biaxial tiltmeter
The JMZX-7100L sliding inclinometer is a field profiling instrument within the Kingmach biaxial 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 biaxial tiltmeter
Foundation pit projects use biaxial tiltmeter to monitor retaining wall rotation, support system response, adjacent building tilt, and deep ground movement during excavation. JMQJ-7315ADS can track angular change on exposed structures, while JMQJ-7915ATS can monitor multi-depth deformation inside a borehole. The excavation sequence, dewatering records, support installation dates, rainfall, and nearby settlement points should be reviewed beside the tilt data. If a retaining wall rotates while pore pressure or support force changes at the same time, the pattern deserves closer site checking. A practical layout marks the positive and negative axis direction before excavation begins, protects cables from machinery, and keeps baseline readings tied to excavation depth. This helps the monitoring team separate normal staged movement from a trend that may need immediate engineering review.
The future of biaxial tiltmeter
Low-power acquisition will matter more for future biaxial 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 biaxial tiltmeter
Battery and power checks keep biaxial tiltmeter reliable in remote monitoring. JMQJ-7315RTU uses a 3.6V 38AH battery, while other instruments use DC 9V to 24V power or acquisition modules with standby and operating power modes. Maintenance staff should record battery status, power supply voltage, sleep interval, measurement interval, and any power outage. For low-power systems, confirm that sensors wake correctly during scheduled measurement. For wired cabinets, inspect terminals, fuses, grounding, moisture, and cable strain. A low-voltage condition can create missing data or unstable communication before a total failure appears. Power records are especially important for slopes, bridges, railways, and dams where access may be limited after installation.
Kingmach biaxial tiltmeter
For procurement teams, Kingmach biaxial tiltmeter are not one single instrument type. The product group includes JMQJ-7315ADS fixed tilt sensors, JMQJ-7315RTU integrated wireless tilt units, JMQJ-7915ATS vertical in-place inclinometer systems, JMZX-7100L sliding inclinometers, and JMZX-4QH inclination acquisition modules. Each serves a different monitoring method. A fixed tiltmeter follows one structural point. A wireless integrated unit reduces site wiring. A vertical in-place system reads multiple depths in a borehole. A sliding inclinometer supports field profiling inside inclinometer casing. An acquisition module collects many downhole sensors through grouped communication. A good purchase record should match range, accuracy, communication mode, protection grade, power supply, installation method, and site access. That makes the instrument package easier to install, verify, and maintain after delivery.
FAQ
Q: What are biaxial tiltmeter used for?
A: They measure angular change or internal deformation in bridges, buildings, railways, slopes, dams, foundation pits, tunnels, and other structures where tilt or deep movement must be monitored.Q: Which Kingmach model is used for fixed structural tilt?
A: JMQJ-7315ADS is a fixed MEMS tiltmeter with +/-15 degree dual-axis range, 0.001 degree resolution, RS485 output, and IP68 protection.Q: When is JMQJ-7315RTU useful?
A: It is useful when wireless remote monitoring is needed because it combines MEMS tilt sensing, 4G digital output, and battery power.Q: What does JMQJ-7915ATS measure?
A: It measures multi-point inclination inside a borehole using a vertical in-place inclinometer string and an orifice acquisition module.Q: Can tilt data be used with other sensors?
A: Yes. It is often reviewed with settlement, displacement, strain, load, water level, rainfall, vibration, and inspection records.
Reviews
James Thompson
The tiltmeters and accelerometers are very sensitive and provide precise data. Perfect for our structural health monitoring system.
Michael Anderson
The strain gauges and load cells are extremely accurate and stable. They performed very well in our bridge monitoring project. Highly recommended!
