inductive displacement sensor

Most inductive displacement sensors on the market are designed for clean factory floors. Kingmach takes a different route: these sensors are built around field reality. The housing is sealed to IP67 or better, and the electronics are potted to handle condensation and rapid temperature swings. Standard ranges cover from a few millimeters up to 200 mm, with linearity typically within ±0.1% of full scale. For projects that need non-standard ranges or output curves, we can tweak the coil design and calibration without a full custom development cycle. Common configurations include spring-loaded plunger tips for direct contact with concrete or rock surfaces, or threaded bodies that mount easily on steel brackets. The signal output options—4-20 mA, 0-10 V, or RS485 digital—connect directly to most dataloggers used in geotechnical monitoring networks. Because many monitoring campaigns run on tight budgets, we keep the sensor cost competitive without cutting corners on temperature compensation or connector reliability. Installers often comment that the M12 connector orientation and extra-length cable pigtails save them from having to redo conduit runs on site. After deployment, readings typically show drift under 0.1% per year, so you spend less time recalibrating and more time interpreting the data. When a project requires custom documentation, such as individual calibration certificates or specific test reports, our engineering team can provide that without delaying shipment. This mix of practical toughness, configurable parameters, and serviceable technical support has put our sensors into dam monitoring, bridge pier movement studies, and deep excavation projects across multiple continents. We do not try to compete on headline specifications alone; the value is in a sensor that works the same in month twelve as it did after the first rainstorm.
