TAKIKAWA Japan 

non-contact orthogonal dual-axes laser scanning micrometer
Model: LDM-303H-XY (includes LDM-130EX)

The TAKIKAWA LDM-303H-XY is a high-precision, non-contact orthogonal dual-axes laser scanning micrometer used for measuring the outer diameter of various objects

Features and Applications

• Orthogonal Dual Axes (X/Y): The unit provides simultaneous measurement along two perpendicular axes, which is ideal for accurately measuring the outer diameter of round, elliptical, or flat objects like wires and cables.
• Non-Contact Measurement: By using laser light, the micrometer measures soft materials like rubber or silicone tubes without deforming the object or causing scratches on its surface.
• Versatile Use: It is used across various industries to measure objects such as:
  • Medical tubes (catheters, infusion tubes)
  • Rubber and plastic hoses (automotive fuel lines, air hoses)
  • Electric wires and cables (optical fibers, high-voltage wires)
  • Metal pipes (stainless steel, copper, aluminum)
• Immunity to External Light: Measurements are stable and not affected by external light sources like sunlight or fluorescent lamps.
• System Integration: The LDM-303H-XY is typically connected to a separate display unit (eg, LDM-110, LDM-210 series) for data processing, display, and advanced functions like statistical process control (SPC), high/low alarms, and data output via RS-232C or BCD (optional) interfaces.
• High-Temperature Measurement: The unit can be optionally modified to measure objects at high temperatures (up to 2000°C)

The combination of the TAKIKAWA LDM-303H-XY scanning unit and the LDM-130EX display unit creates a high-performance system for precise, non-contact, online measurement of outer diameters and object dimensions in industrial settings.

• LDM-303H-XY (Scanning Unit): This unit is an orthogonal dual-axes laser micrometer. It emits a laser beam that scans across the object 400 times per second, measuring the object's dimensions along both the X and Y axes. This dual-axis capability is especially useful for checking the flatness or ovality of non-perfectly round objects.
• LDM-130EX (Display Unit): The LDM-130EX receives the raw signals from the LDM-303H-XY, processes them into meaningful measurements, and provides the user interface and connectivity.

• Data Display & Calculation: It displays instantaneous values and calculates essential metrics such as maximum, minimum, and average measurements.
• Multi-axis Calculation: It performs calculations specific to dual-axis measurements, such as average, difference, sum, ratio, and flatness.
• Process Control: It offers features for controlling production processes, including:
  • High/Low Alarms: Outputting signals when measurements fall outside pre-set limits.
  • External Control: The unit can be combined with a diameter control unit (like the DAC-86B) or a PLC (Programmable Logic Controller) for automated outer diameter control.
• Connectivity: It provides various interfaces for data collection and integration into production systems, including RS-232C, analog output, MODBUS-RTU, and optional Ethernet/IP or CC-Link support.
• Data Management: Users can read and write setting values with a USB memory stick for easy configuration and data logging.
