Abstract
A Coriolis mass flowmeter (1) having at least one sensor arrangement (2), at least one transducer (3) and at least one housing (4), wherein the sensor arrangement (2) has at least one measuring tube (5) that can be excited to oscillation, at least one oscillation generator (6) and at least one oscillation sensor (7), wherein the transducer (3) at least in part has evaluation and power electronics for controlling and measurement evaluation of the sensor arrangement, wherein the sensor arrangement (2) and the transducer (3) are arranged adjacent to one another in a common volume defined by the housing (4). A Coriolis mass flowmeter of the described type, in which the physical interaction between the sensor arrangement and transducer is reduced, is realized by the provision of a thermal barrier (8) arranged at least in a space between the sensor arrangement (2) and the transducer (3).
