Displacement Transducers for Field Monitoring
Monitoring ground movement or structural displacement often comes down to having sensors you can actually count on in rough conditions. Kingmach supplies displacement transducers that get used in dams, tunnels, slopes, and deep excavations. These aren't lab instruments—they are built to handle real site work. Our range covers linear potentiometric, LVDT, and draw-wire types, with customization possible if standard specs don't match your project. While we don't list every parameter here, the core idea is straightforward: accurate, long-term displacement data without constant recalibration.
Technical Detail
Kingmach Measurement & Monitoring Technology Co., Ltd. offers displacement transducers as part of a wider line of geotechnical instruments. The units are designed to measure movement over time—crack opening, joint slip, settlement, lateral displacement. Many of our transducers use potentiometric sensing with good linearity and repeatability. Housings are typically stainless steel or aluminum with IP65 or higher sealing, which matters when they sit in wet concrete or drilling fluid. Signal output is commonly 0-5V, 4-20mA, or digital, making integration with data loggers and automated monitoring systems fairly direct. We also supply LVDT-based sensors for higher precision requirements. For projects with unusual rod lengths or cable exits, we can often adapt existing designs. The main idea is to give you dependable displacement data that feeds into your stability analysis, whether you're monitoring a deep foundation pit or a landslide-prone slope.

Typical non-linearity for our potentiometric types is under 0.3% of full range, while LVDT models can reach 0.1% or better. Actual performance depends on the selected range and mounting, so it's best to discuss your tolerance requirements with our team.
Yes, they are built with weather sealing in mind. Most come with IP65-rated bodies and sealed connector heads. For burial or submerged applications, we can provide higher IP ratings and stainless steel rods.
Potentiometric types are simpler, generally less expensive, and work well for ranges from 25 mm up to several meters. LVDTs are frictionless and give better resolution, so they suit small-deflection monitoring where precision is critical, like in laboratory rock testing or structural health monitoring.
Custom cable lengths are common, and we can fit connectors from brands like Amphenol or Binder. If you have a specific data acquisition system, let us know the pinout; we often wire sensors to match.
