20100175481 | APPARATUS FOR MEASURING MULTIPLE PRESSURES WITHIN DIFFERENT PRESSURE RANGES - There is disclosed apparatus for measuring multiple pressures within different pressure ranges. The apparatus contains multiple pressure sensors which are positioned on a housing, where each pressure sensor is adapted to measure pressure within a different pressure range. The housing has an input port which is constructed to communicate with different output ports, where the output ports communicate with each different pressure sensor utilized in a different pressure range. The input port has a stepped or keyed aperture which is adapted to receive different pressure adapters to assure that, for example, only a high pressure will be applied to the high pressure sensor during high pressure measurements. By selecting another adapter, a mid-range pressure and a high pressure will be applied to the pressure sensors during the measurement of a mid-range pressure. By receiving a different adapter, a low pressure will be applied to all the pressure sensors during low pressure measurement. In this manner, one is assured that the pressure sensors are operated without damage to the diaphragms during all pressure measurements. It is of course noted that while three pressure ranges are indicated, there can be more than three or at least two pressure ranges can be accommodated within the common housing. As indicated, the common housing has an input port which consists of contiguous varying diameter sections to enable the selective insertion of various adapter members as indicated where each adapter member can only be inserted within the input port to a desired position, where at that position, the pressure applied to the input port will be directed to the proper sensor. | 07-15-2010 |
20100257936 | Internally switched multiple range transducer - There is disclosed an internally switched multiple range transducer. The transducer employs a plurality of individual pressure sensors or Wheatstone bridges fabricated from semiconductor materials and utilizing piezoresistors. Each sensor is designed to accommodate accurately a given pressure range, therefore, each sensor is selected to provide an output when an applied pressure is within its accommodated range. As soon as the pressure exceeds the range, then another sensor is employed to produce an output. Each of the sensors, or each separate transducer, is coupled to a switch or other device to enable the selection of one of the plurality of sensors to operate within its given pressure range when the applied pressure is in that range. In this manner one obtains pressure measurements with a high degree of accuracy across a relatively large pressure range. | 10-14-2010 |

20130199302 | PRESSURE BELT COMPRISING REPLACEABLE SENSING ELEMENTS - A pressure belt comprising a flexible belt, and a flat pack assembly removably attached to the flexible belt, wherein each flat pack assembly comprises at least one sensing element. Further, each flat pack assembly also comprises a memory component associated with the sensing element thereon, wherein the memory component houses data specific to the corresponding sensing element. Unlike prior art structures, each flat pack assembly is individually removable. Therefore, if one sensing element malfunctions, it may be replaced by removing the flat pack assembly comprising the malfunctioning sensing element and swapping it out for a flat pack assembly comprising an operable sensing element. This is an improvement over the prior art as it eliminates the need for replacing and recalibrating the entire pressure belt when one sensing element malfunctions, which can be both time consuming and costly. | 08-08-2013 |
20130220029 | BUILDING BLOCK TRANSDUCER ASSEMBLY - A transducer assembly configured to accommodate a plurality of individually tunable sensing elements of various geometries and configurations by using a cap and an accompanying capillary tube. The configuration of the various embodiments described herein eliminate the header to flat plate welds of the prior art, and therefore better accommodates a plurality of sensing elements and corresponding header assemblies within one transducer assembly. | 08-29-2013 |
