settlement gauge

Kingmach’s settlement gauges are designed for long-term pore pressure and settlement monitoring in soils and rock. The key components—a sensor element and a liquid-filled tube system—are arranged so that the gauge references a stable datum away from the deforming zone. This approach is common for measuring settlement under embankments, behind retaining walls, or around deep excavations. The sensor is typically a high-resolution vibrating wire unit with built-in temperature compensation. This combination helps reduce thermal effects on readings, which matters when monitoring spans years rather than months. Accuracy depends on installation quality and site conditions; typical systems achieve sub-millimeter resolution under steady temperatures. The gauge housing is stainless steel, and the sensor is protected against moisture ingress—practical details that extend field life in wet boreholes. From a project logistics point of view, Kingmach offers settlement gauges in a standard range of measurement lengths and can produce custom lengths on request. The data output is compatible with most dataloggers that accept vibrating wire signals, so no proprietary readout is forced. Over the years, we have supplied these instruments to dam safety programs, high-speed rail construction, and metro tunnel projects across several continents. Each shipment includes calibration records, and we can arrange technical support for installation training either remotely or on-site. Routine maintenance mostly involves checking the liquid levels in the reference system, and replacement parts are kept in stock.
