For the realization of the device, constructed by us, a surface potential measuring sensor EFS-22D has been used, consisting of a measuring probe and an electronic converter for measuring voltages in the range from 0V to 900V at a distance between the sample and the surface of the probe within 1 – 3.5mm. The measuring probe is composed of an oscillating mechanism (of the type of a tonometer), with metal electrodes attached to it, which block the electric field. The movement of these electrodes is accomplished by means of a piezo-electric element. The chopper is tuning fork oscillator type shutter. The surface potential, measured by the probe of the sensor, is converted into analogue voltage, varying from 0 to 4.5V, which is then converted into a digital value by a 15-bit sigma-delta analogueto-digital converter, connected to a microcontroller. The data from the measurements are transmitted from the microcontroller to a personal computer through a Bluetooth module. User software has been developed, allowing for: recording the obtained values from the measurements; their visualization both in digital and analogue form; digital filtration of the noise from the sensor; and statistical analysis of the obtained data","PeriodicalId":374877,"journal":{"name":"2018 IEEE XXVII International Scientific Conference Electronics - ET","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133456666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
