Smart 2D rock stress sensor wih triaxial accelerometer and magnetometer

The RSS-X series of acousto elastic sensors from IBJ Techhnology is used to measure variations in compressive stress and load, which allows stress evaluation when the material’s modulus of elasticity is unknown or anisotropic and inhomogeneous. Typical examples are concretes and drill holes in the rocks, where these instruments can be used include:

• Mining
• Tunnel supports
• Deformations of pillars
• Dams and nuclear power plants
• Structural members of buildings and bridges
• Piles and caissons
• Movements and landslides

The sensor detects the compression of a metal body. This metal body is 2 components resin and protected housing. The housing is arranged in concrete or in the iron braid of reinforcement.
The compression are measured with ultrasonic pulse-echo method. In the case of concrete compressive stress sensor, an ultrasonic sensor is included.
The RSS-X is offered in two models, RSS-X and RSS-2X, that differ in their measured axis.
RSS-2 X two systems owned by 90 ° turned. The horizontal and vertical stress is measured.
The sensors with Triaxial accelerometer with mag-netometer (compass) or without can be equipped. Therefore, the alignment of the bore hole and the position of the sensor for crimping the expansion of cement can be determined.

The runtime in the measuring element is measured in high resolution with a separate stress meter. All ultrasound devices to the bolt measurement with a maximum frequency of 10 MHz is suitable for the measurement.
The term declines linearly with the compression in the elastic range.
Which the compressive stress sensor surrounding concrete is a compression of the measuring element. The change in the length of the measuring element is not only dependent on the load or stress, but also on the temperature.
Both factors taken into account the ultrasound measuring device for measuring the change in length.
A permanent temperature measurement is integrated into the pressure voltage sensor. This temperature sensor work as 1-wire sensor with ROM for the identification.
For universal use, the sensor for all devices for the measurement of bolt is suitable regardless of the manufacturer. The automatic temperature correction of these devices can be used, a second is incorporated independent temperature sensor.

The term due to the change in length and acousto elastical effect has reduced the influence of the surrounding concrete on the measuring element.

IBJ Technology as a partner of the industry for the interests of process measurement technology was founded in January 2003.

Owner of the Engineering Office for innovative measuring technology is Mr. Dipl.-Ing. (TH), Dipl.-Ing.oec. Frank-Michael Jaeger.

With the sensor BBS 10_DS from IBJ Technology, surface pressure in concrete components can be determined also afterwards. The applications range from the direct stress measurement in the component to the measurement and monitoring of dynamic loads in real time. Ultrasonic captures the stress in the structure directly and in real time. All changes can be transferred online via the Internet or satellite radio. The sensors are either placed directly in
Customized sensors for tensile stresses in the concrete
After the patent-pending process of IBJ Technology sensors for strain and compressive stresses can be manufactured in almost all imaginable sizes. The area includes a few inches to several 10 foot length. The diameter of the measuring element can be adjusted to the diameter of the reinforcement in the concrete. The sensor detects the strain or deformation of a metal rod. This metal rod can be arranged in the iron braid
