// ZYGLOX SENSOR TECHNOLOGY

Maintenance costs 50% of a train's lifetime. Without data, you're flying blind.

Every day, hundreds of thousands of kilometers are driven by rail. We help you use each of them to learn, improve, and predict. Using conventional methods gathering this data has been too expensive, too slow, and too disruptive. 

We built a better way.

// WHY IT CHANGES EVERYTHING

OUR INNOVATION

// 01
Non-Invasive
Installed from outside

No structural modifications. No downtime. No taking the train off the tracks for weeks. Mount it externally and start collecting data within the same shift.

// 02
30 minutes
for installation

The alternative takes weeks, costs a fortune, and requires modification of your components. Zyglox sensors take 30 minutes to install and leave everything intact.

// 03
Live data
on bogie and rail condition

Every kilometer driven becomes a data point. Trend analysis, anomaly detection, real-time load monitoring — the foundation for condition-based maintenance and an expected 10–15% reduction in maintenance costs.

// THE PROBLEM WE SOLVE

THE CHALLENGE

Since 1938
the measurement technology hasn't changed

Strain gauges and instrumented wheel-sets require weeks of installation, structural modifications to your components, and break down under long-term field conditions.Great for short test windows. Not for continuous monitoring.

50%
of a train's lifecycle cost is maintenance. And most of it is managed blind.

The result of missing data: Over-engineered components. Maintenance runs on schedules, not on condition. Problems are discovered at the next inspection — not when they happen.

HOW IT WORKS

ZYGLOX TURNS THE AXLE INTO ITS OWN SENSOR

Mechanical stress changes the magnetic permeability of ferromagnetic materials. Our patented sensors detect these changes without contact — no modifications, no wear, no ongoing maintenance on the sensor itself.

The result is a perfectly linear, history-independent stress measurement that matches the precision of strain gauges, nstalled in 30 minutes, running continuously.

ACTIVE MAGNETOELASTIC MEASUREMENT

Unlike passive magnetostriction — which is non-linear, hysteresis-prone, and unreliable for safety-critical use. Zyglox uses active excitation. Zero hysteresis. Precision data on every rotation.

1.0 0.5 0 −0.5 −1.0 −60 −30 30 60 Mechanical Stress (MPa) Magnetic Field (T) ±0.4 MPa
Passive Magnetostriction HIGH HYSTERESIS

Signal depends on the metal's magnetic history. Non-linear. Unreliable for safety-critical measurement.

Zyglox Active Magnetostriction ZERO HYSTERESIS

Perfectly linear. History-independent. Precision matching DMS strain gauges.

// // WHAT YOU GET

WE deliver

10-15%
MAINTENANCE COST SAVED

Enable condition based maintenance. Schedule fewer inspections by safely extending maintenance intervals. Reduce over-engineering.

LIVE
Fault-detection

Detect anomalies when they occur — not weeks later at a scheduled check. Act on condition, not on calendar.

// OPERATIONAL ADVANTAGES

YOUR BENEFIT

GAPLESS MONTIORING

Continuous data from every equipped axle, across every rotation. No gaps between inspections. No oeprational blind spots.

Maximum Predictability

Know when a component is trending toward failure before it fails. Fewer surprises. Fewer unplanned stoppages.

Real-Time Fault Detection

Detect anomalies when they occur — not weeks later at a scheduled check. Act on condition, not on calendar.

// WHO BENEFITS

FOR WHOM

RAILWAY OPERATORS

Shift from time-based to condition-based maintenance. Fewer delays. Fewer unexpected failures. 

  • Extend inspection intervals based on actual load data

  • Make operational decisions with confidence

  • Reduce unplanned downtime

MANUFACTURERS

Know what your components actually experience in the field. Build the next generation with real data. And when something fails — know whether it's your component or the track.

  • Reduce warranty risk with continuous load records

  • Improve component design based on real-world stress data

  • Deliver more with less over-engineering

// PRODUCTS

OUR SYSTEMS

Continuous monitoring

Non-invasive monitoring for hollow shaft axles. Measures stress distribution in real time across every rotation. Permanently installed, continuously running.

Stationary Inspection

Quality assurance for press-fit connections. Detects hidden defects that conventional methods, including standard press-fit curves, miss entirely.

5 WHEELSETS. 1 HIDDEN DEFECT.

In a blind study, five wheelsets were examined with the Zyglox Stationary Inspection sensor. One was defective. The press-fit curve looked completely normal across all five. We found it.
