摘要： The invention relates to a density measuring device which is used to measure a density, ρ, of a flowable medium and comprises measuring-device electronics (ME) and a measuring transducer (MW) electrically connected to the measuring-device electronics. The measuring transducer comprises a measuring tube (10), a vibration exciter (41) for exciting and maintaining vibrations, and a vibration sensor (51) for sensing vibrations of the at least one measuring tube. The measuring device electronics are designed to adjust, by means of a vibration measurement signal (s
1 ) and an exciter signal (e
1 ), a driving force that causes useful vibrations, namely vibrations having a specified useful frequency, f
N , of the measuring tube, in such a way that a phase shift angle, φ
Ν , by which a velocity response, V
N , of the measuring tube is phase-shifted with respect to a useful force component, F
N , of the driving force is less than -20° and greater than -80° during a specified phase control interval, and/or the useful frequency has a frequency value that is more than 1.00001-times but less than 1.001-times a frequency value of an instantaneous resonance frequency of the measuring tube. Furthermore, the measuring device electronics are designed both to determine at least one frequency measured value, X
f , representing the useful frequency for said phase control interval on the basis of the vibration measurement signal (s
1 ) present during the phase control interval and to generate a density measured value, X
ρ , representing the density, ρ, by using the frequency measured value, X
f .

摘要： The invention relates to a transducer, in particular also for the use in a Coriolis mass-flow measuring device, comprising at least one measuring tube (10), which is at least temporarily vibrating during operation, for guiding flowing medium, and a sensor array (50) serving to detect vibrations of the measuring tube (10). The measuring tube extends between a first measuring tube end on the inlet side and a second measuring tube end on the outlet side, having a vibration length (L
10 ) and performing vibrations about a pivoting axis that is parallel or coincident to an virtual connecting axis which imaginarily connects the two ends of the measuring tube, for example in a bending vibration mode. The sensor array generates a first primary transducer signal representing vibrations of the measuring tube (10) by means of a first vibration sensor (51) disposed on the measuring tube (10), and generates a second primary transducer signal representing vibrations of the measuring tube (10) by means of a second vibration sensor (52) disposed on the measuring tube (10) at a distance from the first vibration sensor (51), wherein the length of an area extending between the first and second vibration sensor of the first measuring tube (10) defines a measuring length (L
50 ) of the transducer. In a transducer according to the invention, the vibration sensors of the sensor array are placed in the transducer in such a way that a sensitivity (S
IST ) of the transducer, with respect to a theoretical sensitivity at a measuring length (L
10 = L
50 ) that maximally corresponds to the vibration length, as well as a signal amplitude (A
IST ) of the primary signals, effectively obtained during operation and with respect to a theoretically maximal possible signal amplitude (A
MAX ) at the location of a maximal vibration amplitude, meet the condition (I).

摘要： The invention relates to a measuring system which comprises a vibration transducer through which, when operated, a medium flows, for producing vibration signals that depend on a viscosity of the flowing medium and/or on a Reynolds number of the flowing medium, and to an electronic transducer system which is electrically coupled to the transducer for controlling the transducer and for evaluating vibration signals supplied by the transducer. The transducer comprises a splitter (20
1 ) on the inlet side which has four interspaced flow openings (20
1A , 20
1B , 20
1C , 20
1D ), a splitter (20
2 ) on the outlet side which has four interspaced flow openings (20
2A , 20
2B , 20
2C , 20
2D ), four straight measuring tubes (18
1 , 18
2 , 18
3 , 18
4 ) for guiding the flowing medium which tubes are connected to the splitters (20
1 , 20
2 ) to give a system of tubes with fluidically parallel flow paths, and an electro-mechanical exciter arrangement (4) for exciting and maintaining mechanical vibrations of the measuring tubes (18
1 , 18
2 ). The measuring tube end on the inlet side of each of the four measuring tubes leads to a flow opening (20
1A ) of the splitter (20
1 ) on the inlet side and the second measuring tube on the outlet side leads to a flow opening (20
2A ) of the splitter (20
2 ) on the outlet end, a first measuring tube end on the inlet side of a third measuring tube (18
3 ) leads to a third flow opening (20
1C ) of the first splitter (20
1 ) and a second measuring tube end on the outlet side leads to a third flow opening (20
2C ) of the second splitter (20
2 ) and a first measuring tube end on the inlet side of a fourth measuring tube (18
4 ) leads to a fourth flow opening (20
1D ) of the first splitter (20
1 ) and a second measuring tube end on the outlet side leads to a fourth flow opening (20
2D ) of the second splitter (20
2 ). The electronic transducer system feeds electrical excitation power to the exciter arrangement by means of an electrical driver signal supplied to the exciter arrangement, while the exciter arrangement converts electrical excitation power, at least proportionally, to torsional vibrations of the first measuring tube (18
1 ) and to torsional vibrations of the second measuring tube (18
2 ) which are diametrically opposed to the torsional vibrations of the first measuring tube (18
1 ), and to torsional vibrations of the third measuring tube (18
3 ) and to torsional vibrations of the fourth measuring tube (18
4 ) which are diametrically opposed to the torsional vibrations of the third measuring tube (18
3 ).

摘要： The invention relates to a measuring transducer comprising a housing and an inner part arranged in the housing. The inner part comprises at least one curved measuring tube (10) which vibrates at least intermittently during operation and is used to guide the medium, and a counter-oscillator (20) which is fixed to the measuring tube (10) on the inlet side in such a way as to form a coupling region (11#), and on the outlet side in such a way as to form a coupling region (12#). The inner part is held in a vibrating manner in the converter housing at least by means of two connection tubular pieces (11, 12) which enable the measuring tube (10) to communicate with the tubular line during operation, and which are oriented in relation to each other and to an imaginary longitudinal axis (L) of the measuring transducer, such that the inner part can oscillate about the longitudinal axis (L) during operation. Furthermore, the measuring tube (10) and counter-oscillator (20) are embodied and oriented in relation to each other in such a way that both a centre of mass M10 of the measuring tube, located at a certain distance from the imaginary longitudinal axis (L), and a centre of mass M20 of the counter-oscillator (20), located at a certain distance from the imaginary longitudinal axis, lie in a common region of the measuring transducer which is defined by the imaginary longitudinal axis (L) and the measuring tube (10), and in such a way that the centre of mass M10 of the measuring tube (10) is located further away from the longitudinal axis (L) than the centre of mass M20 of the counter-oscillator (20).
