Features of the Ring Piezoelectric Sensor on Terminal Crimping Machines
Publication date：2026-10-13 00:19
Core working principle of the ring piezoelectric sensor: it utilizes piezoelectric quartz crystal material's property that when subjected to mechanical stress, a charge proportional to the stress is generated inside it. The ring sensor uses this principle: when an external force acts on its ring surface, it produces a corresponding electrical signal output.

Ring Piezoelectric Sensors in Terminal Machine Applications

Main Features and Advantages
  1. Center through-hole design: this is its most notable feature, allowing cables, shafts, bolts, etc. to pass through, enabling in-situ, online measurement without changing the original structure.
  2. High stiffness: it deforms very little and has a very high natural frequency, making it very suitable for measuring dynamic force, while measuring static force requires a special charge amplifier.
  3. High sensitivity and high resolution: it can detect tiny changes in force or pressure.
  4. Wide dynamic range: it can measure weak vibrations as well as withstand large impact loads.
  5. Rugged and durable: it is usually encapsulated in sturdy alloy material, suitable for harsh industrial environments.
