Type EDK 93

  • Four Channel
  • Linearity 0.01 %
  • Resolution 0.01 μm
  • Mass Data Store

EDK 93 is a compact, four channel, high accuracy measuring station that can be operated remote from any computer and power source with ability to store up to 6000 measured values. If operating away from a power source the optional internal battery pack will provide eight hours of continuous operation. Other options include a real time clock for use in data acquisition and storage. The digital display is a high efficiency LED 14mm, 5 ½ digit. When using a custom engineered program, an 8 digit alphanumeric display is available. EDK 93 has 6 output lines (3 on the standard model) and 3 input lines. Internal relays provide limit outputs both high and low while a further 15 levels of visual tolerance are displayed on the front panel. Transducers are matched to the system having conditioning and linearising components assembled in the DB9 connector providing a system linearity of 0.01% when using transducers up to +/-5mm range. Sampling of channels is carried out in pairs where each pair is simultaneously scanned. The System can operate directly with a computer or can perform tasks remotely storing data for later analysis if needed.
