    摘要: A pressure sensor (40) useful as a vacuum manometer. A reference pressure cavity (50) of the sensor is evacuated through an evacuation opening (72) located behind a plate portion (54) of the sensor electrode (52) having a non-planar surface for supporting the diaphragm (44) during an overpressure event. The electrode is hermetically sealed to the body (42) of the sensor by a brazed joint with a ceramic seal member (60) disposed there between. The brazed joint may include a layer of buffer material (79) which provides a degree of malleability to the joint to avoid cracking of the ceramic seal member. The brazed ceramic/metal joint permits the selection of materials such that differential thermal expansion effects can be passively minimized. The electrode is connected to the sensor circuitry (84) by a wire having a spring section (53), thereby providing a stress free interconnection.

    摘要: A capacitive sensor (10) producing an output signal (VOUT) that is insensitive to stray capacitance (CS) caused by environmental and aging conditions. The sensor includes a sensing electrode (11) that exhibits a total capacitance that is responsive to both the measured process variable and to stray capacitance (CT=CA+CS). The sensor also includes a reference electrode (19) that exhibits a stray capacitance (CS′) essentially the same as that of the sensing electrode, but that is insensitive to the process variable. Balancing circuitry (29) provides an output signal that is responsive to the measured process variable and insensitive to the stray capacitance (VOUT=CT−CS′). The reference electrode is manufactured of the same materials and dimensions as the sensing electrode and may be mounted in the sensor body proximate the sensing electrode.

    摘要: A surface mounted instrument (20) that is easily installed to seal (110, 120) against a mounting surface (150) in spite of imprecise installation of a standard rough-in box (145) or irregularities in the surface. A cover plate (60) overlays the installed instrument housing (10) without the use of outwardly visible mechanical connectors by use of a pawl (65) that engages the housing. An oversized display (50) is mounted for easy replacement on a moveable display module (45) for unobstructed access to the interior (35) of the housing. Subsurface channels (90) formed in the housing are used to deliver a working fluid from a measured location to a sensor (85) inside the housing.

    摘要: An environmental condition monitor (200) configured for simple upgrade from analog signal output to any of a plurality of digital communication protocols. A display board (202) includes the analog signal acquisition and processing elements of the device and also includes a pre-positioned but initially inoperative digital communication output connector (214). A connector board (204) associated with the display board includes a connector (212) to which any one of a plurality of digital communication boards (210) may be selectively connected, depending upon which of a plurality of digital communication protocols is desired. Selective connection of a digital communication board completes a circuit whereby an analog output signal is converted to the desired digital output format and is then communicated back to the now-activated digital communication output connector (214).
