The core working principle of the annular piezoelectric sensor is to use piezoelectric quartz crystal material to generate charges proportional to the stress when subjected to mechanical stress. A ring sensor utilizes this principle, and when an external force acts on its ring surface, it produces a corresponding electrical signal output.
Main features and advantages
-
Central through-hole design: This is its most prominent feature, allowing cables, shafts, bolts, etc. to pass through it, achieving in-situ and online measurement without changing the original structure.
-
High stiffness: With minimal deformation and high natural frequency, it is very suitable for measuring dynamic forces, while measuring static forces requires special charge amplifiers.
-
High sensitivity and resolution: capable of detecting small changes in force or pressure.
-
Wide dynamic range: capable of measuring weak vibrations and withstanding large impact loads.
-
Durable and sturdy: typically encapsulated in sturdy alloy materials, suitable for harsh industrial environments.
