E-Z Tec DSP Metal Detector
2
What is DSP Technology?
  • DSP - Digital Signal Processing


  • Programmable device used to process and filter signals digitally



3
What are the benefits?

  • Allows us to do digital filtering


  • Provides processing power


  • Enables us to use mathematical functions


  • 3-D Processing (Magnitude, Phase and Time)


  • Improves the performance of the metal detector

Digital Filtering
29
Benefits Of Digital Filtering
  • Digital filtering helps condition/manipulate signals to help with such things as motor noise, static, and vibration.


  • Digital filtering is superior to hardware filtering because it can be changed dynamically through software.

Differences between E-Z Tec V and E-Z Tec DSP
  • Shell has flat top
  • Membrane keypad
  • Available with an analog or MPC control
  • Manually set line voltage


  • LED Bar graph
  • Commands in English


  • MPCTerm -DOS based program


  • Shell has a peaked top
  • Touch screen control
  • Digital control only


  • Automatic line voltage selection
  • Bar graph (part of display)
  • Primary language is English, operator can choose (2) secondary languages
  • E-Z Link - Windows program
37
Differences between E-Z Tec V and E-Z Tec DSP
  • Automatic product setup
  • Vibration phase setting is always “O”
  • Consolidated power supply with control
  • Can adjust the settings for a product while another one is running
  • When product speed is selected, filters are automatically set through software rather than jumpers


  • Manual product setup
  • Vibration phase setting is different on each unit
  • Separate power supply


  • Can not edit a different product while another one is running


  • Modifying a product speed required changing jumpers
