Abstract
Official abstract text for this publication.
The invention prevents a pressure receiving space of a pressure sensor from being electrically charged. In a pressure sensor, a diaphragm is attached to a base which is fixed within a cover and a pressure receiving space in which an oil is sealed is formed. A semiconductor type pressure detecting device is connected to a plurality of terminal pins by a bonding wire. A neutralization plate attached to a periphery of the semiconductor type pressure detecting device or a part of the periphery thereof is connected to an earth terminal pin by an earth bonding wire, or is connected to the earth terminal pin by a soldering so as to prevent an insulative medium sealed within the pressure receiving space from being electrically charged.
First claim
Opening claim text (preview).
What is claimed is: 1. A pressure sensor comprising: a diaphragm which receives a pressure of a fluid; a semiconductor type pressure detecting device which is provided with a plurality of bonding pads including an earth pad; a base which forms in relation to said diaphragm a pressure receiving space in which an insulative medium is sealed, and is provided within said pressure receiving space with said semiconductor type pressure detecting device; and a plurality of terminal…
