HAUG Static Meter I Static Measuring Unit
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.
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 use of the Static Meter I can be precautionary measure in all manufacturing processes, where electrostatic charges may occur. However, this device is not approved for use in hazardous locations!
