Non-contact Thickness Meters/Displacement Meters (Electrostatic capacitance type) Non-contact displacement meters Non-contact thickness meters New advances have been made in displacement meters and thickness meters that use electrostatic capacitance, a method which has an established reputation for accuracy and stability. Non-contact measurement can now be performed in nanometer resolution, and a frequency response of 10 kHz has been realized. These instruments meet a wide range of applications, including the measurement of the thickness of conductors and semiconductors, and of the axial runout of rotating objects. They can be incorporated into production lines, and used for applications such as quality control and testing in a wide variety of fields.

VT-5200/5700 Series Electrostatic capacitance-type non-contact displacement meters Caution The electrostatic capacitance-type gap detectors, the electrostatic capacitance-type non-contact displacement meters and the electrostatic capacitance-type non-contact thickness meters are not, in principle, provided with an over-voltage safeguard for the sensors or sensor amplifiers. If the object under measurement is electrically charged, the sensor amplifier may be damaged. In addition, to prevent an adverse effect on the measurement accuracy, be sure to affix anti-static...

VE Series Electrostatic capacitance-type gap detectors Measurement principle The VE Series gap detectors measure and display the gap (displacement) from the electrostatic capacitance between the sensor and the target measurement object. The electrostatic capacitance C is a function of the area of the conductor that is facing the sensor S and the gap D. If the sensor and the conductor that it is facing (object under measurement) are parallel flat plates, we can use the following equation to obtain the gap D by measuring the electrostatic capacitance C. C= Sensor D : dielectric constant Objects...

Sensor calibration Gap measurement cannot be performed when the target measurement object is an insulator. Examples of insulators include the following. (With a non-contact thickness meter, the thickness is obtained from the dielectric constant and calculation performed. Please refer to the section on non-contact thickness meters.) In order to keep the specified accuracy, the calibration has been performed for one-to-one each other of the sensor with the converter or the display unit before delivery. Recalibration is required if the sensor shall be replaced. • Plastics • Plastic film • Sapphires...

CL-5600 Series Electrostatic capacitance-type non-contact th Outline The CL-5600 Series non-contact thickness meters use an electrostatic capacitance-type gap detector to measure conductors, semiconductors and insulators.
