Smart Single-Point Settlement Gauge
Kingmach Smart Single-Point Settlement Gauge 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 Smart Single-Point Settlement Gauge
In dam monitoring, Smart Single-Point Settlement Gauge are used for long-term observation of dam body settlement, gallery deformation, foundation movement, and vertical change near water-control structures. This work has a slow rhythm: reservoir level, seepage, rainfall, seasonal temperature, and consolidation history may all affect the curve. Kingmach JMQJ-62XXADT gives micro range hydrostatic measurement with IP68 protection and 0.01 mm resolution, while JMYC-62XXAD provides wider 500 mm to 4000 mm ranges for larger vertical displacement. JMDL-62XXADT can form a multi-point hydrostatic leveling network when several positions must be compared from one reference. A dam layout should treat the reference location, tube route, cabinet position, cable protection, and access path as part of the measurement system. During operation, engineers should review settlement data with reservoir records, seepage flow, piezometer behavior, inspection notes from galleries, and downstream observation results. The goal is to see whether a slow trend matches expected consolidation or whether it appears near a structural joint, foundation zone, or water level event. Good records make annual dam-safety review more traceable and reduce confusion when readings are checked years later.
The future of Smart Single-Point Settlement Gauge
Future Smart Single-Point Settlement Gauge reports will need to be clearer for both engineers and owners. A useful settlement report should show baseline date, latest value, cumulative settlement, rate of change, reference point status, water level condition, construction stage, and recommended inspection action. It should also include whether the reading was manual, remote, magnetic ring based, hydrostatic, or embedded single-point measurement. Kingmach products generate different kinds of settlement information, so reporting should preserve that context instead of flattening every value into one table. For high-risk projects, trend graphs should sit beside field notes and photos. That makes it easier to decide whether a movement is normal consolidation, reference disturbance, water-related change, or a condition that needs immediate review. 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 Smart Single-Point Settlement Gauge
Replacement or recalibration of Smart Single-Point Settlement Gauge must preserve continuity in the settlement record. Do not overwrite earlier data or silently move the zero value. Record replacement date, reason, model, range, serial number, reference point, first stable reading, and any change to cable, tube, cabinet, borehole, or mounting setup. If a hydrostatic reference point is moved, explain how old and new readings should be compared. If a magnetic ring borehole is repaired, note whether depth references changed. If an embedded gauge is abandoned, mark the point status clearly in reports instead of leaving a silent gap. Settlement monitoring often matters because it lasts for years, so maintenance events must be visible to future reviewers. A clean handover file should let a new engineer understand not only the curve, but also every instrument event that shaped it.
Kingmach Smart Single-Point Settlement Gauge
Smart Single-Point Settlement Gauge become most useful when they are part of a disciplined data chain. The sensor body is only one part of the record. Reference point, water tube route, cable label, borehole number, ring depth, bus address, platform unit, baseline, and inspection note all shape whether the final curve can be trusted. Kingmach products support both manual reading and automated acquisition, so the same project may combine field tape readings, RS485 data, bus modules, and software reports. During commissioning, each channel should be checked against the physical point. During maintenance, data gaps should be compared with power, communication, weather, and cabinet work. This makes settlement monitoring less mysterious and more useful to the people who must act on it. When those details are settled before installation, the sensor has a much better chance of producing a reliable curve throughout the project life. When those details are settled before installation, the sensor has a much better chance of producing a reliable curve throughout the project life.
FAQ
Q: What does JMDL-47XXAT measure?
A: It measures in-situ subgrade settlement, embankment heave, foundation pit base uplift, tunnel bottom uplift, dyke compression, and pile foundation settlement.
Q: What ranges are listed for JMDL-47XXAT?
A: The listed ranges are 100 mm, 200 mm, 300 mm, and 400 mm, with 0.01 mm resolution on the 100 and 200 mm models and 0.1 mm on larger models.
Q: How is the gauge installed?
A: It uses a settlement plate, electrical displacement sensor, measuring rod, metal flexible conduit, anchor head, extension rod, and bottom anchor head.
Q: Can traffic operation continue during monitoring?
A: The side-exit cable routing is designed to avoid interference with pavement compaction and can support monitoring during traffic operation when installed correctly.
Q: What should be recorded during installation?
A: Record plate position, anchor depth, extension length, cable route, baseline, model, range, and construction stage.
