Dry running pump protection

Dry running pump protection

Bases of the new technology of IBJ Technology of an dry running protection for pumps (also: Pump protection) are new realizations for the propagation of surface waves. The characteristics of Rayleigh-waves are used in new sensors for applications in liquids and multi-phase mixtures. The new ultrasonic sensors are protected as utility model and the procedure are announced with the German patent office to the patent. The new technology differs from the well-known state of the art, like time of flight or pulses technology, by its independence from the transmission characteristics of the liquids. The well-known procedures for reason lying idea, the evaluation of flutter echoes in a gate far outside of tube sheet reflections and reflections in the sensor (diaphragm and own decaying), can be used both for measurement by the wall (no contact of the sensor with the medium), and for measurement with screwing in sensors in the tubing or container wall. However bad transmission characteristics of the liquid have an unfavorable effect. Against it if Rayleigh-waves to the attendance supervision or detection are used by liquid phases, are the transmission characteristics of the liquid without influence on the function of the sensors. Thus screwing in sensors for the Low cost range, and fastidious measurements can be realized by the wall at containers and aggregates. With screwing in sensors thereby an optimal signal transmission is guaranteed. The height of the transmission tension can be minimized therefore. Also with unfavorable reflectors (curved tube sheets, pump impellers etc.), which so not sufficient echoes causes, can therefore the presence of a liquid be determined. For all processes and applications, where the sensor contact with the medium does not disturb, thereby a simple pump protection is possible. The measurements by the wall adhering the lack of problematic start-up (couple conditions between sensor and tube sheet should be defined and as reproducible as possible) becomes groundless thereby. Particularly for solid-loaded liquids, salt solutions or suspensions generally, this technology is favourably applicable.

In January 2003 IBJ -Technology as partner of the industry for the interests of the process measuring technique one based.
Owner of the engineer's office for innovative measuring technique is
Mr. Dipl.-Ing. (TH), Dipl.-Ing.-Oek. Frank- Michael Jäger.
Our activity and thus our experiences in the process measuring technique for fastidious applications justify themselves on one over 15 years activity in the project management and development in research establishments of the chemistry, the natural gas industry and the mining industry.
The practical use of measurement principles and sensor technologies under most difficult operating conditions is supplemented by one over 12 years advisory activities to the employment and the use from process measuring technique to the benefit of the customers within all ranges of the economy.
As independent and reliable partners of the industry we offer comprehensive solutions in all questions of the process measuring technique.
Particularly with fastidious applications of the ultrasonic technology we can repair problems with new solutions.
Many innovative solutions for measuring tasks in the most different industries were protected in a multiplicity by patents and utility models.

.Smart Rock Stress Sensor with MEMS
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 •

Acousto elastic concrete strain sensors are used to detect the metrological Expansion or compression of steel building components as well as for measurements in reinforced and unreinforced concrete bodies used. The thickness of the susceptor (diameter of the bars) may be selected according to the strength reinforcement. The acousto elastic concrete strain sensors can also be mounted on the outside parts of the structure of steel. With flanges or angle mounting is
