The FIM is used for continuous measurement of borehole axial deformations. Similar to the sliding micrometer and the Trivec, the FIM is based on the cone-sphere setting principle. Probe lengths from 1 to 5 m are available. In boreholes with measuring tubes for Sliding Deformeter, Sliding Micrometer or Trivec, sections can be equipped with ...

PremiumManufactured by Solexperts AGbased in SWITZERLAND
Joint extensometers are used for displacement measurements in structural joints and cracks. The change in distance perpendicular to the joint and the vertical and horizontal shear movements are determined by suitable arrangement and combination of joint extensometers. The sensors are linear potentiometers encapsulated in a stainless steel ...

Manufactured by Soil Instruments Ltd - part of Nova Metrix LLCbased in UNITED KINGDOM
The Rod Extensometer system accurately measures settlement and/or heave at single or multiple anchor points in a borehole relative to it’s reference head. The system employs up to eight rods, anchored along the axis of a borehole with a diameter from 50mm up to 200mm, terminating in the reference head at the borehole ...

based in NETHERLANDS
A fiber optic displacement sensor is used to measure travel range between where an object is and a reference position. A displacement sensor is used for all kinds of dimension measurements, for example and object's thickness, height, and width in addition to travel range. The sensor on the left is a spring-loaded linear displacement sensor. This displacement sensor has a range of 30mm and can be ...

Manufactured by Durham Geo Slope Indicator (DGSI) - part of Nova Metrix LLCbased in USA
The Rod Extensometer consists of anchors set at specified depths, rods inside protective tubing, and a reference head. Measurements are taken at the reference head by micrometer or by an electric sensor. Advantages: Can be automated, can be read remotely, works in any orientation, can measure multiple points. Limitations: Limited measurement ...
