Digital meter Static Meter I

electronicelectrostatic charge

The Static Meter I electrofieldmeter is a small hand-held field strength meter with digital display for measuring electrostatic charges in Volt. It perfectly combines easy operation with accurate measuring technique. The Static Meter I measures charges according to the fieldmill influence principle C: The influenced charges, caused by electrically field, generate an alternating current proportional to the electrical field strength. The selective amplifier converts this value into the corresponding field strength or electrical potential – without withdrawing energy from the electric field over the averaged time. Measuring electrostatic charges Electrostatic charges always occur where highly insulating materials, such as most plastics, are used. The resulting field patterns, such as A and B, are easy to be evaluated theoretically, but they are of minor interest to the practician. For the latter it is important to know the level of these electrostatic charges and the spot in the machine of facility where they occur. Therefore he should have specific devices at his disposal to measure these interfering charges. SPECIAL FEATURES AND ADVANTAGES Variable measuring distance: In order to obtain optimum results, the distance between test object and sensor head – depending on the degree of charge and the condition of the objects’s surface – can be selected incrementally. Hold function: The device is equipped with a Hold function to keep the measured value stored on the display. Display in Volt: The integrated micro-computer automatically converts the measured field strength into the equivalent charge in Volt.
