Functional Description

This probe system delivers accurate static position and dynamic vibration measurements, ensuring early detection of mechanical issues such as misalignment, imbalance, and bearing wear. Its slim-profile Proximitor Sensor supports DIN-rail and panel mounting, while SpringLoc terminals and ClickLoc connectors simplify installation and prevent loosening. Enhanced RFI/EMI immunity ensures compliance with CE standards without additional shielding.

Optional ETR (Extended Temperature Range) probes and cables allow operation in extreme environments up to 260°C, making this system suitable for turbines, compressors, and other high-value rotating equipment. Full component interchangeability with other 3300 series transducers reduces maintenance complexity and ensures backward compatibility.
