displacement measurement transducer

Kingmach displacement measurement transducer include the JMDL-49XXAT Smart Formwork Displacement Meter, also described as a steel wire displacement meter for high-formwork support, horizontal movement of formwork steel pipes, slope sliding, bridge abutments, tunnel portals, dams, and railway subgrades. Listed ranges include 50 mm, 100 mm, and 200 mm, with 0.01 mm sensitivity and 0.5%FS accuracy. The product uses patented inductive magnetic flux modulation technology, non-contact measurement, 20-point calibration curve correction, a built-in memory chip, and digital detection. It stores model, serial number, calibration coefficients, time, temperature, displacement values, and other records, with up to 600 stored data sets. The construction-grade details are important: product information lists IP68 protection, a 30-year service life, and a temperature range from -40 degrees Celsius to +100 degrees Celsius with plus or minus 0.5 degrees Celsius temperature accuracy. These features make it suitable for wet, dusty, and high-load construction environments. 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.
