Abstract

This paper describes the principles and characteristics of some symmetrical 'double-ended tuning fork' resonators (machined from elinvar alloy or etched from quartz crystal), and their applications as force/pressure transducers. The temperature coefficient and drift can be made quite small, and the output signal - frequency- can be measured easily and precisely. A microprocessor linearises transducer characteristics - linearity was within 0.001% of span for elinvar transducers.
