Resilience and displacement measuring device and method |
摘要 |
A resilience and displacement measuring device is configured with a shaft having a displacement detection module and a force detection module disposed respectively at the two ends thereof. When the shaft is moved for driving a probe of the force detection module to press on a tested press-key, a reflective panel in the displacement detection module will be caused to displace along with the moving of the shaft for allowing a light sensor to measure the displacement of the shaft, and at the same time the pressing of the probe on the press-key will force a detection film to deform for allowing a strain gauge to measure a resilience. The device is capable of dividing a measurement range into a plurality of sub-ranges while designing calculation models specifically for the sub-ranges, by that a precise distance can be obtained from the measured distance information of the calculation models. |
