Abstract
PURPOSE:To improve various performances such as nonlinearity and transient temperature characteristics of a pressure transducer by forming stress concentration grooves in the reverse surface of a strain inducing plate and increasing the spring constant of the strain inducing plate. CONSTITUTION:Strain gauges 11, 11... are stuck on the opposite side (top surface side) from where the stress concentration grooves 8 and 8 are formed in the reverse surface of the strain inducing plate 10. Consequently, a diaphragm 2 deforms by receiving pressure, thereby the strain inducing plate 100 of strain inducing body 4 is deformed and the stress is generated at the inside of the strain inducing plate 10, and the stress is much larger in the part where the stress concentration grooves 8 and 8 are formed. Namely, when the stress concentration grooves 8 are formed in the strain inducing plate 10, the stress that the strain inducing plate 10 has when receiving pressure is concentrated on the part where the stress concentration grooves 8 are formed. Outputs that the strain gauges 11, 11... generate corresponding to the pressure applied to the strain inducing plate 10 increase and the sensitivity becomes excellent.
