lineGrip lineScale 2

A digital bluetooth dyno / dynamometer / load cell specifically designed for measuring slackline tension up to 30kN (3 tons). The huge load eyes and 80kN breaking strength make it perfectly suited as a rigging plate / master point for highlines.

lineGrip lineScale-2 Batch2 dyno load cell

This dynamometer is a resurrection of our slackPro lineScale from 2014… fully reworked, optimized and equipped with up to date technology (lithium battery, bluetooth, app, etc.). This batch-2 model comes in an awesome copper-gold color 😀

Development, production, and finally getting all the little details right, took us almost one year (350 days to be exact).

But the wait, patience, and persistence was well worth the while… this baby is truly perfection in every aspect!

On Monday Dec. 2nd 2019 at 1600 CET 98 lineScales are finally ready to be shipped to their owners.

Materials

Material bodyaviation aluminum alloy LY12CZ
Coloringanodized in brilliant copper-gold color
Manufacturing technologymilled from solid block
Assembly Methodadhesive sealed

Safety is Paramount

This device is milled out of one solid block of high-tensile aviation aluminum (LY12CZ), giving it a whopping 80kN MBS. In terms of safety this is the best deal you can get. Theres no bolts, screws, rings, pistons or joints that could possibly fail… this is the security of mind you need when leaving the scale in the highline rig while walking it! Independent break testing resulted in a mind blowing 110kN! (see below)

Working Principle

The lineScale works by the priciple of material micro deformation: Wikipedia – Strain Gauge

User Configurable

A threshold load value can be set in the Android and iOS app to sound an alarm when reached.
The displayed unit (kg, lb, kN) and the auto power off time can easily be selected and saved as preset by the user.
