CL-5610シリーズ

Connection configuration of CL-5610 / CL-5610S

The CL-5610/CL-5610S are non-contact thickness gauges that measure the thickness of conductors, semiconductors, and insulators by connecting to VE series gap detector sensors. Up to two VE series sensors can be connected. They can also be used as 2-channel gap gauges. The CL-5610 has a built-in sensor amplifier, and the VE sensor is connected directly to the thickness gauge body. It is suitable for offline measurements on a desktop (the cable between the sensor and body is 1.5 m and cannot be extended). The CL-5610S has an external, independent sensor amplifier, and the VE sensor and thickness gauge body are used separately. The cable length between the body and the external amplifier is 2.5 m as standard, and can be extended up to 10 m with options. It is suitable for installations where the sensor and thickness gauge body need to be separated, such as integration into equipment.

Features

Numerous measurement items

It can measure thickness and gap. Additionally, it can display calculated values for each, including standard deviation, maximum value, minimum value, and maximum width (maximum - minimum).

In addition to conductors and semiconductors, the thickness of insulators can also be measured.

The CL-0300's insulating material measurement function (optional) allows you to measure the thickness of insulating materials such as thin plastic films and glass plates.

Even samples that do not have complete conductivity can be measured with stable thickness.

When holding a sample on a table coated with a fluorine-based film, it was difficult to ensure electrical conductivity between the sample and the main unit (common). Previously, stability had to be ensured by contacting the sample over a large area, but the CL-0210 high-impedance grounding mode function (optional) allows for a reduction in that area. Furthermore, higher stability can be ensured within the same area.

The high-resolution calculation function option (CL-0200) achieves a minimum display resolution of 0.02 μm. *1

*1 When using VE-2011/VE-5010/VE-5011. Applies to VE-5010/VE-5011 when the measurement range is set to 20-200 μm using the CL-0201 measurement range change option.

Up to 6 different sensor calibration values can be saved.

The CL-5610 series can store up to six sets of sensor calibration information, allowing you to select and use the optimal sensor according to your measurement range and resolution.

It is possible to continuously acquire data into a PLC or PC.

Three types of data output functions are available: analog voltage output, BCD output, and RS-232C. You can select the output that best suits your recording device. Analog and BCD outputs allow you to retrieve data at a data update interval of 20 ms. By measuring while moving the sample, you can also measure continuous thickness values necessary for detecting thickness variations in sheets.

*Analog output requires the output function option (CL-0110), and BCD output requires the BCD output function option (CL-0120).

This device can be controlled externally.

For automated measurement on manufacturing and inspection lines, it is necessary to control this device externally. The CL-5610 comes standard with contact control terminals and an RS-232C terminal, allowing for easy control from a PLC or PC.

The comparator function (when the CL-0110 output function option is installed) allows for online monitoring of abnormal values.

Example of measurement sample

Conductors and Semiconductors insulator
Silicon wafers, steel plates, aluminum plates, hard disks, printed circuit boards, and other metal plates that require cleanliness, are soft, have a mirror finish, or are easily scratched. Glass, polyethylene, polypropylene, and other plastics.
(The objects to be measured are thin objects composed of a single material with uniform properties throughout.)

Case Studies

When measuring conductors and semiconductors

When measuring conductors and semiconductors

Two sensors and the object to be measured are placed parallel to each other within the sensor measurement range, and this sensor spacing (Gs) is set in the CL-5610 series. The object to be measured is inserted between sensors A and B, and the gap (Ga, Gb) between each sensor and the object is measured to determine the thickness (t).

When measuring insulators (optional)

When measuring insulators (optional)

The sensor and conductor (reference floor) are set parallel to each other, and the sensor's gap measurement (voltage output Gs at this time) is set in the CL-5610 series. When the object to be measured is inserted between the sensor and the conductor (reference floor), the sensor's voltage output becomes Ga, and the thickness (t) is determined from this change in sensor voltage and the relative permittivity εr.

*The measurable thickness of the insulator should be approximately 1/3 or less of the GAP value between the sensor and the reference floor.
