 Download this page in Microsoft Word FormatINFORMATION TO COMPLETE THE SHAFT DATA FORMS SI, MD, TQ, and AL The forms provide the data that Indikon requires to design the applicable shaft instrumentation system Form SI - System Information Form MD - Mechanical Data Form TQ - Data for Torque System Form AL - Data for Alignment System (Forms SI and MD are required on all systems but, depending on the type of system being ordered, if you checked torquemeter only - fill Form TQ - if Alignment was checked then fill Form AL, and if you checked Torquemeter and Alignment then completing both, Forms TQ and AL will be required.) ADDITIONAL INFORMATION RELATING TO THE FORMS As the end user of the product may be different than the original specifier/customer, the information provided will assist in correlating future requests for spare parts and service by using 'job number' should the need arise. While certain information may appear to be unnecessary, it is useful in achieving an optimum design. Example, the degree of shaft misalignment must be known for a Torque system in order to provide adequate clearances between the Indikon rotor and stator components. The correct environmental classification is necessary for each of the units so that they can be designed for the conditions in the locations where they will be used. For example, in the case of the I/O unit, it assures that the correct enclosure is selected. When any of the units are in a hazardous environment, intrinsic safety barriers and/or power supplies are generally required. Indikon Torque and Hot Alignment Systems are typically composed of a coupling, a local input/output instrument and a 'readout'. Describe location of system (if possible provide drawing) showing all the details and interconnecting cable lengths. In general, the functional range of the system, its readout ranges, the range of its analog outputs, and the point at which it is calibrated, should be consistent with the actual operating regimen. While manufacturers usually define the ratings of the coupling on their drawings, these do not necessarily represent the actual operating conditions for the machine. In the case of a Torquemeter, a point should be defined as '100 percent torque'; this torque is then considered to be the 'full scale' of the system. The torquemeter is designed to provide a linear output up to approximately 125 percent of this 'full scale' value. While the calibration point is usually at 'full scale', it may be at some other value if required. Indikon will suggest appropriate values for the analog output and digital readouts for confirmation by customer. For an Alignment system, the normal operating point may be at only a fraction of its operating range, which may exist under certain conditions, so a much wider operating range may be desirable. A wider range will enable the alignment of the machine to be observed even under abnormal conditions or during a cold start. The Alignment system can usually be designed to give an accurate indication up to the capabilities of the flexible coupling itself. Calibration is performed at a fixed value of approximately 7 mill radians (1 mill radian = 1 mil/inch or 1 micron/millimeter). |
