The Multi Sensor Rack (MSR) is an efficient and flexible probe and sensor changer for bridge type cmms. By choosing which sensor and probe sockets to mount, the new MSR types can be configured easily to your requirements. This allows total flexibility for future extensions of your cmm. The sensor change is passive, i. e. the cmm handles the change of the probe configurations. For this purpose, the MSR is placed inside the measuring range of the cmm. (Probe sockets are not included).
