摘要： A pressure sensor includes a diaphragm made of metal and configured to separate a pressure chamber from a liquid seal chamber, a housing made of metal and disposed around the liquid seal chamber, a pressure detection element disposed in the liquid seal chamber in a liquid sealable manner to detect the pressure of the fluid, and a potential adjustment member disposed between the pressure detection element and each of the diaphragm and the housing and being conductive, the potential adjustment member being connected to a zero potential terminal of the pressure detection element, wherein a distance between the potential adjustment member and each of the diaphragm and the housing is larger than a predetermined insulating distance.

摘要： 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.

摘要： In a pressure sensor, an electric field acting on one end surface of a sensor chip (16) is blocked by a shielding member (17), and an electric field acting on another end surface of the sensor chip (16) is removed through one end portion of a chip mounting member (18), a group of input and output terminals (40ai), and a bonding wire (Wi).

摘要： The present invention aims to provide a pressure sensor capable of improving waterproofness and airtightness by using a sealing adhesive without the use of an atmosphere-side O-ring or packing and improving workability by filling the sealing adhesive in one direction. In the pressure sensor, a protective cover is formed by any combination of a joint, a lower cover, a pressure detection unit, and a case portion. The protective cover includes a side wall forming an outer periphery and a bottom on the pressure chamber side of the side wall. An opening on a side of the protective cover opposite to the bottom is filled with the sealing adhesive to maintain waterproofness and airtightness of a signal transmission unit.
