    LDM-PCEX2 - Laser Diameter Measurement System

    LDM-PCEX2 is a software application that takes the result measured using Takikawa's laser diameter from the display part into the PC by serial communications (RS-232C), and to file the graph print and the measurement result

     

    Encoder system unit (option)

    This unit greatly enhances the function of the LDM-PCEX2:

    ・ Start/Stop of measurement data recording can be done by external switch , output  ,  reading of a rotarly encorder. 
    ・This has USB <-> RS-232C converter .  Even if PC has no RS-232C , connectable by USB cable.

     

    Quality Control Application

    The application reads the data acquired by LDM-PCEX2 and creates a quality control valiue and various graphs. The process variation.of the products can be grasped and can be judged objectively with a quality control index.

      Quality control application
     Measurement Display

     Displays acguired measurement data as graph:

    1. Displays all maximum/minimum in every section in display.
    2. The average value plot of each section
     Histogram  It is possible to see the variation state of measured value visually.
     Quality Control Index  Calculated values, such as the maximum/minimum, an average / standard deviation  value, distribution/deviation, and a process capability index (Cp/Cpk), are displayed.
     Graph display  Selection is arbitrarily possible in display ch selection convenient to print or a plot color.

    Example of the use of an encoder system unit

     

    ・The ability to count pulses from the rotary encoder is added by using an optional encoder system unit. The horizontal axis of the       graph generally is time display, by using this option, it is possible to display the horizontal axis of the graph distance is possible.

        RS232C port is also provided together can also be connected to the LDM display unit.

     

    Constitution
    Connected as shown below each device and the encoder system unit.

     

    ・Rotary encorder and recording On/Off switch can be connected in accordance with the needs of customers.
