Start

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.

voltages of up to 10 kV on HAUG power packs .

This meter is equipped with an additional high-voltage socket

for connection to an ionizing unit. Thus the power pack and

of perforations

Applications

Mode of operation

Directions for installation

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.

The electric field of the electrostatic charge is converted into ameasuring alternating current through the cyclical covering ofthe sensor plates. The display shows a tension proportional tothe intensity and polarity of the field to be measured.Field strength meters that are working according to this priciplehave a high measuring sensitivity and allow very accuratemeasuring.

Field intensity meter Statometer III

The HAUG field intensity meter is a consistent

further development of the previous field intensity meter

Statometer II. It is intended for the measurement of electrostatic

and slow alternating fields.

With its new, patented measuring process, electric fields from

approx. 0.2 kV/m and low-frequency alternating fields up to

approx. 20 Hz can be measured. Due to the use of high-grade,

wear-free components, the can also be used in

continuous operation.

Special properties and benefits

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.

Applications

The HAUG can be used for the measurement of

electric fields or electrostatic charges both in the laboratory

and in production machinery.
