| Zusammenfassung | This paper will show whether the measurement of the electric field strength is suitable as a criterion for the measurement of the electrostatic charge, as well as for the assessment of its flammability. Electrostatic charge is a significant and most difficult to control ignition source in potentially explosive atmospheres. The measurement of the electric field strength by means of electric field meters can be carried out without contact or disturbing the object under investigation - the charging of the material - and without causing a discharge. If the latter can be guaranteed in any application, the process would be safe for use in potentially explosive atmospheres. For the metrological characterization of the non-contact measurement of electrostatic charge, a test setup was developed, as a first step, which represents the parameters to be examined (e. g. real surface geometries, distances dependence). Initial results of the preliminary investigations showed that the measurement accuracy with regard to distance dependence could be determined in homogeneous E-field configurations. In addition to the metrological characterization of the electric field meter measurement, theoretical considerations are necessary. For this purpose a simulation model was built, using COMSOL Multiphysics, which represents the experimental setup of the developed measurement methodology for homogeneous electric field configurations. The simulation model was validated on the basis of the first experimental test results. With the help of the simulation model, a passive investigation method (without electrostatic charge or voltage source) was developed for the characterization of the electrical field meter. The metrological and simulation-based test results serve as the basis for establishing a calibration procedure for electric field meter, a measurement procedure for the evaluation of electrostatic charging and for assessing their ignition capability. |
