A set of hardsteel probes, custom designed for each product, mounted on the MultiBorescope unit, is inserted into the casting by operator manually. Each probe includes NanoCameras and/or LightThru transmitters/receivers, to fulfil the measurement scope.

Measurement is triggered by operator using a button directly on the probe. Control LED signalizes the measurement cycle. The probe is connected to the control and visualization computer using one or more control cables using PoE interface.

By measuring the signal between selected transmitter-receiver pairs and/or image processing from NanoCameras, the system evaluates whether the passability of that part of the casting meets expected quality criteria, or if the part is damaged. The results are displayed on the computer screen with precise localization of the defect.

In front-light configuration, they work the same as visual inspection done by operators with lots of different image processing functions for full automation of the process.

In back-light configuration, the LED is located at the opposite end of the channel. This allows to measure the overall size of the channel cross-section. It is possible to measure also slightly bended channels with no direct visibility between camera and LED.
