portable tiltmeter
The JMZX-7100L sliding inclinometer is a field profiling instrument within the Kingmach portable tiltmeter group. It is used for measuring horizontal displacement changes inside soil masses in dams, building foundations, embankment slopes, underground construction projects, geotechnical slopes, and port engineering. The instrument combines a sliding inclinometer probe with a 3D-MEMS silicon capacitor biaxial inclinometer sensor and an integrated testing instrument. It supports mobile phone APP reading, Bluetooth transmission, large storage capacity for millions of readings, data download for numerical and graphical analysis, real-time wireless network sending, Chinese and English menus, and dedicated post-processing software. Published specifications include +/-90 degrees sensor range, 500 mm guide wheel spacing reference, a probe size of 26 mm by 776 mm, 8.5 kg total weight, 2 kg probe weight, -20 degrees Celsius to +60 degrees Celsius operation, 180 m water pressure impermeability, and 100 g vibration resistance.
Application of portable tiltmeter
Port and underground construction projects use portable tiltmeter to follow soil movement, retaining structures, and deep displacement where surface survey alone is limited. JMZX-7100L is described for port engineering and underground construction projects, with Bluetooth communication, APP reading, large storage, and post-processing software. The sliding probe method is useful when engineers need a deformation profile along an inclinometer casing rather than one fixed surface angle. Field crews should keep casing ID, depth interval, probe orientation, reading direction, groundwater condition, and operator notes consistent. Data can then be compared with excavation, dredging, surcharge loading, pile work, or retaining wall movement. Good field discipline prevents a profile change from being confused with probe handling differences.
The future of portable tiltmeter
Low-power acquisition will matter more for future portable tiltmeter in remote or difficult sites. JMQJ-7915ATS includes a low-power mode that powers sensors only during measurement, and JMQJ-7315RTU uses battery-based wireless operation. These features are important for slopes, dams, railways, and temporary construction areas where mains power or frequent access may be limited. Future systems will likely use smarter wake-up intervals, battery health reporting, and power-aware sampling plans. The goal is not to reduce monitoring quality; it is to match energy use to the risk level and deformation speed. A stable slope may need slower readings, while an active excavation or storm period may need denser data. Power planning will become part of measurement planning.
Care & Maintenance of portable tiltmeter
Borehole systems for portable tiltmeter need careful mechanical and data maintenance. JMQJ-7915ATS uses a multi-point tandem inclinometer string with universal joints, connecting rods, suspension, cables, and an orifice acquisition module. During installation, record measurement spacing, borehole ID, casing condition, orientation, group assignment, and factory configuration. During inspection, protect the orifice, check cable strain, review module status, and compare depth points for abnormal jumps. If one depth changes sharply while neighboring depths remain steady, inspect both the ground condition and the instrument chain. Borehole data is most useful when every depth point remains tied to a clear physical position and a stable orientation reference.
Kingmach portable tiltmeter
For automated monitoring, Kingmach portable tiltmeter can reduce the need for repeated manual survey work in hidden or hazardous locations. Fixed and integrated units can connect to acquisition systems, while in-place inclinometer strings can collect multi-depth data through an orifice module. JMQJ-7315RTU is designed for remote unattended automatic measurement using 4G wireless communication. JMQJ-7915ATS supports wired or wireless upload from the acquisition module, and its low-power mode activates sensors only during data measurement. These features matter where access is restricted by traffic, excavation, weather, or operating infrastructure. Automation does not remove the need for field checks, but it gives owners a continuous record that can be compared with rainfall, groundwater, blasting, train operation, loading, or nearby construction events.
FAQ
Q: How should portable tiltmeter be installed?
A: The mounting surface or borehole position should be stable, the axis direction must be recorded, and the baseline should be saved after the instrument settles.Q: Why is axis direction important?
A: Tilt values only have engineering meaning when the positive and negative directions are tied to the structure, slope, tunnel, or borehole drawing.Q: Can these instruments work in wet sites?
A: Several Kingmach models list IP65, IP67, or IP68 protection, but glands, connectors, cabinets, and cable entries still need field inspection.Q: What should be checked during commissioning?
A: Check model, range, serial number, communication, power, baseline, point name, mounting photo, channel address, and related site condition.Q: Can a tiltmeter be reset after installation?
A: It can be re-baselined when necessary, but the old value, new value, reason, date, and technician should remain visible in the record.
