What Is an Electrostatic Instrument?
A electrostatic instrument is a device that measures static electricity generated by a charged object. The instrument is equipped with a non-contact sensor, and measurement can be made simply by pointing the sensor at the object.
Officially, an instrument for measuring static electricity is called a surface potentiometer or electrostatic potential measuring instrument.
The unit of measurement is expressed as V (volts). The higher the voltage, the greater the charge and the higher the static charge.
The form of the device differs depending on the application, such as monitoring static electricity on a production line.
Uses of Electrostatic Instruments
Electrostatic instruments are mainly used to monitor static electricity at manufacturing sites. Static monitoring is necessary as a countermeasure for several possible problems caused by static electricity.
1. Foreign Object Adhesion:
Trouble occurs when charged foreign objects (dust, etc.) adhere to charged products.
2. Electrostatic Destruction (ESD Destruction):
Electronic components such as integrated circuits are often vulnerable to weak electricity and may be destroyed by electrostatic discharge.
3. Malfunction:
Equipment (electronic balances, weight checkers, metal detectors, etc.) that operate on minute currents and voltages are said to be affected by electromagnetic noise originating from static electricity.
4. Discharge to the Human Body:
Discharge of charged electricity not only causes pain and discomfort to the human body, but can also cause equipment trouble and ignition.
Principle of Electrostatic Instruments
When static electricity is charged, it creates an electric field. The sensor of electrostatic instruments has a mechanism to measure the strength of this electric field.
In measuring the electric field strength, the measured value depends greatly on the distance between the sensor and the object. As the distance from the object to be measured increases, the number of lines of electric force decreases and the measured value becomes smaller. It also depends on the size of the object to be measured. As the area of the object becomes smaller, the measured value becomes smaller than it actually is.
A measurement system called a voltage feedback type surface potentiometer is an ingenious solution to the problem of measurement distance dependence. This is a measurement method in which a voltage is applied to the sensor in a situation where the sensor is brought close to the object, and the value measured is recorded as the voltage of the object, such that the electric field strength is zero.
In addition to distance and size, there are other factors that affect the measurement. Grounding of the measuring instrument is important for accurate measurements, as any static charge on the human body can affect the measurement. Humidity control during measurement and proper calibration are also required.
How to Use Electrostatic Instruments
Electrostatic instrumentrs are device that quantitatively measures the electric charge on the surface of an object to be measured. The device generally consists of a non-contact sensor that is pointed at the object to be measured and a main unit that calculates and displays the information obtained from the sensor. Some devices have the sensor and the main unit integrated into one unit. The device is also referred to as a "charge potential meter," "surface potential meter," etc. The measured values are displayed in units of voltage.
The measured value is displayed in volts (00V), the unit of voltage. Note, however, that the display unit differs from kV and V in proportion to the magnitude of the charge. In static electricity measurement, the device to be selected depends on the magnitude of static electricity to be measured. Therefore, it is necessary to first find out the kVmeasuring range kV of the device. Also, when measuring static electricity, the measurement distance between the sensor and the object to be measured is determined. Please note that if the measurement is not made within the range of the equipment specifications, the correct value will not be obtained.
