Ovality Sensor

The Ovality Sensor is a measurement tool for rotary kilns, which measures the changes of the roundness / curvature in the kiln shell during operation. This elastic deformation is called Ovality and is primarily present in the area of a kiln tire. The measurement gives accurate information about the degree of mechanical loads in the refractory / kiln shell and allows defining the countermeasures in advance to increase the lifetime of the kiln components. The Ovality Sensor is small, easy to use and comes along with a tough transport case.

Measuring Principle

The Ovality Sensor consists of a Deflection Plate, which will be attached with heat resistant magnets to the kiln shell close to a tire. Due to the strong magnetic connection, the deflection in the Deflection Plate follows the deflection of the kiln shell below. Strain gauges are measuring the deflection in the Deflection Plate. The electronic converter is amplifying and conditioning the signals from the strain gauges and sending them together with the values of the angle position sensor via Bluetooth connection to a laptop. The software TomTom-Tools Measurement Studio (for Windows), which comes together with the measurement tool is made to receive, store and process the values from the Ovality Sensor. During the measurement, the values are displayed and calculated directly in real time. There are different display, zoom and report printing options available.
