摘要:
A sensing system including a sensing device (1) with cooperating electrical components (40, 41) which move relative to each other in response to a sensed environmental parameter to yield a reactance signal, which is transmitted to a remotely located processor having an oscillator for receiving the transmitted signal and generating a transduced signal whose value corresponds to the value of the environmental parameter.
摘要:
Le détecteur, servant à détecter la pression d'un milieu, utilise au moins un élément modifiant sa valeur de résistance sous l'effet de la pression. Cet élément est un élément résistif courant, de préférence une résistance à couche de charbon, une résistance à couche mince ou une résistance à couche épaisse. Les éléments (21) sont de préférence disposés dans un circuit en pont dans lequel, afin de compenser les influences de la température et d'accroître le signal dépendant de la pression, on utilise des éléments résistifs ayant des coefficients de température et de pression différents. Les éléments résistifs sont en outre disposés sur un support (32) pouvant se déformer élastiquement sous l'effet de la pression, de manière à obtenir un accroissement du signal par l'effet conjoint de la pression ainsi que d'une dilatation, respectivement d'une déformation de l'élément résistif.

A detector is provided by coating a fluid conductive material on a flat portion of a diaphragm. The detector includes: a resistor element (3); resistor element electrodes (4), which are overlapped and connected with mutually opposed parts of the resistor element (3); and a linear conductor connected with the resistor element electrodes (4). The resistor element electrodes (4) each include: a linear portion (40S) having a linear inner side facing an inner side of paired one of the resistor element electrodes (4); and peripheral portions (40E) defined at both ends of the linear portion (40S), at least one of the peripheral portions (40E) being connected with the linear conductor. All of the linear portions (40S) are arranged so that inner sides (40L) are arranged mutually in parallel. The resistor element (3) is connected with the linear portion (40S). The peripheral portions (40E) are exposed without being connected with the resistor element (3).

摘要:
A pressure sensor utilizing an extension type conductive elastomer that exhibits a decrease in its electrical resistance responsive to an extension applied thereto. Like sheets of the conductive elastomer 3 and an electrically insulative elastomer 2 are overlaid and sandwiched between supporting members within a housing 1. The housing and each supporting members are preferably cylindrical or ring shaped, which conductive elastomer has a pair of spaced electrodes 5,6 electrically connected thereto at its periphery. The periphery of the electrically insulative elastomer is squeezed continuously in a circle between the supporting members, while the periphery of the conductive elastomer is squeezed therebetween discontinuously in the sections between the electrodes. When a pressure is applied to the contacting elastomers, they will be convexedly deformed both experiencing an extension in their portions not being squeezed together. The applied pressure can be sensed as a change in electrical resistance across the electrodes.
