Smart Single-Point /Bedrock Displacement Meter

Kingmach Smart Single-Point /Bedrock Displacement Meter include the JMCW-21XXADT Magnetostrictive Displacement Meter for absolute linear position measurement. This sensor uses magnetostrictive effect and internal non-contact sensing, which avoids mechanical wear and supports continuous operation in harsh environments. Product information lists 0 to 1000 mm measuring range, 0.01 mm resolution, plus or minus 0.05%FS accuracy, repeatability within 0.1 mm, DC24V plus or minus 10% input, RS485 communication, average operating current below 60 mA, and an operating temperature range from -30 degrees Celsius to +80 degrees Celsius. It also lists IP67 protection and reverse polarity protection up to -36V. Wiring details include red for DC24V, yellow for power ground, blue for RS485A, and green for RS485B. These features make the product suitable for hydraulic cylinders, gate position, machine stroke, structural deformation, railway and highway movement, retaining walls, and industrial automation equipment that requires stable absolute position data. During project setup, the measuring point should be matched with the expected travel direction, available mounting space, cable route, and required acquisition interval. This prevents a short-range joint instrument from being used on a long-travel point, or an exposed sensor from being placed where an embedded anchor is needed. It also helps the monitoring team set a baseline that can be defended during acceptance and later maintenance review.
