Industrial TPMS manufacturer · sensors, receivers, cloud
Industrial TPMS for heavy-duty vehicles and equipment
Every tire on every machine, one system
We are an industrial TPMS manufacturer: we design and build the entire chain in-house — sensors, receivers, repeaters, displays, CAN Bus DTUs and the 4G cloud platform. Connect your system to CAN, J1939, RS485, PROFINET, RS232 or Modbus, or use the DTU to put the whole fleet online with no custom wiring.
TPMS for the tyres. Telematics for the machine.
224wheels on a single vehicle
10,000+motorcycle units / month
1,000+municipal buses per year
2,000+wireless gateways installed

Who we build TPMS for
We supply either turnkey systems or the sensing hardware on its own. Most of our work is behind someone else's brand.
Mining operators
Rigid and articulated haul trucks, wheel loaders, high-temperature duty.
Port machinery builders
RTG cranes, reach stackers, container handlers and stackers.
Fleet operators
Depot-level monitoring across buses, trucks and trailers.
Vehicle OEMs
Commercial vehicle platforms that need tire data on the vehicle bus.
System integrators
Documented protocol for your own controller, PLC or VCU.
TPMS distributors
Private-label kits and regional distribution programmes.
Industrial IoT companies
Battery-powered sensing nodes with 4G backhaul and an open API.
Solutions
Start from the problem, not the part number
Most TPMS projects fail at the interface, not at the sensor. Tell us which controller has to receive the data and we build the chain around it.
Integration
Wire into the machine's own controller
An integrated receiver with CAN / J1939, RS485, Modbus RTU, Profinet or RS232 output. The controller reads tire data like any other node — no second display, no separate system.
Networking
Put a dispersed fleet on one dashboard
The same receiver plus a 4G DTU becomes a connected unit reporting to a cloud dashboard: fleet overview, alarms, history per vehicle, and an open API into your own platform.
Multi-axle
Watch every wheel on very long vehicles
Up to 256 wheel positions on one vehicle with repeaters along the chassis. Delivered on a 160-wheel beam carrier; the largest machine we have instrumented carries 224 wheels.
Products
Industrial TPMS, in five configurations
One 433.92 MHz sensor platform, five ways to get the data where it is needed — from a standalone cab display to raw CAN-bus output for your own platform.
A · up to 256 tires
Large standalone display
7" colour LCD, every tire at a glance, Bar/PSI and °C/°F switchable. Delivered on a 224-tire installation.
C · CAN / RS232 / RS485
Integrated module
No display of its own — feeds tire data into your CAN bus, PLC, VCU or host display. Documented protocol for second development.
D · 4G CAT.1 + GPS
Cloud version with GPS
Live tire data in an App or PC platform, plus vehicle tracking, route history and anti-theft. Up to 42 tires per unit.
Also supplied as components
Beyond turnkey systems we supply sensing hardware on its own — for dashboard makers, integrators and IoT programmes that build their own product around it.
Light vehicle · BLE sensor
BPU100 motorcycle BLE sensor
BLE 5.1 pressure and temperature sensor for motorcycle and light-vehicle dashboards. Pairs straight to CarPlay head units; CR1632 replaceable without re-pairing.

IoT · battery sensing
Universal IoT sensor platform
Battery-powered sensing nodes with 4G Cat.1 backhaul and an open API — door, temperature, humidity and vibration variants.

Applications
Built for machines that cannot afford a flat tire
Slow leaks, under-inflation and overheating cost more than tires — they cost uptime. Our systems watch every wheel and report where your operators already look.
- Port machinery — RTG, reach stacker, container stacker
- Mining & construction — rigid and articulated dump trucks, wheel loaders
- Multi-axle heavy transport — beam carriers up to 224 wheels
- Public transit & airport — buses and aircraft tractors
Where our systems run
Pick the duty that matches your machines, or go straight to the machines themselves.

Technical resources
How tire data actually gets into a controller, and what we learn doing it.
TPMS for Agricultural Machinery: Why Farm Tyres Need It
A farm tyre runs on a hard road and in soft soil the same day, and the right pressure is not the same for both. Agricultural machinery is where that difference is largest - and where the site usually has no mobile network to fall back on.
J1939 TPMS: What 29-bit Extended Frame Means
"29-bit is not a marketing detail. It decides which filters your controller needs, whether your tool sees the frames, and where the mapping work lands."
Why we don't ask for your CAN protocol
The sentence that stops telematics projects is "we need your CAN protocol". Here is why we never ask, what we ask for instead, and four ways customers use it.
Tell us your vehicle and we will size the system
Send the wheel count, operating voltage and which controller should receive the data. We reply with a wiring plan, a sensor count and a quote.
Frequently asked questions
What does an industrial TPMS manufacturer actually supply?
Not just sensors. A working chain from the valve stem to the screen or the vehicle bus: sensors, receivers, repeaters, displays, gateways and the cloud platform — plus the protocol documentation your engineers need to integrate it.
How many tires can one TPMS receiver support?
Up to 256 wheel positions per receiver. Beyond that, or on very long chassis where the radio path is blocked, we add repeaters along the machine — a 160-wheel beam carrier uses 2 receivers and 12 repeaters.
Can the TPMS connect to a vehicle CAN bus or J1939 network?
Yes. The receiver publishes tire pressure, temperature and alarm data onto CAN 2.0B, and we supply the message map (DBC) so your controller, PLC or VCU can read it like any other node. J1939, RS485, RS232, Modbus RTU and PROFINET are also available.
Do you supply TPMS for mining trucks and port machinery?
That is our core market. We have instrumented rigid and articulated haul trucks, RTG cranes, reach stackers, container stackers and beam carriers, and we supply port machinery builders under their own brand.
How many wheels can you monitor on a single vehicle?
The largest machine we have instrumented carries 224 wheels (28 axles × 8). The next size down in production is a 160-wheel bridge girder transporter.
Can you build TPMS to our specification as an OEM or ODM programme?
Yes — that is most of what we do. Protocol, enclosure, display UI, cloud API, packaging and label language can all be adapted. Certification is scoped per target market as part of the programme.
What is the operating temperature and protection rating?
Internal sensors −40 to +125 °C, external sensors −20 to +85 °C, IP68, 433.92 MHz licence-free radio, accuracy ±7 kPa (433.92 MHz) on pressure and ±3 °C on temperature.
Do you provide sample units before a production order?
Yes. We start with evaluation units and the pairing or protocol documentation so your technical contact can test against your own devices, then move to a pilot order.
