The Model 4420 Crackmeter is intended to measure movement across surface cracks and joints. It is installed by grouting, bolting, or bonding two threaded anchors (with ball joints) on opposite sides of the crack and then attaching the ends of the gage to the anchors.
The Model GK-604D Digital Inclinometer System is delivered in its entirety and includes a Model 6100D Digital Inclinometer Probe, a reel-mounted cable and a Field PC. The Model 6100D contains electronics to convert the analog voltage into a digital signal, which is transmitted by the control cable to the cable reel containing the Interface, which communicates via Bluetooth® to the Model FPC-2 Field PC. A Digital Compass is built into the Inclinometer Probe to correct the inclinometer data sets for any twist (or spiraling) in the inclinometer casings. The spiral survey data is presented on (and stored in) the same FPC-2 Field PC used for taking inclinometer readings. An optional 12 volt electric cable reel system is available, which can provide substantial time savings when surveying deep inclinometer casings.
The Model 4000 Strain Gage is designed primarily for arc welding to steel structures such as tunnel linings, excavation bracing, piles and bridges. The gage has a 150 mm gage length (longer or shorter versions are also available), a 3000 µε range and a 1 µε sensitivity. The gage can be adapted for bonding to concrete or for bolting to steel surfaces by modification of the end blocks.
The Model 6161 MEMS Tilt Sensors are designed for attachment to structures, on either a vertical or horizontal surface, and for the subsequent measurement of any tilting that may occur. The sensor itself is a MEMS (Micro-Electro-Mechanical Systems) sensor, which offers a high range, with high sensitivity and accuracy. The included associated signal conditioning yields an output of ±4 V at ±15° and is designed to drive long cables without degradation. (Also see the Model 8003 (LC-3) Series MEMS Dataloggers.)
The Leica Nova MS60 MultiStation is the world’s first self-learning MultiStation, automatically and continuously adapting to any environment, despite any challenges.
Scanning with the Leica Nova MS60 has been made simpler through the instant creation of point clouds with overlaid measured points and 3D models in one view. Visualisations are clearer and easier to see on an all-new 5” screen. The unique capabilities of the Leica Nova MultiStation truly deliver the new experience in measuring technology.
The Model 3400 Semiconductor Piezometers and Pressure Transducers are intended for dynamic measurements of fluid and/or pore water pressures in standpipes, boreholes, embankments, pipelines, pressure vessels, reservoirs, etc. They are also used for static pressure movement where the readout system is incompatible with vibrating wire type transducers. Three transducer output options are available.
