Abstract: An electromagnetic flowmeter includes a measurement tube having a mounting tube liner and a control module installed in an outer side of the measurement tube. A magnetic field module is installed in an outer side being orthogonal to a shaft of the measurement tube without contacting the working fluid. An electrode structure is disposed on an outer surface of the measurement tube and partially extended in the mounting tube liner to contact the working fluid. The actuator element is electrically connected with the control module and connected with the electrode structure. The actuator element is driven by an external force to drive the electrode structure toward the mounting tube liner inside and being orthogonal to the mounting tube liner for compensating the wear of the electrode structure so as to obtain a correct measurement result and increase the service life.

Abstract: A cable-base sensor can detect a material level and temperatures of a material stored in a silo. The cable-base sensor comprises an electronic box, a cable, a stopper, and a signal processing module. The electronic box comprises a base and a space for containing the signal processing module, and a hole is formed through a bottom of the electronic box. The base is mounted in the bottom, and a tapered hole is formed through the base. A first end of the cable extents into the tapered hole and the hole, and spreads to form a cable bud. The stopper is a tapered block and pressed into the tapered hole for enforcing the cable bud to be sandwiched between the stopper and the base. The cable bud strengthens a connection between the electronic box and the cable for preventing damages from solid materials.
