OPTICHECK technology built-in

Every measuring device with OPTICHECK technology built-in is able to provide a reliable statement about the correct function of the device at any time. The technology uses continuously executed test routines to cyclically compare the current device condition against its baseline performance at time of delivery. In addition to the general monitoring of output signals, power supply and circuits, this includes numerous device-specific function tests.

For the operator, the permanent self-monitoring is translated into standardised status signals in accordance with NAMUR NE 107. These status signals provide clear and comprehensible descriptions of the current device situation and provide a quick overview of error events. The error information can be immediately signalled to the control room via a defined error current or via error signals. This provides operators with condition-based information about the measuring devices in real time. Appropriate measures can be derived from this. All data is also logged in the measuring device and, in case of doubt, is available for a more in-depth root cause analysis.

The continuously running self-diagnosis of OPTICHECK technology built-in also forms the basis for rapid on-site verification of the measuring devices. Regardless of whether the status of software and hardware components is to be routinely checked and documented or carried out as part of troubleshooting, detailed verification reports on the health status of the instrumentation can be generated directly on site or in the control room. The measuring devices can be checked without interrupting the process and are ready for reporting at the touch of a button. Depending on the device type, this verification option can be performed wirelessly via Bluetooth using the OPTICHECK Mobile app on site at the field device or from the control room using the OPTICHECK DTM.

In addition to comprehensive device diagnostics, OPTICHECK technology built-in stands for a wide range of device-specific application diagnostics that provide a deep insight into your own processes and systems. This measurement and device data is always available to operators to optimise and control processes. They also provide information that can be used for predictive system maintenance. OPTICHECK technology built-in utilises the device-specific data in numerous KROHNE measuring devices for meaningful application diagnostics.
