Electrostatic Field Meter serves and likewise versatile tools for resolving static concerns. Fixed charging problems are challenging to detect since the source of the billing often goes to a different location than the observed promotes. An Electrostatic Field Meter can determine locations where the fixed expense is high. It can show the polarity of the cost, which helps determine the resource of the charging. A field meter likewise can offer a quantitative estimate for the amount of fixed charge. Measuring cost and tracking the level through a procedure is an outstanding way to find the source of fixed charging.
When using an Electrostatic Field Meter to identify a static charging concern or when selecting a field meter for a certain application, three efficiency actions are very important: variety, spatial resolution, in addition to action time.
While the electrical field officially is evaluated in volts per meter, one volt per meter is an incredibly small field. Electric field meter frequently show fields in kilovolts per centimeter (kV/cm), kilovolts per inch (kV/in.), and also a couple of variations provide the determined field simply in volts. The range, either centimeter or inch, is indicated.
The electric field (E) is limited by the breakdown strength of air. At air pressure, E remains in the series of 0 to ± 30 kV/cm or 0 to ± 76 kV/in. For practical work, an affordable upper limit is 20 kV/cm or 50 kV/in. Your field meter must have a resolution of at the very least 1 kV/cm or 2.5 kV/in. so you can find a 1 µC/ m2 modification responsible density on your motion picture, which is practically considerable.
The electrical field (E) is limited by the breakdown strength of air. So at atmospheric pressure, E stays in the series of 0 to ± 30 kV/cm or 0 to ± 76 kV/in. For functional work, an economical ceiling is 20 kV/cm or 50 kV/in. Your field meter ought to have a resolution of at the very least 1 kV/cm or 2.5 kV/in. You can find a 1 µC/ m2 modification responsible density on your film, which is virtually considerable.
An Electrostatic Field Meter reacts to costs where the noticing unit is the closest metal product. The electrical field meter reading EMIDDLE is one of the most trustworthy as well as safe given that it reacts to costs on the film in a well-balanced region that is halfway in between rollers. Evaluating ENEAR likewise replies to charges in a region that is approximately midway between rollers. The measurement geometry is not balanced, and reading ENEAR will definitely be a lot more variable and much less trusted than checking out EMIDDLE. Checking out EROLLER will definitely be no due to the reality that the roller is the closest steel challenge to the motion picture.
The reaction time of an electrical field meter establishes the size of the fee variant that can be identified. Preferably, the action time (TRESPONSE) should be rapidly adequate to discover charge spots with the same measurement as the spatial resolution (RESOLUTION).
