Owing to the continuous usage of centrifugal pump machines (CPM), health-monitoring systems are important for improving the hydraulic machine industry. While operating the CPM, supervision is carried out by either the operator or the online health-monitoring system. The Health Monitoring System (HMS) helps to understand the conditions of the pump and maintenance prospectus. For breakdown and accidents in the CPM industry, the prime reasons are impeller failure, bearing failure, cavitation, and shaft misalignment; therefore, it is necessary to supervise the parameters to provide a better life to the plant and enhance its efficiency using Data Acquisition (DAQ). The independent features and dependent features are selected and experimentally investigated to examine the characteristics of the CPM plant. The feature selection and extraction process should be compatible with the DAQ system which will help to reduce the curse of data biases and data preparation. Based on that three different DAQ systems based on Arduino, Raspberry Pi, and Dewsoft FFT are used in the experiments and compared based on 5-Point summary, Standard Deviation, cost analysis, flexibility, and maintenance. This paper presents the various techniques and procedures for acquiring the data from CPM using all three DAQ systems and selecting one of them through a statistical approach.

Major hurdle for SOFC operation at lower temperature is it’s ion migration through electrolyte crystal lattice reduces as more energy required and lowered number of ion vacancies. In order, researchers from all over the world trying to develop SOFC which operates at lower temperature which let to erupt the electrolyte performance. Currently available electrolyte YSZ (Yttria Stabilized Zirconia) shows high efficiency above 1100 °C. Fluorite structure doped/codoped ceria electrolyte shows better ionic conductivity below the 1000 °C. In current study ceria co doped with the Sm+3 and Nd+3 having ionic radius close to host ceria through oxalate co precipitation route. Crystallite size and structure is observed through X-ray diffraction for purity of doping with nano crystallite size transpose from 13.21 to 22.21 nm. Furthermore, Energy dispersive X-ray spectroscopy (EDXS) validates maximum 0.2 Codoping achieved through oxalate rought. Moreover grain size and grain boundary compaction enhances with sintering electrolyte pellet at 1300˚C for 2 h observed under FE-SEM. AC and DC conductive properties are studied with diverse codoping percentage and it is analyzed through Electrochemical Impedance Spectroscopy (EIS). Ce with 0.1 codoping Sm+3 and Nd+3 respectively enhances ion migration with minimum activation energy and relaxation time in lattice site.
