摘要： A high-pressure sensor includes a deformation member (1) and connection piece (2) that is joined to the deformation member (1) by a welded seal. The deformation member has a truncated-cone-shaped circumferential segment (8), via which a welding current can be supplied, in order to weld the two pieces to each other in response to a simultaneous pressing together of deformation member (1) and pressure connection piece (2). A welding electrode (16) that is suited for this purpose is configured in a cup shape having a spring-loaded nonconductive insert (17) that can be axially displaced in the interior of the cup.

摘要： A pressure gauge having pressure range indicating needles allows the positions of the pressure range indicating needles to be moved without detaching the cover from the pressure gauge body. The pressure gauge has an internal device, a pointer, a pressure scale plate and pressure range indicating needles, which are provided in the pressure gauge body. A window hole is formed in the cover. A transparent cover plate is fitted in the window hole of the cover in such a manner as to be capable of being opened and closed. With the cover left attached to the pressure gauge body, the tip of a screwdriver or the like can be brought into contact with the pressure range indicating needles through the window hole when the transparent cover plate is open, to move the pressure range indicating needles.

摘要： A process parameter associated with a material contained in a vibrating structure is estimated. A plurality of motion signals representing motion at a plurality of locations of the vibrating structure are received. The received plurality of motion signals are force filtered with a force filter to produce a force-filtered motion signal that discriminates motion attributable to a force of interest among a plurality of forces acting on the vibrating structure. A process parameter associated with the material contained in the vibrating structure is estimated from the force filtered motion signal. Preferably, a plurality of motion signal values is generated from the received plurality of motion signals, and force filtering includes the step of applying a force filter matrix to the plurality of motion signal values to produce a force filtered motion signal value. A process parameter, such as mass flow, density or the like, is then estimated from the force filtered motion signal value. According to an aspect of the present invention, the force filter matrix represents a product of a frequency response function matrix for the vibrating structure, a force selectivity matrix and an inverse of the frequency response function matrix. Methods for estimating structural motion, along with related apparatus and computer program products, are also discussed.
