What is an electrostatic voltmeter?

Electrostatic voltmeter measures the surface voltage of any particular material without over -current transmission. In other words, this tool is more precisely measuring the static charge generated by the material surface without contributing to the excessive charge to the results in the process. When measuring the material voltage, the current generated between the device and the material surface creates a natural charge that can distort the results of the actual voltage of the material. The electrostatic voltmeter is therefore necessary to prevent inaccurate measurements and results.

Although the electrostatic voltmeter may be required to touch the surface to measure, the most demanded electrostatic voltmeters require no contact between the probe and the surface of the material to ensure clean results. In fact, the probe is located about 0.04-0.20 inches (1-5 mm) from the surface-to-be, but at all touch the material. In addition, many of these types of voltmeters are equipped with the ability to force an electric field between the probe and the surface. This is possible because the voltmeter will increase tothe five instrument probe until the voltage of the surface in question corresponds. If both voltages are the same, the voltmeter is more precisely able to measure the surface voltage and often achieve accuracy within 0.05-0.1 percent of the full scale.

There are a number of significant advantages of using the electrostatic voltmeter except for the high level of measurement accuracy. Such voltmeters facilitate the measurement of the voltage of the movable surface. Noing the electrostatic field between the probe and the surface allows more freedom to change the gap between the probe and the surface of the surface that is measured at once.

Data collection with an electrostatic voltmeter also minimizes the chance between the probe and the surface surface. The ARC-Over concerns the resulting charge formed from the interaction between the high-voltage surface and the instrumental probe. Electrostatic cancellation is eliminated by Arc-over, allowing more stable direct current (DC). More stable DC electricity againIt leads to a remarkable accuracy of the electrostatic voltmeter over its more common counterpart, electrostatic terrain. Field meters measure the total voltage of the material and not just the surface voltage of the material, important in determining the electrostatic potential between the material surface and the industrial machine.

electrostatic voltmeters are usually used in the industrial sector. They are used for a wide range of applications specific to enterprises in this industry. The use may include measuring the surface tension of industrial materials such as rubber, plastics and polymers; evaluation of the effects of radiation; And analysis of the properties of photoreceptors.
