Process-specific parameters can be monitored at the LZH using different measurement processes and methods.

With a thermal camera or a pyrometer, the temperature of a workpiece can be monitored online. For example, a high speed camera or a spectrometer can be used to examine welding, hardening and coating processes.

The group “Machines and Controls” advises and supports the customer to identify the best-suited method, and cross-checks it with the customer-specific process.

Depending on the customer requirements, , the group “Machines and Controls” can also develop online control systems.
