Electrostatic Charges occur on the surface of non-conductive material. These charges are usually created by a separation process. For example, a film running across idler rolls along a web will have a tendency to develop an electrostatic surface charge at the point of separation. Depending on the Material, these static charges can be positive or negative.
These Charges can be measured by an electrostatic field strength meter. There are different methods of determining the intensity of these surface charges. They allow for either a constant monitoring of the electrostatic charges or measuring the static at a specific spot on the material.

The high-voltage test unit Powercheck is a performance testing
unit for HAUG power packs.
To test power packs, the black measuring probe with the spring
pin must be inserted into the high-voltage socket of the power
pack (photos 3, 4).
After pressing the red push button, the LED will illuminate green
if the unit is functioning correctly. In case of malfunction, the
LED will illuminate red.
Combicheck: Performance testing of
power packs and ionizing units
The high-voltag test unit is a performance testing
unit for HAUG power packs and HAUG ionizing units.
A selector switch allows the units to be adjusted for the testing
of power packs or ionizing units. In position "Testing of power
packs", the front LED will illuminate, while in position "Testing of
ionizing units" the rear LED will illuminate. To test power packs,
the black measuring probe with the spring pin must be inserted
into the high-voltage socket of the power pack (photos 3, 4).
To test ionizing units, the probe must be held close to the

The perforation counter is mainly applied in themanufacturing of plastic bags. The contactless detection ofperforations allows the number of bags/batches to bedetermined and indicates when the material rolls need to bechanged.
Sparks are generated at the point of the perforation of the filmby means of a high-voltage electrode (counting electrode) anda suitable earthed/grounded counter-electrode. These sparksare interpreted and counted by the logic circuit integrated in the
perforation counter and indicated visually on the displaythrough a light-emitting diode. The counting pulses transmittedby an opto-coupler can be interpreted by an external counterand may be used for activating other machine functions (suchas the control of reversing winding machines and cuttingmachines).
The counting electrode must be mounted above the materialweb at a distance of approx. 10 to 20 mm and centered overthe perforations to ensure the perfect functioning of the .An earthed/grounded counter-electrode below the material web(e.g. earthed metal drum) must be in physical contact with thefoil opposite the counting electrode.

Special features and advantagesThe perforation counter offers the possibility to captureup to 900 counting pulses per minute. This corresponds to acounting rate of 15 counting pulses per second (15 Hz).The duration of the counting impulses is adjustable from5 to 1000 ms. This helps to suppress subsequent spark-oversthat may be triggered by "holes" in the film and should not becounted.The high voltage applied to the counting electrode is infinitelyadjustable from 2.4 up to 17 kV .The external release of the output voltage can be activatedthrough a voltage-free contact, so that high voltage is appliedto the counting electrode, for instance when the material webis moving.

Properties of the evaluation software
Due to the geometry of the measuring head, very low field
intensities can be measured. The calibrated measuring distance
of the measuring head to the measured surface is 30 mm. The
measuring head is connected to the display unit via a coiled
cable. The has three measuring ranges which
are switched over automatically during measurement. No
manual switchover is therefore required.
The field intensity meter can be operated both from the mains
and with commercially available NiMH rechargeable batteries.
An integrated automatic switch-off function protects the
batteries from exhaustive discharge.
Using the supplied optical connection cable, the
can be connected to a PC's serial port in a floating connection.
The supplied software allows the large display of the current
measuring value or the performance of short-term and long-
term measurements over several days.
The measured values can be displayed graphically and
exported, e.g. for further processing in measuring and
analytical programs. Variable zooms are possible.
The measured data can be saved to hard disk and archived.
