The digital gauge counter DG-4320/DG-4340 inputs signals from a linear gauge sensor and precisely measures and displays dimensions and displacements. It adds new features necessary for measurement, such as calculation functions and condition storage functions, demonstrating its capabilities for inline measurement in production sites.

* The display example of DG-4340 (in red) is when the comparator indicates NG.
When the OK judgment is made, it will display in green, similar to DG-4320.

Features

  • Ono Sokki Compatible with all linear gauge sensors (except GS-3800B series)

  • Step multiplication switching, panel condition memory, and various functions such as MAX, MIN, and RANGE calculations.

  • Compatible with 12 V power supply sensors (optional)
    Counts signals from single-phase pulse signals such as rotation detectors or from encoders.

  • With the 3ch comparator function, it is possible to determine the pass or fail of parts and products (DG-4340)
    When the comparator operates, the backlight of the display screen changes to red, making it easy to understand.

Connection and Communication

The BCD output of DG-4320/DG-4340 is generally equivalent to the pin assignment and connector of DG-4140.
However, due to new features, pins that were previously unused in older models are now utilized. Additionally, the comparator output terminals present in DG-4240/DG-4280 are not available.

Case Studies

Pass/Fail Judgment by 3ch OK/NG Comparator Function

By detecting the height of the screw, you can check the tightness of the screw.
Equipped with a 3-channel OK/NG comparator, it can accommodate three types of screws of different sizes.

Pass/Fail Judgment by 3ch OK/NG Comparator Function

In the flatness inspection of parts, a sensor is applied to the subject and rotated once.
By looking at the RANGE value (MAX-MIN), flatness measurement can be easily performed.

Length measurement using pulse counter function

The length of paper or steel plates is measured using a rotary encoder attached to the feed rollers.
By using the multiplication switching function and factor setting function, the pulse output from the encoder can be converted into length.

Automatic identification by BCD output function

We will determine whether the dimensions of the processed parts are within the standards. By inputting BCD output into the sequencer, sorting can be performed based on the measurement values.
