Linear and rotary measurement

October 2008 Maintenance, Test & Measurement, Calibration

With the LIMES LI20 and LI50 Kübler is offering a new generation of measuring heads in a solid die-cast housing. Used in conjunction with its magnetic bands with their stainless-steel covering, the resulting linear measurement system stays sealed even in harsh industrial environments and offers security against failures in the field. The magnetic rings offer the user a remarkably compact measurement system for rotary applications where installation space is very tight. Installation depths of only 16 mm are possible with a large hollow shaft of 30 mm.

The non-contact technology ensures high vibration and shock resistance. The products can also be used outdoors, thanks to the high IP67 protection rating, the permitted 100% humidity with condensation, the wide temperature range and the weatherproof die-cast housing. The metal housing also offers improved shielding against electromagnetic interference.

Installation is easy due to the large alignment tolerances, up to 1 mm for LI20 and 2 mm for LI50, which apply not only to the distance from band to sensor head but also for lateral misalignment. A built-in LED, which gives a red warning signal if the distance from the band to the reading head is too great or if the speed is too high, also assists with the mounting. A green light shows the index pulse. The wide supply voltage range from 5 to 30 V d.c. likewise facilitates installation. The connections are made via a high-grade shielded PUR cable that is also suitable for trailing cable applications.

The sensing head is available either with a push-pull output or an RS422 interface and supplies two channels plus a periodic index with the corresponding inverted channels. The resolution is up to 5 microns with quadruple evaluation and the repeat accuracy is +/- one increment. The maximum traversing speed is 25 m/s.
