The Static Meter electrofiel meter 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 measures charges according to the
field 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.
- 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 objectss 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 microcomputer automatically converts the measured field strength into the equivalent charge in Volt.
of Operation :
Field pattern of an uniformly charged film A and of a uniformly charged film above the earthed/grounded metal plate B: The electric field of the electrostatic charge is converted into a measuring alternating current through the cyclical covering of the sensor plates. The display shows a tension proportional to the intensity and polarity of the field to be measured.
Field strength meters are working according to this principle have a high measuring sensitivity and allow very accurate measuring
Two 26 mm long spaces are supplied together with the
device. These ensure that the distance of measurement
is always correct (= 2 cm).
The LG is an indispensable production aid for film processing,
electronic manufacture, and precision mechanics. This
device has also proven to be very reliable and efficient
for the manufacture of measuring devices and control
gears, for PCB assembly as well as for screen and
pad printing and other printing procedures
