1. Answer: a. Acting as a secondary transducer, LVDT can be used as a device to measure force, weight & pressure etc. 14. The dynamic range of the transducer is the ratio among the high amplitude signal as well as the least amplitude signal so that the transducer can efficiently translate. Zero offset A real sensor will deviate from the idealised linear model. The resonant frequency (or natural frequency) is the frequency at which the monitoring system itself resonates and amplifies the signal. Definition of LVDT. ANSWER: B. Varies over a wide range, remains constant « Previous; Next » Post your comment. Time lag: C. Dynamic error: D. Reproducibility : 2. 11. The basic requirements of a sensor are: Range: It indicates the limits of the input in which it can vary. Go To Download Page Close.
