The Talyrond 50 instrument is equipped with a rotating spindle with an oil-hydrostatic bearing. Whilst the TR 50 maintains a high level of measurement accuracy and performance reliability, it represents only a minimum of capital investment.

The optimal measuring speed is 3 rpm. A faster speed would reduce the transmission characteristics of the measurement chain. In this model the column is operated manually operated and allows work pieces of up to 250 mm in height to be measured.

SeRound the Software Retrofit for Talyrond50 is accurate, user friendly, robust and is performance driven. It is developed in-House at Salbro Engineers and provides a through interactive user interface between the user and the Instrument with the help of the Electronic Interface unit also developed in-House at Salbro Engineers

All Integrated to make one precise instrument to detect the following Roundness, Concentricity, Eccentricity, Relative Eccentricity, Flatness (3D Display). Squareness, Coaxiality and Run-out.

Data acquisition, profile filtering, evaluation of the roundness parameters and graphical output of the results as well as for the instrument control (like Starting and Stopping the motor and selection of the amplifier range) has been realized by SeRound.

The cycle of measure guides the operator in the operations of table centering and leveling and subsequently in the acquisition of the profile. Besides the default cycles of measure it is also possible to make calculations on the previously acquired profiles; moreover it is possible to plan the cycle of acquisitions. This is very useful especially when you have to measure many similar work pieces, with the same parameters and you need to enhance the measuring speed.
SeRound allows you to choose the method of calculation to perform the measurement and to elaborate the results. For the Roundness: circumference of the minimum squares, circumference of minimum zone, minimum circumscribed circumference, maximum subscribed circumference. For the Flatness: plan of the minimum squares, plan of the minimum zone, minimum superior plan and maximum inferior plan. One can even omit unwanted data not required to be analyzed.

SeRound’s Setup and Measure window provides a tool to the user to center the jobs quite accurately and quickly thus saving on time and improving productivity. 

TR 50 with SeRound Analysis software comes with 12 months warranty period
