Abstract
PURPOSE: To solve problems and provide a detector of a small size, good sensitivity and stable characteristics by sealing and fixing piezoelectric element parts in a case with a sealant, fixing one end of a force receiver to the case and detecting the force acting upon the force receiver as stress.
CONSTITUTION: A force receiver 2' is of circular cylindrical form and its flange part 21' side is fixed to a case 1. The pressure of the measurement pressure P shown by the arrow is transmitted via sealent 4 to peizoelectric element parts 3. Stresses in mutually opposite directions with the central axis of the force receiver 2' in-between are generated and the electric signals corresponding to the stresses are generated in the respective piezoelectric element parts 3a, 3b. The signals are processed in the electric circuit of high input impedance, whereby the measurement pressre P may be detected. Twice larger signals are obtainable through differential processing of the outputs of the piezoelectric element parts. The measurement pressure P may be expanded by the length l of the force receiver and may be detected by the element parts 3 with good sensitivity. It is also possible to separate the case portion 1 from the measurement place by increasing the length of the force receiver and to perform measruement of high temperature places
