Omnidirectional Displacement Meter

The JMLS-22XXADT Wire Rope Displacement Sensor broadens Kingmach Omnidirectional Displacement Meter into long-travel and flexible-path displacement measurement. It uses a retractable plastic-coated stainless steel cable wound around a spool and a precision rotary sensor. When the cable extends or retracts, resistance changes are converted into displacement data. Listed ranges include 0 to 500 mm, 0 to 1000 mm, and 0 to 2000 mm. Product information gives 0.1 mm resolution, 0.2%FS accuracy, DC 9V to 24V operating voltage, power consumption at or below 0.3 W, RS485 communication at 2400 bps, IP67 sealing, operating temperature from -30 degrees Celsius to +70 degrees Celsius, dimensions of 115 mm by 85 mm by 100 mm, and approximately 1 kg weight. The product supports linear and curved displacement monitoring, making it useful for dam monitoring, geohazard prevention, tunnel clearance, machinery position, soil and rock movement, and long-distance movement between two points. 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.
