Pratt & Whitney Measurement Systems, Inc. Electrolimit Comparator

The Pratt & Whitney Electro limit® Comparator offers the same resolution and accuracy as our laser-based instruments, but at a fraction of the cost. When compared with other electronic and mechanical comparators, the dynamic range (ratio of range/accuracy) of 2000 for our comparator far exceeds that of other comparators, typically replacing the full comparator indicator product line of other manufacturers. The Electro limit Comparator is the ultimate comparator for measuring flat, cylindrical, and spherical objects. A configurable general purpose anvil (optional) provides point contact support for measuring the three geometry types. Point contact ensures high accuracy and speed by eliminating the variability and time associated with surface and line contact geometry. The Electro limit Comparator stand is a dual rod design that is considerably stiffer than other single rod designs. The vertical slider employs kinematic contact to ensure minimal position change when locking the slider. Once the slider is locked in position, the comparator has frictionless motion and zero free play. A vertical flexure lift provides clearance for inserting and retracting parts, while maintaining sub millionth repeatability. The Electro limit Comparator stand stiffness ensures repeatable measurements typically not achieved with other comparator stands.
