NOVATEST CX-3C - Инклинометр

The CX-3C removable borehole inclinometer is a high-precision inclination detection system, designed for geotechnical and structural monitoring.‎ It is particularly suitable for geological monitoring, construction, civil engineering, and other similar safety monitoring applications.‎ Main Product Features: MODBUS RTU protocol compliant Wide measuring range High precision Stable performance Solid and durable Easy maintenance TECHNICAL FEATURES Technical Specifications: Number of Axes: 2 axes Measuring Range: ±15° (±30° option available) Cable: 60 m with a diameter of 8.‎40 mm Output: RS485 (Modbus RTU protocol) Power Supply: Voltage 8～30V DC Repeatability: ±0.‎003° Accuracy: 0.‎001° – 0.‎005° Sensor Technology: MEMS IP Protection Class: IP68 Probe Dimensions: 28 mm x 790 mm (diameter * length) External Dimensions: 310 x 400 x 200 mm Operating and Storage Temperatures: from -20 to +60°C Continuous Working Time: 10 hours Typical Applications: Geotechnical and structural monitoring (Geo/Structural Monitoring) Reference Standards: GB50026-2007 / ISO18674-3-2017 ACCESSORIES Wellhead Top Support: A mechanical device installed at the top of the borehole or guide casing.‎ It serves as a stable reference point and support for the correct insertion and positioning of the inclinometer probe and cable.‎ Its function is to ensure precise and repeatable insertion of the probe, protect the guide casing mouth, and facilitate measurement operations.‎ Data Logger: An app installed on a Smartphone for collecting, storing, and transmitting inclination data measured by the probe.‎ It includes an interface for connection to the sensor and for transferring data to a computer or remote monitoring system.‎ Its function is to acquire and record inclination readings from the probe for subsequent analysis.‎ Guides: Spring-loaded mechanical components mounted on the body of the inclinometer probe.‎ They are designed to slide within the longitudinal grooves of the guide casing installed in the ground or structure.‎ Their function is to ensure that the probe maintains a constant and precise orientation during descent and ascent in the guide casing, allowing for accurate and repeatable measurements along the entire borehole profile.‎ Cable: A robust, graduated cable used to lower and raise the inclinometer probe inside the guide casing.‎ In addition to supporting the probe’s weight, it integrates electrical conductors for powering the probe and transmitting data to the reading unit.‎ It allows positioning of the probe at specific depths and provides the electrical connection for data transmission.‎ Inclinometer Probe: The heart of the system.‎ It is a cylinder containing MEMS sensors capable of measuring inclination on two orthogonal axes with respect to the vertical.‎ It is equipped with guide wheels for insertion into the casing.‎ It measures angular deviations (inclinations) at different depths along the borehole profile, allowing for the determination of lateral displacement of the monitored ground or structure.‎ Universal Joint: A flexible mechanical joint that connects segments of the probe or the probe itself to the cable or other components.‎ It allows for a certain angular flexibility between the connected parts.‎ This facilitates navigation of the probe through any minor curvatures or misalignments in the guide casing and reduces mechanical stress on connectors and the probe itself.‎ Data Acquisition and Analysis Software: An app on a mobile device to download, display, process, and interpret the collected data.‎ It can also function as a handheld device that connects directly to the probe or cable to display real-time readings and store them.‎ Carrying Case: A robust case designed to protect the probe, data logger, and other components during transport and storage.‎ User Manual Optional Accessories: Connection Tube/Extension: Segments of tube, usually of the same length as the probe or standard lengths (e.‎g.‎, 1m, 2m, 3m), used to extend the overall length of the probe system in a fixed “in-place” installation, or to connect multiple probes in series.‎ This allows monitoring at different predefined depths in a fixed system, or adapts the probe length to specific measurement needs.‎ Guide Casing/Inclinometer Casing: A special tube, typically made of PVC, aluminum, or fiberglass, permanently installed in the ground, in a concrete structure, or in an embankment.‎ It has internal longitudinal grooves (usually four, at 90° to each other) that guide the probe wheels.‎ Its function is to provide stable access and a guided path for the inclinometer probe, ensuring that measurements are always taken in the same orientation and position along the vertical profile.‎ Extension Cables and Connectors: Used to extend the range of the reading cable or for specific connections.‎     Further info from manufacturer on CX-3C NOVATEST
