Telematica axle load monitor system

Choose the right sensor for your suspension

Telematica air suspension axle load sensor
Air suspension

Wireless axle load sensor for air suspension

Measures the air pressure in the suspension to work out axle load, giving you live readings that help prevent overloading, improve fuel efficiency and keep you within provincial weight limits.

Real-time load monitoring. Accurate load weight from suspension air pressure
Wireless transmission. Sends data over Bluetooth to your tracker, the platform and the mobile app
Long battery life. Up to five years on a built-in battery, with no external power needed
Easy installation. Fits straight into the air suspension with no complicated wiring
Tamper-proof and durable. Wireless design avoids cable damage and vandalism
Self-diagnostics. Continuously checks its own performance for reliable readings

Recommended for: trucks and trailers with air suspension, heavy-duty freight fleets, and fleet managers wanting maintenance-free load monitoring.

Telematica leaf spring axle load sensor
Leaf spring

Wireless axle load sensor for leaf spring suspension

Measures how far the vehicle frame moves relative to the axle to calculate load on leaf spring suspensions. It helps prevent overloading, reduces wear and tear and supports compliance.

Load from frame displacement. Detects how much the frame moves under different loads
Wireless connectivity. Sends readings to your tracker, the platform and the mobile app
Five-year battery. Works independently with no external power connection
No wiring required. Simple, non-intrusive installation on the axle
Automatic load tracking. Alerts managers to load changes and unauthorised cargo handling
Tamper-resistant. Durable wireless design that handles rough terrain

Recommended for: trucks and trailers with leaf spring suspension.

FAQ

Axle load monitor FAQs

How does a wireless axle load monitor work?
Air suspension sensors read the suspension air pressure, and leaf spring sensors measure frame movement. Both convert the reading to axle load and send it over Bluetooth.
Does it need wiring?
No. Sensors run on a built-in battery that lasts up to five years and connect wirelessly.
Can drivers see axle weights?
Yes. Drivers can check live readings in the mobile app before they leave the yard.
Will it help avoid overweight fines?
Real-time axle load data helps drivers and managers spot overloading before the truck reaches the scale. Weight limits vary by province, so check the limits that apply to your routes.
Does it work with Telematica GPS tracking?
Yes. Axle load readings sit alongside location and trip data in the Telematica platform.
Is an axle load monitor the same as on-board weighing?
Yes. Axle load monitors are a form of on-board weighing that shows estimated axle group weights in real time, helping you avoid overloading.
How much does an axle load monitor cost?
Pricing depends on the number of axle groups and whether your suspension is air or leaf spring. Request a quote for your trucks and trailers.
