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, Delcom’s productivity software is a very valuable tool. Delcom's powerful software has many useful features, allowing users to set pass/fail thresholds, monitor multiple sensors at once, save data for further analysis, and more. It is designed to make common tasks as fluid, intuitive, and easy as possible. The software requires a PC running Windows XP or newer OS.
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 12 sensors. A user may want to purchase additional sensors in order to increase the range of the entire system or to take measurements at two or more physical locations.
The sensor is designed to be used without a stage. However, a stage is recommended for applications requiring a high level of precision. The stage will keep the elevation of the conductive layer consistent in the sensor gap and allow for better xy positioning of the material within the sensor.
The sensor is vacuum ready; however, optional vacuum-ready cabling, brackets, and feedthrough(s) will be required for vacuum applications.
Delcom can source a laptop, desktop, tablet, or industrial touchpanel PC for customers, if needed.
