non contact displacement transducer

Kingmach positions its non contact displacement transducers as dependable mid-range instruments built for geotechnical and structural health monitoring. Unlike contact probes that wear out at the sliding point, these sensors use eddy current, laser, or draw-wire optical measurement principles, depending on the application. For a typical tunnel convergence station or a crack monitoring point on a dam, the team often recommends an eddy current type when the target surface is metallic and stable, or a laser-based unit when working with concrete or rock surfaces where standoff distance is important. The signal conditioning electronics are packed into a compact, IP65-rated sealed body with surge protection, so the units hold up in the damp and electrically noisy environments common to construction sites. A standard analog output (4-20 mA or 0-10 V) means they plug directly into most industrial DAQ systems without extra signal converters. Where networks are already in place, RS-485 digital versions simplify long-distance data collection. Kingmach’s engineering group also handles special requests, such as extended temperature compensation from -30°C to +70°C or brackets designed for awkward mounting angles on aging infrastructure. The result is a transducer that gives clean, repeatable data over years of service, not just spot readings, and that reduces the time field crews spend recalibrating or replacing failed units. With distribution partners in several regions and in-house technical support, Kingmach aims to shorten the gap between ordering a sensor and getting useful data from it.
