摘要： A method includes receiving distance measurements from at least one scanning head that moves back and forth across at least one surface of a web of material on a frame. The distance measurements identify measured distances to the web. The method also includes controlling one or more actuators in order to move at least a portion of the frame to alter a position of the at least one scanning head relative to the web. The one or more actuators could be controlled so that the at least one scanning head maintains a substantially fixed offset from the web as the at least one scanning head moves back and forth. The one or more actuators could also be controlled so that the web maintains a substantially fixed position between multiple scanning heads as the scanning heads move back and forth.

摘要： A pressure sensor includes a housing with a cavity. The cavity includes a fill fluid and a compensation material. The fill fluid conveys a pressure from a process fluid through a diaphragm to a sensor. The compensation material reduces a difference of thermal expansions between the cavity and the fill fluid.

摘要： An apparatus includes a cable track configured to be coupled to a moveable object and to be pushed and pulled by the movable object without buckling. The cable track is configured to transport at least one signal or material to or from the moveable object. The cable track has a fluid compartment defined between walls of the cable track. The walls of the cable track are configured to be separated when fluid is inserted into the fluid compartment and to approach one another in a bent portion of the cable track. The cable track may further include a web coupled to the walls, where the web is configured to limit the separation of the walls.

摘要： An apparatus includes a sensor body and a sensor configured to measure pressure. The apparatus also includes at least one pressure input in or on the sensor body, where the at least one pressure input is configured to provide at least one input pressure to the sensor. The apparatus further includes multiple fluid passages configured to convey the at least one input pressure from the at least one pressure input to the sensor using a fill fluid. The multiple fluid passages are configured to both (i) transport the fill fluid and (ii) absorb thermal energy in a flame created by the sensor before the flame exits the sensor body. The fluid passages can include long and narrow straight passages, long and narrow curved or helical passages, and turns or bends. The fluid passages can have small cross-sections relative to their lengths.

摘要： An apparatus includes a sensor body and a sensor configured to measure differential pressure. The apparatus also includes first and second coplanar pressure inputs in or on the sensor body, where the pressure inputs are configured to provide multiple input pressures to the sensor. Each pressure input includes a barrier diaphragm configured to move in response to pressure and an overload diaphragm configured to limit movement of the barrier diaphragm. First and second fill fluid may be configured to convey the pressures from the barrier diaphragms of the pressure inputs to the sensor as first and second input pressures. Passages may be configured to transport the fill fluid between (i) gaps between the barrier diaphragms and the overload diaphragms of the pressure inputs and (ii) the sensor and gaps between the overload diaphragms and the sensor body.
