摘要：

Transducers using optical-fibre methods for transmitting the value of a measurand can show great advantages over more conventional devices. This is particularly the case where the primary sensing element is digital in nature, such as in a resonant double-ended tuning fork (DETF) force transducer. A DETF has been used to produce a hybrid optoelectronic pressure transducer with such properties. Results are given and show that the device has a 2.5 bar range, a sensitivity of 525 Hz/bar, and a repeatability of 0.1% of the full-scale range.
