Digital Angle Indicators

These angle indicators display highly accurate angle, level, and tilt measurements. They come set at true 0°, but you can choose an alternate zero point with the push of a button. Another button will freeze the reading on the display. Indicators have machined leveling surfaces, a V-groove for stability on curved surfaces, and two 6-32 threaded holes for mounting.
Angle indicator with an RS-232 computer connection can be used for ASCII output.

Proximity-Sensor Shaft Alignment Kits

Align rotary shafts with the help of a mobile app. These sensor kits are more accurate than straightedges and easier to use than dial indicators. Properly aligning shafts reduces vibration and protects couplings, bearings, and other parts from wear and damage.
Use the included chain clamps to mount these sensors above your coupling, where they detect the degree of misalignment between the shafts. The app shows live animations to give step-by-step instructions for repositioning your equipment. Once the shafts are aligned, the app saves a report documenting the process.
Good for extended use in industrial environments, these sensors last up to 18 hours between charges and are IP54 rated for protection from dust.
