Expertise & Performance Spectrum

Performance Spectrum

The instruments and software packages described in this section refer essentially to our own products. Because, as turnkey providers, we wish to offer our clients one-stop service, we also provide other manufacturers’ products, which are not described hereinafter. We therefore also provide the associated services, data acquisition and evaluation software for third-party products.

Special systems, which fall directly under the technical areas Underground & Mining, Surface & Structures or Industry can be found under the corresponding menu points.

Automatic 3D and distance measuring systems

To monitor objects and site areas at risk, measurements are performed via motorised total stations to signalling measuring points via prisms. To cover larger areas, arbitrary numbers of total stations can together be linked into one system. Laser systems for on-line distance measurements are also...

Levelling systems

Apart from classical levelling, there are also systems suited for on-line data acquisition. This can be implemented using rotating lasers and active sensors in areas where the measuring points are in line of sight with a central point. Inside buildings, hydrostatic measuring systems (liquid...

Reflectors and marking material

As specialists in the surveying of underground and engineering structures, the focus of our products lies in these areas. Especially our reflector programme and the necessary ancillaries for the highly accurate optical 3D displacement measurement distinguishes itself by its high manufacturing...

Extensometers and axial borehole displacements / joint and crack displacements

Extensometers are used to measure axial deformation in a borehole. They measure the relative displacement between one or more fixed points in a borehole and a measuring station at the entrance to the borehole. There are also various types of probe extensometers that can handle a higher number of...
Details

Inclinometers and tilt sensors

Tilt sensors are used in inclinometers to measure lateral displacements in boreholes. The measurements can be carried out manually, using a probe which is moved along a borehole step by step, or via a chain of several stationary transducers along the length of the borehole. Uniaxial or biaxial tilt...

Strain meters and pressure cells

Strain gauges are often used in tunnel construction and to measure the stress in the shotcrete lining. Since shotcrete, as opposed to concrete, can absorb significantly higher deformations, it is advisable to use strain gauges with DMS technology (because of the higher measuring range compared to...

Anchor load Cells and measuring anchors

Hydraulic load plates with manometer readings or electrical pressure transducers are available for measuring anchor forces.

Measuring anchors work along the same principles as extensometers, except that the anchor points are not free to move, but are mounted in a hollow bolt. The strain in the...

Piezometers and water level sensors

There are numerous methods for measuring the water level in boreholes and for water pressure measurement. These range from simple measurements in open standpipes by means of a cable and light plumb, via various systems using piezometers, to the measurement of joint water pressures. This chapter...

Temperature measurements

Temperature measurements are generally a component of systems for measuring parameters which are affected by temperature. The results of temperature measurements are used for compensation.

Vibration and noise measurements

GEODATA does not produce own instruments in this sector, but can offer the supply of systems by renowned manufacturers and performance of the measurements. Based on many years of experience in this field, we are a competent partner in all areas of application, from single measurements up to...
Details

Data acquisition

Complementary to data capturing instruments for on-site acquisition of the values measured by the instruments, GEODATA also offers an automatic data acquisition system. The measuring results of all suitable instruments, irrespective of the type of sensor and the physical measurement...
Details

Surveying software

Ever since GEODATA started its work in the geodesic field, it also worked on developing its own software solutions. The technical competence and experience of the responsible staff resulted in special solutions for underground applications, which are unique in respect of completeness and...
Details

Geotechnical evaluation software

Specialised evaluation and visualisation software is available for the most common geotechnical instruments. This software caters fully for instruments used most frequently in the main cross-section of tunnel construction. In this way, measuring results can be displayed quickly and clearly. When...
