Abstract

A Coriolis mass flowmeter in which common or even great forces for oscillation excitation can be guaranteed, and at the same time, with which the risk of flashover is reduced in explosion-proof surroundings is implemented in that the actuator assembly (4) has at least a first conductor (11) with windings (12) and at least a second conductor (13) with windings (14), the windings of the conductors being arranged parallel to one another. Also, the first conductor (11) and the second conductor (13) are insulated from one another at least in the area of their windings (12, 14) and the first conductor (11) and the second conductor (13) are connected in such a manner that the first conductor (11) and the second conductor (13) can be supplied with a current in the same manner in the operating state so that a common magnetic field is created.

Dependent claims

Coriolis mass flowmeter comprising:

at least one measuring tube and
at least one actuator assembly having at least one first conductor with windings and at least one adjusting element, and at least one second conductor with windings, wherein for increasing magnetic intensity while reducing susceptibility to flashover, the windings of the at least one second conductor being arranged parallel to the windings of the at least one first conductor, the at least one first conductor and the at least one second conductor being insulated from one another at least in an area of the windings and the at least one first conductor and the at least one second conductor being connected in such a manner that the at least one first conductor and the at least one second conductor are adapted to be supplied with a current in the same direction in an operating state so that partial magnetic fields of the conductors are structurally superimposed into one common magnetic field.
