Title:
THROWAWAY PRESSURE TRANSDUCER AND THROWAWAY PRESSURE TRANSDUCING DEVICE
Document Type and Number:
Japanese Patent JPH02167441
Kind Code:
A
Abstract:
PURPOSE:To decrease assembly man-hours and simplify operation, and to improve measurement performance by constituting the center part of pressure transduction in a sensor assembly state. CONSTITUTION:A sensor assembly 12 is incorporated in a housing 11, and a sensor chip 18 is adhered directly to an insulating substrate 19 and connected to the electric connection terminal of the substrate 19; and a coupling lid 20 is adhered to the substrate 19 and a pressure transmission medium 21 is charged in the coupling lid 20. Then the internal space of the coupling lid 20 surrounding the chip 18 of the substrate 19 becomes a simple space having no projecting body and the pressure transmission characteristics can be improved without leaving any air when the medium 21 is charged. Further, no air enters a living body and safety is obtained. Further, the assembly 12 can be constituted in the assembly state with a small number of components such as the chip 18, substrate 19, and coupling lid 20, etc., while the center part of the pressure transduction is constituted. Therefore, the assembly man-hours and operability are simplified and the measurement performance can be improved.
