Length Measurement Sensor for Wire Feed Mechanisms

Product Specifications

Technical details and manufacturing context for Length Measurement Sensor

Definition

The Length Measurement Sensor is a precision component used in wire feed mechanisms to monitor and measure the exact length of wire dispensed. It employs optical, magnetic, or mechanical sensing technologies to convert the physical movement of the wire into electrical signals proportional to length, ensuring accurate wire feed control. The sensor is typically integrated into the feed path, where it detects wire movement without contact or via a measuring wheel. Its output signal, typically 4–20 mA analog, can be interfaced with control systems for real-time monitoring and process automation. The device is available in configurations with a measuring range of 0.1 to 100 meters, resolution down to 0.001 mm, and accuracy of ±0.05% of measured value, with repeatability of ±0.02%. It operates on a 24 V DC supply (reverse polarity protected) and is designed for industrial environments with an operating temperature range of -10°C to 60°C, noting that accuracy degrades below -10°C. The sensor offers protection classes from IP54 to IP65 per IEC 60529, suitable for dusty conditions. The measuring wheel is made of aluminum, with hardened steel optional. Cable lengths range from 2 to 10 meters (shielded), and the unit weighs between 0.5 and 1.5 kg depending on configuration. Materials used include stainless steel, aluminum alloy, and optical glass. This sensor is a component for machinery and equipment manufacturing, and its specifications are reference values that must be verified with the manufacturer for the specific model and application.

Working Principle

The sensor operates by detecting wire movement through various methods. Optical encoders read marks on the wire, magnetic sensors detect the passage of wire, or contact wheels measure rotation. These methods convert physical movement into electrical signals proportional to the length of wire fed. The signal is then processed and output as a 4–20 mA analog signal for integration with control systems.
