DEVICE FOR MEASURING PRESSURE AND TEMPERATURE IN INTAKE MANIFOLD OF INTERNAL COMBUSTION ENGINE AND METHOD OF MANUFACTURE OF SUCH DEVICE Russian patent published in 2002 - IPC

FIELD: measurement technology. SUBSTANCE: proposed device has temperature transmitter arranged in one housing with pressure transmitter. Said housing is secured together with processing circuit on one base practically without deformation. According to invention, housing consists of at least two chambers separated from each other, one of which forms measured pressure chamber communicating through branch pipe with intake manifold and insulated from ambient medium. This chamber accommodates the part of base on which pressure transmitter is secured. Other chamber serves for accommodating and fastening the rest of base with contact terminals. Additional glue joints are provided for fastening the base and sealing pressure transmitter and relieving mechanical stresses. EFFECT: improved accuracy of measurements and simplified design of device. 5 cl, 4 dwg
