    摘要: An environmental sensor apparatus and method of making same is disclosed in which an environmentally sensitive silicon die is sandwiched between an elastomeric media seal and a conductive elastomeric pad contained within a housing. The conductive elastomeric pad contacts a printed circuit board (PCB) which leads from the housing. The die, elastomers and PCB are secured by a press fit plug which contacts the PCB and is heat staked to the housing to provide a substantially flush hermetic seal.

    摘要: A sensor package having a force sensing element and a housing. The force sensing element has an element surface, a well, a first and second shelves within the well. The housing has a housing surface. The first and second shelves of the housing are arranged to support the force sensing element so that the element surface and the housing surface are substantially coplanar and so that the element surface of the force sensing element directly senses a force without need of an actuator.

    摘要: A flow sensor package with a housing, a pressure sensing element, a restriction, and an elastomeric seal. The housing has a base, a cover, an inlet port, an outlet port, and first and second channels. The first and second channels are in parallel between the inlet port and the outlet port. The pressure sensing element is in the first channel and the restriction is the second channel. The elastomeric seal engages the pressure sensing element to prevent flow of a fluid, which may be a liquid, through the first channel. The elastomeric seal has a conductive path from the pressure sensing element to a lead, which extends outside the housing.

    摘要: A pressure sensor is provided with an insert member that reduces the dead space of a fluid conduit used to provide fluid communication between a pressure sensitive component and a cavity within which a volume is contained. The insert member is provided with a channel formed in its outer surface so that continued fluid communication can be maintained between the fluid whose pressure is to be monitored and a pressure sensitive component disposed within the structure of the pressure sensor. The use of the insert member significantly facilitates the manufacture of the pressure sensor and reduces the need to utilize pins of excessively small cross sectional area during the molding process.

    摘要: A force sensor is provided with a two piece actuation system. A first actuator is disposed in contact with the pressure sensitive component and a second actuator is disposed in contact with the first actuator. When an external force is exerted against a distal end of the second actuator, for force is transmitted through the second actuator to the first actuator. The force is then transmitted through the first actuator to the pressure sensitive component. By using a two piece actuation system, the first actuator can be maintained at a constant location in contact with a position on the pressure sensitive component. This position will not vary even when the second actuator is moved or tilted. An elastomeric plate can be used to retain the first actuator in a constant position relative to the pressure sensitive component.

    摘要: The present invention relates generally to a pressure sensor and, more specifically, to a pressure equalization structure that balances the forces on the pressure sensitive component in order to reduce the stress that could otherwise be imposed on its piezoresistors. The pressure sensor provides a housing in which a cavity is formed. Within the cavity, a pressure sensitive component is disposed between a first seal and a second seal in order to expose a first surface of the pressure sensitive component to a first conduit and a second surface of the pressure sensitive component to a second conduit. The pressure surrounding the pressure sensitive structure is generally equalized to one of the first and second conduits by providing a bypass conduit connected therebetween.

    摘要: A pressure sensor die is provided with a flexible membrane and a plunger which combine to amplify a low pressure signal while also providing media isolation between a fluid being measured and the internal components of a pressure sensor. One embodiment of the pressure sensor disposes an end of the plunger in direct contact with a pressure sensor die while another embodiment disposes an elastomeric diaphragm between the plunger and the pressure sensor die. This second embodiment creates a chamber between the plunger and the pressure sensor die in which a fluid is captured by movement of the plunger. The captured fluid is decreased in volume by movement of the plunger and the resulting increase in pressure in transmitted to a pressure sensitive portion of a pressure sensor die. The device is particularly useful in conjunction with applications where media isolation is required between the fluid being measured and the components of the pressure sensor, such as kidney dialysis machines. It is also particularly useful where electrical isolation is required to prevent any possible shock hazard that could otherwise result from fluid communication between the fluid being measured and the electrically conductive portions of the pressure sensor. One embodiment of the pressure sensor comprises a means for preloading a pressure sensor die at atmospheric pressure in order to permit the device to measure both positive and negative pressures within the first chamber.
