Material Composition
Stainless steel housing, piezoelectric ceramic element, and shielded cabling.
Structural Characteristics
Cylindrical sensor body with integrated threaded mounting base and shielded output cable.
Working Principle
Utilizes a piezoelectric crystal that generates a charge proportional to the applied mechanical force (vibration), which is then converted to a velocity-proportional voltage.
Installation Requirements
Mount rigidly to a clean, flat machined surface on the bearing housing.
Usage Precautions
Do not exceed the maximum operating temperature. Ensure the mounting surface is free of debris to maintain frequency response.
