  • Patent number: 10514314
    Abstract: In a sensor unit, a lower end surface of a terminal block (24) is attached to an upper end surface (12ES1) of a housing (12) by using a silicone-based adhesive in such a way as to cover an upper end surface (14ES1) of a hermetic glass (14). A covering layer (10A) made of a silicone-based adhesive is formed in a given thickness on the entire upper end surface (14ES1) of the hermetic glass (14), from which a group of input-output terminals (40ai) protrude.

  • Patent number: 10481029
    Abstract: A pressure sensor is disclosed. The pressure sensor includes a pressure sensor unit provided with a pressure detecting element configured to receive a drive voltage from a control substrate and electrically send a pressure detection signal to the control substrate so as to detect a pressure of fluid, and a plurality of electric wires connected to the pressure detecting element so as to supply the drive voltage and drawn to the outside so as to send the pressure detection signal. The pressure sensor may also include a relay substrate connected to the plurality of electric wires and having a converting circuit mounted thereon. The converting circuit converts either or both of the drive voltage supplied from the control substrate and the pressure detection signal sent to the control substrate.
