Inclinometers
Inclinometer System
The HMA Geotechnical Model 7000 Digital Inclinometer System measures the lateral deflection of installed HMA Model 7040 and 7060 inclinometer casing.
The complete system consists of: Digital MEMS Probe (0.5 m Wheelbase), Cable Reel with Bluetooth (Cable lengths available (m): 30, 50, 100, 200, 300, others at request), Readout Unit (Android Tablet), Case & Accessories.
85mm Inclinometer Casing
HMA Geotechnical Model 7060 Inclinometer Casing is designed to be installed in environments in which subsurface monitoring is to take place, to provide access for either an inclinometer system or ShapeArray. The Model 7060 (Green) casing is used over the Model 7040 (Yellow) casing where a greater shear capacity is required. The casing features self-aligning and has self-coupling connections, and can be rapidly installed on-site with little effort.
ShapeArray
Model 7300 ShapeArray (SAAV/SAAX) is a new alternative to Model 7200 in-place inclinometers and Model 7000 traversing inclinometers. ShapeArray is an automated inclination measuring instrument, capable of being installed vertically, horizontally, or in an arc. It has been installed across many mines and civil projects in Australia, providing high-quality data for the end user.
Submersible Tilt Meter
The RST Submersible Tiltmeter provides precision real-time remote monitoring of tilt of submerged structures. It consists of a MEMS inclinometer sensor and electronics mounted inside a rugged waterproof enclosure. The instrument housing is machined from solid stainless steel, providing extreme endurance for long-term high-pressure underwater service. The cable entry is a submarine grade connector, which provides watertight performance at depths exceeding 200 meters.
In-Place Inclinometer New Generation
The HMA Geotechnical Model 7800 In-Place Inclinometer (IPI) is designed to provide real time lateral deflection monitoring without the manual labour aspect found with the use of the Model 7000 Digital Inclinometer. It consists of a string of MEMS sensors joined together by steel bay rods, allowing for a borehole profile to be measured.
Inclinometer Casing
HMA Geotechnical Model 7040 Inclinometer Casing is designed to be installed in environments in which subsurface monitoring is to take place, to provide access for either an inclinometer system or ShapeArray. The casing features self-aligning and self-coupling connections, and can be rapidly installed on-site with little effort.
The Model 7040 is kept in stock across many of HMA’s offices and can be quickly dispatched when required.
Tilt Sensor/Tilt Logger
Tiltmeters are designed to measure tilt in structures such as buildings, dams and embankments. They are usually mounted in-place horizontally or vertically and are connected to a data logger for measurements. Tiltmeters are available in Uniaxial or Biaxial configurations, with varying installation configurations such as submersible tilt meters and tilt meter beams.
Inclinometer Electric Winch
The HMA Geotechnical Model 7010 Inclinometer Winch has been designed to assist with the use of the Model 7000 Digital Inclinometer. The Inclinometer Winch allows for precision assisted retrieval of an inclinometer and cable (up to 300 metres long), and with the use of the supplied autostopper will automatically halt winch operation every 0.5 metres to allow for an inclinometer measurement. The Winch includes precision signal slip rings and a protective steel transport case.
Series 7000
The monitoring of slopes is generally carried out using an Inclinometer System which consists of an embedded consumable casing with keyways to guide a probe in a fixed axis. Boreholes are drilled parallel to the suspected falling plane and the casing grouted in place. Either a traversing probe or in-place probes are used to monitor deviation from original position. HMA Geotechnical use the RST Blue tooth probe system because of its light weight and technically advanced design. In place sensors are used if data logging of outputs is required.
