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