Non-Contact Sheet Resistance Instrumentation

30C9 Inline Sheet Resistance Meters

multiple eddy current sensors measure Ohms/sq inline, in real time, and without contact eddy current sensor measuring sheet resistance of a thin film in a vacuum coater inline software to record sheet resistance of web of material in real time

Inline Non-Contact Eddy Current Resistivity Meters for Glass and thick films

  • Non-contact measurement of Ohms/sq, Ohms-cm, resistivity, thickness, and more
  • Great for monitoring cross-web and down-web consistency
  • Monitor and control 3 or more sensors with one system
  • Works in vacuum or atmosphere, wet or dry processes
  • Choose sensors in one of four ranges from .005 Ohms/sq to 100,000 Ohms/sq—add other sensors later
  • Real time monitoring of moving materials via PC or LAN

Four Ranges to Choose From

Up to 4.5 significant digits available, depending on instrument range:

Options and upgrades

All options and upgrades are available for purchase with the original unit and for at least one year after purchase.

  • Vacuum ready package:

    The sensor is vacuum ready; however, for vacuum applications optional vacuum-ready cabling, brackets, and feedthrough(s) will be required.

  • Optional computer:

    Delcom can source a laptop, desktop, tablet, or industrial touchpanel PC for customers, if needed.
