Method and sensor device for measuring a physical parameter utilizing an oscillatory, light modulation element |
摘要 |
A light beam is transmitted by a fiber optical cable to a light modulation device such as a vibrating filament, bar or plate. This device or oscillator modulates the light intensity with a frequency which is dependent upon the physical parameter to be measured. Oscillations are sustained by a striking device. The modulated light beam is transmitted by a fiber optical cable from the measurement location to an evaluation location where the frequency of the modulated light beam is measured. The measured frequency is a function of the physical parameter.
