LineScale 2

Electronic Bluetooth dynamometer specifically designed for slackline use – version 2 of the well known lineScale. 30kN WLL, about the size of a large hand, 20mm thin, only 495g light, and anodized in brilliant gold color! Generous D-Shape chamfered, cross-load proof attachment eyes to accept almost any conceivable connection type. Comes with rechargeable battery (via Micro-USB), bluetooth connectivity, smartphone app and protective felt pouch.

lineScale 2

Safety aspect

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!

Versatility

The lineScale 2, with its 80kN MBS, is perfectly suited as a bomber, generously dimensioned, nicely organized anchor/distribution point for your highline rig. The large omnidirectional, cross-load proof eyelets can easily accommodate 6-8 strands of 10mm rope from your equalizing anchors, which makes multi connector management an ease.

Working principle

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

User configuration

The displayed unit (kg, lb,kN) and the auto power off time can easily be selected and saved as preset by the user.

High Tech Power Management

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 on and off manually anytime when you need a load reading. This saves an enormous amount of power and makes your scale go for months without having to recharge.
Of course the device has a low battery warning indicator, but additionally it also displays the voltage reading of the battery pack when powering on, so you can recharge in time. The lineScale also has a low power emergency operation mode that ensures your batteries are not drained without you noticing. When power is in the critical range it will automatically power off after 3 minutes in any case to save power.

Accuracy

The 24Bit pro AD-Converter with dual strain gauge configuration has a resolution of 1kg with a measuring error of less than ±1% (only inside the sweet spot area of 300kg 1500kg / 3kN 15kN, which is 10-50% of maximum load). Please note: Below the sweet spot area the measuring error might be up to 15%, especially under 100kg this device is NOT a precision micro scale! See Limitations tab for further details.

Scan Rate

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. We promise to aim for the lowest possible scan rate within our budget.
Any peak load shorter than 25ms may be missed by the sensors, however this is very, very unlikely for slackline use. See Limitations tab for further details.

30kN WLL, about the size of a large hand, 20mm thin, and 495g light.
For highest possible safety, the lineScale unibody is milled from a solid block of high-strength aviation aluminum, which results in 80kN breaking strength. The generous D-Shape chamfered attachment eyes are cross-load proof and will accept almost any conceivable connector such as steel shackles, biners, industrial slings, ropes, webbing and soft-shackles.
Bluetooth connectivity allows you to display/log the load values on your smartphone and set a custom load alarm threshold via the lineScale-App.
It comes with a light, perfectly fitting protective felt pouch.

WARNING!

This device is NOT a professional analytical device or laboratory/research qualified dynamometer on which to base a single 100% reliability calculation of an unredundant life support system! The lineScale scans the load every 25ms, which might lead to the fact, that an ultra short peak load is missed, such as may occur when doing anchor bolt testing with short slings in factor 2 falls, for instance. It may also lead to slightly reduced reading of a leash fall in a very short highline, because the 25ms reading interval might have occured a few milliseconds before or after the peak load.
