ABSTRACT:
The pressure sensitive element described has an improved barometric coefficient. The sensitive element essentially consists of a piezoelectric tuning fork having a base and a pair of arms. At the end of each arm are provided slots that are parallel to the flanks of the arms. The slots extend all the way through the thickness of the arms. The sensitive element is particularly suited for use in gas pressure measuring sensors.
