cut32 LongRange runs a slim, self-adhesive sensing tape alongside the cable you need to protect. The moment the tape is severed, the alarm goes out over LTE — and seconds later the system names the exact section of the run, on a map, on your engineers' phones.
The control box powers and continuously interrogates a dual-track conductive sensing tape laid along the protected cable. The run is divided into nodes — passive, maintenance-free sections with no electronics, no power and nothing to service in the field. A terminator closes the far end of the loop.
A dedicated measurement processor interrogates the tape continuously through a surge-protected analog front end, combining three complementary techniques — so the system doesn't just see that something happened, it can say what happened and where.
A calibrated current source and 16-bit precision converter track the loop's resistance against its commissioning baseline. A degrading joint shows up as drift — flagged for maintenance long before it fails. And because the tape has a known resistance per metre, anything bridging the two tracks reads out directly as a distance.
Every node boundary carries a precision capacitive marker. After a cut, the control box measures the line's total capacitance and simply counts the markers still reachable — the count names the severed node. Fully passive along the whole run: nothing out there needs power, batteries or maintenance, ever.
The measurement engine resolves events to roughly a nanosecond, timing signal edges and charge ramps directly in hardware. It underpins the capacitance locator, timestamps the attack forensics — and supports time-domain reflectometry on high-conductivity tape variants for installations that demand it.
Different events yield different information — so rather than one vague headline figure, here is exactly what LongRange tells you, for each thing that can happen to the line.
| Event | How it's measured | Detection | Location |
|---|---|---|---|
| Cable cut tape fully severed |
Loop opens instantly; capacitive node count then names the last reachable node. | <1 ms on-box alarm sent immediately over LTE |
±1 node node length is yours to choose: 1–50 m per section |
| Cutting attempt / short blade or object bridging the tracks |
Precision resistance reads the distance directly — the tape's resistance per metre turns ohms into metres. | <1 ms on-box plus full waveform capture |
<0.5 m at 1 km metre-class on runs to 10 km |
| Degrading joint corrosion, strain, water ingress |
Scheduled resistance trending against the commissioning baseline, reported to the platform. | Hourly trend flagged before it becomes a failure |
Predictive maintenance visit, not a 3 a.m. alarm |
| Power or comms loss at the control box |
Internal battery keeps the box guarding and reporting; the platform independently alerts if the box goes dark. | Supervised both directions, continuously |
GPS position of the control box itself |
Every customer gets a private, secure tenant on the cut32 platform — your own branded hostname, your devices, your people, fully isolated from everyone else's.
Live status of every run, alarm history, health trends, user management and alert routing — under your own name.cut32.com hostname.
Alerts tailored to each engineer's area and responsibilities. A cut drops a pin on the map, names the node, and guides the engineer to the exact section — plus a simple interface for repair and commissioning.
At install, each node is QR-scanned in sequence with a phone — capturing identity, order and GPS position in one action. The platform then verifies the measured node count against the scans before the installer leaves site.
No trenching crews, no field cabinets, no powered equipment along the run. The tape bonds flat with its permanent self-adhesive backing; everything active lives in one control box.
Run the slim, self-adhesive sensing tape along the cable, tray, duct or wall it protects. Node boundaries go wherever suits the site — every 1 to 50 metres — setting the location resolution you'll get.
At each node, scan its QR label with the installer app. One scan captures the node's identity, its order along the run and its GPS position — building the live map as you walk the route.
The control box measures the finished line and the platform confirms it can see exactly the nodes you scanned — a bad joint or a missed scan is flagged on site, not discovered at 3 a.m.
