Single-point Settlement Meter
Kingmach Single-point Settlement Meter cover several ways to measure vertical deformation on civil and geotechnical projects. The category includes the JMDL-47XXAT smart single-point settlement gauge, JMDL-62XXADT inductive frequency-modulated hydrostatic level sensor, JMQJ-62XXADT micro range hydrostatic level sensor, JMYC-62XXAD wide-range differential pressure hydrostatic level sensor, and JMCJ-1003/1005 magnetic ring settlement water level gauge. Each product answers a different field question. A buried single-point gauge follows one embedded location in a roadbed, foundation, dyke, or tunnel invert. A hydrostatic network compares several elevations through connected liquid lines. A wide-range differential pressure system handles larger movement during reclamation or soft foundation treatment. A magnetic ring gauge separates layered underground compression from groundwater level change. Selection should begin with expected travel, required resolution, manual or automatic reading mode, access after burial, reference stability, and the structure being observed. This product group gives engineers a practical set of instruments for turning slow ground movement into named measuring points, dated baselines, and repeatable readings.
Application of Single-point Settlement Meter
Building projects use Single-point Settlement Meter when a foundation, basement, column line, retaining wall, or adjacent ground area needs a dated vertical movement record. The work often starts before the permanent structure is complete: excavation, dewatering, pile work, concrete loading, and backfilling can all change elevation patterns. Kingmach JMDL-47XXAT is relevant to pile foundation settlement and base uplift in deep foundation pits, while JMDL-62XXADT or JMQJ-62XXADT hydrostatic sensors can compare several building points from one reference. A useful layout may follow a gridline instead of only the most visible cracks, because differential movement across a structural bay is often more important than one isolated value. The record should connect each channel to a floor level, nearby column or wall mark, construction date, water condition, and visual inspection note. If one side of a basement drifts while another remains steady, the trend can guide more focused review. For occupied buildings, stable wiring, protected cabinets, and clear point labels matter because readings may continue through many inspection cycles.
The future of Single-point Settlement Meter
Future Single-point Settlement Meter will use smarter edge checking before data reaches the main platform. A sudden settlement jump may come from real ground movement, but it may also come from a disturbed tube, loose cable, air pocket, dewatering activity, cabinet work, or reference point change. Acquisition units can compare settlement rate, water level, rainfall, temperature, and nearby channels before marking a value as reliable. Kingmach products with RS485 output and automated acquisition compatibility already provide a basis for this kind of review. For remote railway subgrades, dams, tunnels, and slopes, early filtering can reduce unnecessary field visits while still flagging readings that need inspection. The aim is not to hide abnormal movement, but to separate data-chain faults from structural behavior faster. The practical goal is to keep settlement data understandable after the original installation crew has left, so owners can compare old and new readings without reconstructing the field history from memory. The same record should remain readable for designers, contractors, owners, and maintenance teams, because settlement monitoring often continues long after the first construction report is finished.
Care & Maintenance of Single-point Settlement Meter
Embedded Single-point Settlement Meter such as JMDL-47XXAT require protection during earthwork, paving, and later traffic. The settlement plate, measuring rod, metal flexible conduit, anchor head, extension rod, bottom anchor, and side-exit cable should be installed without being bent or crushed by compaction equipment. Record installation depth, gauge length, cable exit point, fill layer, protection cover, and first stable reading before the point is buried. During maintenance, inspect accessible cable sections, junction boxes, cabinet terminals, and any area where later excavation may have disturbed the line. If a curve changes after a filling stage or pavement operation, compare the timing with construction logs before judging the ground response. Buried parts are difficult to inspect after coverage, so photographs, as-built sketches, and cable route notes become part of the working instrument. Good embedded-point care is mostly quiet prevention done before damage becomes visible.
Kingmach Single-point Settlement Meter
Wide-area settlement monitoring needs Single-point Settlement Meter that can handle larger travel and uneven profiles. Kingmach JMYC-62XXAD wide-range differential pressure hydrostatic level sensors are designed for pavement settlement, cross-sectional nonlinear settlement, soft foundation treatment, land reclamation foundations, dam subgrades, slope stability, bridge deflection, and building settlement. The listed range extends from 500 mm to 4000 mm, with 0.1 mm resolution and 0.2%FS accuracy. This makes it different from micro range sensors used for smaller deflection changes. A long road or reclamation section should not be judged by one point only. The value comes from comparing a profile over time, then linking that profile with filling stage, surcharge timing, drainage records, groundwater, and site inspection notes. This is especially important when several instruments share one cabinet or when hydrostatic tubes, embedded rods, and manual borehole readings appear in the same project.

FAQ
Q: What is JMCJ-1003/1005 used for?
A: It is used to measure layered underground settlement and groundwater level in foundations, subgrades, foundation pits, embankments, and underground structures.
Q: How does magnetic ring settlement reading work?
A: Magnetic rings are placed underground; when the probe senses a ring, audible and visual alerts help the operator read depth from the steel tape at the borehole.
Q: How is water level detected?
A: The water level component works by water conductivity and alerts when the probe contacts water.
Q: What accuracy is listed?
A: The listed measurement accuracy is plus or minus 1 mm.
Q: What field records are needed?
A: Keep borehole number, magnetic ring depth, previous reading, current reading, groundwater level, and operator notes together.
