The 3rd generation LineScale is a giant leap forward, not only for LineScale, but for the entire “all-in-one” dynamometers. It is FAST: 1280Hz, SAFE: 10kN PPE rated, and SMART: comes with memory to store logs on-board.

Fast enough to capture dynamic tests, and with PPE certification suitable for professionals in industry and rope access. This opens up entire new markets compared to the predecessor LS2, and any other available dyno.

Safety aspect
This device is milled out of one solid block of high-tensile aviation aluminum (LY12CZ), giving it a whopping 90kN 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 rigging while under load! And because it is so safe, we have it PPE rated so even industrial professionals can use it in their everyday work.

Certifications
Electronics: Certified for RF regulations:
BQB BLE 4.2/5.0, EN CE ETSI RED, FCC, IC(Canada); FCC ID: 2ADXE-HY-40R204PC
Safety: PPE industry standard RfU EN PPE-R/11.114 V2, UIAA safety label, and CE mark.

Versatility
The lineScale-3, with its 90kN MBS, is perfectly suited as a bomber, generously dimensioned, nicely organized anchor/distribution point for your rigging or rope-access 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 priciple
The lineScale works by the priciple 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. You can also define at which speed the logs will be stored to onboard memory (capacity for 2 million data points), which gives you 50 hours of log time @ 10 Hz and 25 minutes of log time @ 1280 Hz.

Operation Modes
The LineScale-3 has two operation modes:
1. NET mode, which always shows the true, real load, independent of any potentially set zero (or tare) points.
2. ZERO mode, which shows the offset from the defined “zero” (or tare) load value.

High Tech Power Management
The LineScale will auto power off if no load change is registered for the preset shutoff interval. It was essential for us to assure that the scale does NOT calibrate its sensors to 0 when powered on. Instead it immediately shows the current true load (when in NET mode). 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.

Additionally the LS3i is equipped with a “display off” function, which blanks the OLED display after a defined time to extend battery life to the max. while the LineScale is running all jobs in the background. Onboard logging, Bluetooth connections, etc. are not interrupted and you can check the display anytime by the press of any button.

The LS3i 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 ±0.5% (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 2%, especially under 100kg… this device is NOT a precision micro scale!

Scan Rate
The sensor scan rate (cycle rate) is 10Hz for power save BT mode, and 40Hz for high BT mode. The max. scan rate is 1280Hz, and data save mode 640Hz for USB connection or the onboard memory logging.

Onboard memory logging
The lineScale-3i is equipped with onboard memory to log over 200 million data points. Depending on the selected scan rate, this is sufficient for 25 minutes to 50 hours of log time.

The system will automatically over write the oldest log, which ensures fulltime 100% logging of all load events as long as the lineScale is on and loaded.
Onboard logs can be downloaded via USB.

The LS3i features a few minor refinements from the LS3, such as:
– solid reverse side (no more inserted plate)
– slightly larger front label (but same OLED)
– less torsion and bending sensitivity
– less temperature sensitivity (almost perfect temp. compensation)
– better IP rating (IP68-0.1m instead of IP67)
(the specs, electronics, OLED display, etc. remain the same)
