Question No 1 (25 marks) A platform of weighing system is resting on Four (04) Springs. An LVDT is installed below the platform to sense the downward displacement when a load is placed on the platform. In absence of any load on the platform, the LVDT is at its mean position (output= O). Answer the following: Note-1: Specifications of LVDT and Spring given below: Note-2: loal is equally distributed on all spring. Note-3: Imm-00393701 inch. a) Evaluate the sensitivity of LVDT. b) A load of 1200 Lbs is placed on the platform. i. Determine the displacement of the platform in inch & mm after evaluating the compression of each Spring. ik Evaluate the output of LVDT. c) What is the error in the output of the LVDT sensor in part-b(ii)?
