easy setup and control.
  • Internal flash memory for storing setups and data files.
  • Permanent digital record of the test results in standard DTA, PAC data files, compatible with AEwinTM Software for detailed data analysis and data visualization.
  • Compact Flash card and USB port for data transfer to laptop or desktop PC.
