DIFFERENTIAL PRESSURE TRANSDUCER |
摘要 |
A differential pressure transducer utilizing a transformer and a means for maintaining a constant voltage sum on the secondary leads of the transformer to eliminate errors due to spurious electrical impulses in the transducer. The extensible end of a bellows moves a magnetically permeable core with respect to the transformer, thereby inducing different voltages on separate secondary loops longitudinally spaced along the transformer.
