Laboratory tests of the detector prototype are performed for measurement of viscosity of base synthetic and mineral oils. It was found that measurement accuracy was better when damping factor was estimated in comparison with accuracy of frequency of damped oscillations. Thus the oil viscosity was calibrated as a function of number of pulses of the damped oscillations of magnetoelastic ribbon. Result generally showed that developed detector is promising for in line oil viscosity measurement in wide viscosity range from 10 cSt up to 600 cSt, while the viscosity measurement was relatively instable when the viscosity of test oil was over 400 cSt. Korean 한국트라이볼로지학회 자기탄성체 리본의 공진을 이용한 인-라인 오일 점도센서 In-line Oil Viscosity Sensor Implementing An Elastomagnetic Ribbon Resonance Article 2 한국트라이볼로지학회지, v.26, no.2, pp.97 - 104 한국트라이볼로지학회지 26 2 97 104 N kci ART001468865 오일 동점도 음향점도 자기탄성체 리본 공진 oil kinematic viscosity acoustic viscosity eleastomagnetic ribbon resonance
