Customers can achieve even better accuracy with Honeywell’s SMART Position Sensor, Rotary Configuration, if they control two occurrences in their application’s assembled system. The first controllable factor is tolerance stackup. What is tolerance stackup, and why is it important? Tolerance stack-up is the accumulation of errors that, in and of themselves, may be extremely small. Examples of these types of errors include slightly out-of-round shafts, minor eccentric component rotations, loose linkages, and other variations. When a designer starts having actuation and points that need to fit, each of those individual parts has a tolerance assigned to it. As these parts start to get out of alignment, the errors add up, greatly reducing sensor accuracy and causing unsatisfactory performance. The illustration on this slide helps to visually explain tolerance stackup, showing how eight separate measurements that equal 8.027 inches are larger than one measurement alone that equals 8.000 inches. As Honeywell’s SMART Position Sensor, Rotary Configuration, is a non-contact device, effectively only one measurement occurs. When the number of linkages is reduced, tolerance stackup will also be reduced.
