electrofieldmeter Static Meter I

Product catalog summary

Introduction
Electrostatic charges are common in environments where highly insulating materials, such as plastics, are used. While theoretical evaluation of field patterns is possible, practical applications require knowledge of charge levels and locations within machinery or facilities. Specific devices are necessary to measure these charges effectively.

Measurement Principle
The measurement of electrostatic charges is based on the fieldmill influence principle. This involves influenced charges generating an alternating current proportional to the electrical field strength. A selective amplifier converts this into field strength or electrical potential without withdrawing energy from the field over time.

Static Meter I Overview
The Static Meter I is a newly developed, handheld field strength meter with a digital display for measuring electrostatic charges in volts. It combines ease of use with precise measurement capabilities.

Applications and Features

Precautionary use in manufacturing processes where electrostatic charges may occur.
Not approved for hazardous locations.
Variable measuring distance for optimal results based on charge degree and object surface condition.
Hold function to store measured values on the display.
Automatic conversion of field strength to equivalent charge in volts.
Supplied with two 26 mm spacers to ensure correct measurement distance.

Mode of Operation
The device converts the electric field of an electrostatic charge into a measuring alternating current through cyclical covering of sensor plates. The display shows tension proportional to the field's intensity and polarity. This method offers high sensitivity and accuracy.
