General information of the principle of electrostatics
Electrostatic discharging is a today problem on many working places with the use of modern
micro-electronics as e.g. Microchips and their sensibility against it.
There is also a very strong danger for industrial branches as e.g. Telecommunication-, Plastics-, and
manufactures of explosives.
The loss in manufacturing time as well as high financial damage and the affection of the
health of persons may be caused by ESD (electrostatic dischargement).
It is possible that electrical charges of over 10.000 V can build up on human clothes,
materials, and equipment.
Damage on electronic components may already occur with a charge of less as 100 V and
charges of 3.000 V are able to flash and may be the result of explosion in hazardous areas.
What is the result of electrostatic charge
Trough friction and separation of different materials the so called - Tribo Electricity - (it stays for the
Greek word tribeia which means friction) will be generated.
The reason is a transfer of electrons between the two materials.
Since the charge of electrons is negative the material depleting electrons has a positive charge,
compare the material enhances electrons shows a negative charge.
There are different ways to prevent or divert electrical charges. However, to find a useful and
effective way, first the source and the charge of the electrostatic field should be located and
polarity and strength measured.
To do so as well as check any chosen steps against electrostatic charge or to control desire
charge our Electro-Field meter is recommended.
Description
The modulator-system with the complete electronic is integrated in a metal tube-housing.
The metal–tube is connected to ground.
The influenz–measure-electrode is in shape of a star. In front of this electrode rotates a
ground-connected modulation-vane-wheel with the same shape. These parts are hard-gold-
plated to prevent galvanic distortions. An influenz-electrode covers the ring-electrode-system
for mechanical protection.
At the back-side there is a balanced-potentiometer to adjust the offset.
The signal-output to the PC etc. occurs about a Mini - USB – Interface connector.
The USB also powers the unit – Interface.
