Non-contact Thickness Meter
CL-5600 series
Electrostatic capacitance-type |
|
 |
The CL-5600 Series non-contact thickness
meters use an electrostatic capacitance-type gap detector to measure
conductors, semiconductors and insulators. The VE Series
electrostatic capacitance-type gap detectors have shown proven
results as non-contact electrostatic capacitance-type sensors, and
enable high-accuracy, stable thickness measurement using easy
operations. The CL-5600 Series offers both a conductor/semiconductor
measurement function that uses two sensors (standard) and an
insulator measurement function (option: CL-0300) that uses one
sensor. Featuring a new outward appearance and enhanced functions,
they utilize the revamped electrostatic capacitance-type converters,
the VE Series gap detectors. The measurement range has been
expanded, and an easy-to-read fluorescent display has been utilized
for the display unit. Moreover, the separation of the gap converter
from the main unit enables the addition of an analog output, a
comparator function (option: CL-0100) and a high-resolution display
function (option: CL-0200) for even more flexibility and improved
ease of use. |

Measurement methods
|
When measuring conductors or semiconductors |
When measuring insulators (CL-0300 Insulator
measurement function) |
|
Install two sensors in parallel
within the measurement range for the target measurement
object. Specify the space (Gs) between these two sensors
at the CL-5600 Series. Insert the target measurement
object between sensors A and B and measure the gap
between each sensor and the target measurement object (Ga
and Gb) to obtain the thickness (t).
Note:
The sensor case and the material are assumed to have
equal potential. |
Specify the space (Gs) between the
sensor and the conductor (reference area) at the CL-5600
Series. When the target measurement object is inserted
between the sensor and the conductor (reference area),
the sensor output becomes Ga. The thickness (t) is
obtained from the amount of change in the sensor output
and the relative dielectric constant
εr.
εr.:
Dielectric constant (When the dielectric constant of a
vacuum is 1 the dielectric constant of the target
measurement object is referred to as the relative
dielectric constant.)
Note:
The sensor case and the material are assumed to have
equal potential. |
Object can be measured
|
Conductors, semiconductors (when using the CL-5600 or
CL-5600S’s standard functions) |
Insulators (when using the CL-0300 option’s
additional function) |
|
Metal, conductive materials such as
silicon wafers, double-sided copper-clad laminated
plates, pastes. Carbon plates. |
Thin objects that are composed of a
uniform, simple material throughout can be measured.
Relatively thin objects such as glass, crystal wafers,
sapphire wafers, film and plastic. |

between the surface of the sensor tip and the object
under measurement.
*2: The surface measurement area of the object under
measurement must be larger than the external diameter of
the sensor.
*3: The operating temperature range is the temperature
range in which the sensor can operate, not the operating
range for which accuracy is
guaranteed. The operating range for which
accuracy is guaranteed at 23±2°C. The temperature
