Most engineers are familiar with the importance of regular checks on diesel engine crankshafts and cylinder liner. The old dial gauge for crankshaft alignment checks was time-consuming, unpleasant, dirty and gave uncertain accuracy. By using Prisma Tibro’s electronic Deflection Indicator DI-5 series, the task will be much more comfortable, and the accuracy will be improved. As an option to the instrument, you can connect the ovality kit to check the cylinder liner ovality and wear comparison. The Deflection Indicator DI-5 series has been used by large numbers of engineers in over 90 countries worldwide.

Four push buttons on the DI-5C panel are used to select, change and accept values on the display such as temperature, engine number, number of cylinders, measurement direction, and so on. Just push the OK button to store the value. On completion of the first cylinder, move the transducer to the next cylinder and store measurement values. The generous measurement range allows the transducer to be moved between cylinders without mechanical adjustment. When all cylinders are completed soft copy can be downloaded to a PC for reference and future comparisons.
