Non-Contact Sheet Resistance Instrumentation

30C9 Sheet resistance meter

eddy current sensor measuring silicon wafer eddy current sensor with automated software eddy current precision measurement inline eddy current meter

Non-Contact Eddy Current Resistivity Meter for Thick Materials

  • Non-contact measurement of Ohms/sq, Ohms-cm, resistivity, thickness, and more
  • For coated glass, photovoltaic solar, vacuum metalized components, windscreens, and more
  • Choose a sensor in one of four ranges, from .005 Ohms/sq to 100,000 Ohms/sq—add other sensors later
  • For benchtop or inspection station applications
  • Simple one-button operation
  • Small footprint with detached sensor probe
  • Options include vacuum-ready probe, PC-based productivity software, Ethernet connectivity, stage, and more

Options and upgrades

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

  • PC based software upgrade:

    This configuration does not require software for operation; however, the user can upgrade to Delcom’s productivity software for at least one year after initial purchase. The software requires a PC running Windows XP or newer OS. Delcom's software is designed to make common tasks as fluid, intuitive, and easy as possible.

  • Ethernet connectivity upgrade:

    This option is for integration with a PLC or other process control systems. It enables full remote read and control of up to six sensors via Ethernet. It also includes a fully functional website for diagnostics and setup.

  • Additional sensors:

    The 873 interface module can accommodate up to three sensors. A user may want to purchase additional sensors in order to increase the range of the entire system or to make measurements at two or more physical locations.

  • 30C9 stage:

    The sensor is designed to be used without a stage. However, for applications requiring a high level of precision we recommend a stage. The stage will hold the elevation of the conductive layer in the sensor gap and allow for better XY positioning of the material under the sensor.

  • 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.
