  • Publication number: 20220307889
    Abstract: A monoblock sensor body of a load cell based on an electromagnetic force compensation mechanism has a Roberval mechanism. Mounting portions mount the fixed column to a housing side of a weighing module, and mount a load receiving member to the movable column. At least one of the mounting portions has at least one mounting hole that extends predominantly orthogonal to the load direction. One of the flexure point sections is closest to the mounting hole. A cavity associated with at least one of the mounting portions reduces an available solid angle for straight propagation paths that run from the inner thread to one or more of: the closest flexure point section, the coupling and the closest fulcrum. A material boundary of the body closes the cavity over at least a bridging width versus the height-side end of the body corresponding to the closest flexure point section.

  • Publication number: 20220268729
    Abstract: Provided is a method for monitoring a change of ion strength in a sample solution by a closed-loop device that provides continuous cycling of electrochemical pH modulation between pre-defined pH values. In particular, the change of ion strength may be induced by a chemical reaction and may ultimately alter the electrical control parameters of the closed-loop device. By measuring such electrical control parameters, the degree and progress of the underlying chemical reaction may be monitored.
