lineGrip lineScale 2
An electronic 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.
This dynamometer is a resurrection of our slackPro lineScale… fully reworked, optimized and equipped with new technology (lithium battery, bluetooth, app, etc.).

Hurry, theres only a few left of the first batch. Once these are sold out, new stock will be available in April 2020!
Thank you to all supporters
The pre-series sample passed all tests with flying colors and the first 100 units are almost ready for shipping :-)A huge "thank you" to all the crowdfunding supporters for making this possible. Without you we would not have been able to realize this project!Join the lineScale project group: www.facebook.com/groups/lineScale.2.project/Benefit from the pre-order discount (available for another 2-3 weeks): www.linegrip.com/shop/linescale-2-pre-order/Cheers- the lineGrip teamGepostet von LineGrip Corp.

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!
The lineScale works by the priciple of material micro deformation: Wikipedia – Strain Gauge
A threshold load value can be set 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.
The lineScale 2, with its 80kN MBS, is perfectly suited as a bomber, generously dimensioned, nicely organized anchor master point – also known as “rigging plate” – for your highline rig.
The large omnidirectional, cross-load proof eyelets are chamfered with a 4mm radius and can easily accommodate 6-8 strands of 10mm rope from your equalizing anchors, which makes multi connector management an ease.
The 24-bit high definition AD-converter with dual strain gauge configuration has a resolution of 1kg with a measuring error of less than ±0.5% (inside the “sweet spot” area of 300kg – 1500kg / 3kN – 15kN, which is 10-50% of WLL.

An integrated Bluetooth-4 interface connects the lineScale to your smartphone for configuration, and load value reading and recording.
Apps for iOS and Android devices are included with the lineScale.

The powerful 1000mAh Li-Ion battery pack gives the lineScale-2 an endurance of up to 50 hours continuous operation (ca. 24h with Bluetooth enabled and in “fast” scan mode).
If no load change is registered for the preset shutoff interval, the device will auto power off. It was essential for us to assure, that the scale does NOT calibrate its sensors to 0 when powered on, but immediately shows the current load. This enables you to power off and on manually anytime when you need a load reading. This makes your scale go for weeks without having to recharge.
If power does run low, you may recharge at any time during operation (e.g. with a powerbank).

The sensor scan rate (cycle rate) is 40Hz, meaning the lineScale reads and calculates the sensor load every 25ms, which makes it sensitive for fairly short peak loads. Any load peaks shorter than 25ms may be missed by the sensors, however this is very, very unlikely for slackline use.
To save energy you may toggle the lineScale to “slow” scan rate (10Hz / 100ms) which is sufficient for simple load tension monitoring for slackline rigging.
