| Product Overview
The WCPE200 series ring-type piezoelectric sensor is a ring-type piezoelectric force sensor independently developed by winchen sensor, with a measuring range of 0~20KN, able to accurately measure dynamic force changes from low to high loads, designed for dynamic pressure monitoring of terminal crimping machines and comparable to imported brands. It uses a highly stable quartz crystal as the sensing element, offering ultra-high rigidity and excellent linear output characteristics, and can convert mechanical stress directly into a high-fidelity charge signal; combined with a charge amplifier, it captures the force waveform of every crimp in real time and with high accuracy. It has an overall ring structure that is easy to mount directly on the stamping spindle of a terminal crimping machine, making it a key component for improving crimping yield and enabling intelligent error prevention.
| Features
1. High dynamic response: the quartz crystal outputs a charge signal directly with no mechanical hysteresis, accurately capturing instantaneous force changes (such as impact, vibration and high-speed crimping).;
2. Ultra-thin compact design: integrated cable structure, only 4mm thick, suitable for space-constrained installation environments.
3. Ring structure, easy to integrate: the central through-hole design allows it to be threaded directly onto the crimping spindle, for compact installation without changing the original mechanical structure;
4. High stiffness and low non-linearity: minimal deformation ensures the rigidity of the force transmission path, with non-linearity better than 2%F.S.;
5. Resists eccentric loads and interference: special crystal cutting and structural design effectively suppress the effects of lateral force and bending moment;
6. Reliable and durable: stainless steel housing, fully sealed welding, IP67 protection rating, suitable for oily and vibrating industrial environments;
7. Low zero drift, high repeatability: strict aging and temperature compensation ensure consistent and reliable long-term data;

| Applications
1. Wire harness terminal crimping machines: real-time monitoring of the force-displacement curve of every crimp; through peak force or waveform envelope analysis, it automatically identifies defects such as missing strands, over- or under-crimping and terminal deformation.
2. Fully automatic crimping production lines: linked with the PLC for high-speed in-line pressure monitoring and immediate sorting of defective parts.
3. Contact riveting machines: monitors the riveting pressure of switch contacts to ensure consistent contact resistance.
4. Resistance welding / ultrasonic welding: used as auxiliary force monitoring to precisely control dynamic pressure during welding.
5. Precision stamping and assembly: used to monitor small dynamic force changes such as stamping loads and spring assembly forces for fault warning.
