TMS® Hub – Airlink
The TMS® Hub is a small unit which is mounted in the vehicle and is the heart of the TPMS. It receives and decodes data from the internal and external sensors. This information includes sensor ID, pressure, temperature, and battery status.
Specifically designed for use on Industrial and Off-the-Road (OTR) vehicles, the Hub has four antenna inputs. Then the antennas connect to four independent receiver channels.
This unique design gives best in class communication sensitivity to ensure the most resilient signal reception possible. Consequently, the Hub will remain in communication with the Sensors even on the largest of vehicles with up to 24 wheels.
Signal reception remains nonstop even over large distances to the wheels. Neither electrical noise nor vast amounts of metalwork will interrupt the signal.
Data Tracking & Analysis
The sensors send the data to the hub. The hub securely logs and time-stamps the data in flash memory. It can store up to 1.4 million events before needing to download. Even with a huge amount of stored data, it downloads quickly to the TMS® App.
Any readings outside pre-defined levels prompt an alert to the driver or fleet manager. Each wheel can have its own defined alerts for low and high pressure, high temperature, low battery, and no data.
In addition to these alerts, there is a system to monitor if one wheel is running hotter than the others. The temperature difference is user defined.

Additional ports are available so you can connect the hub to your own equipment. Hence you can extract all the crucial data to manage the tire pressure and temperatures on the whole fleet.
Additionally, a full Application Programming Interface (API) is available free of charge to our partners. This links the real-time data from our sensors to your own software or platform.
The Hub continually monitors atmospheric pressure. This means it shows readings in true gauge pressure.
Installation is simple using the pre-wired cables supplied. These cables link the Operator Interface (Display) and the vehicle’s power supply.
The Hub replaces our legacy receiver.

Airlink
The Airlink (TMS38) is an optional extra that adds WiFi and Bluetooth connectivity to the Hub. This is achieved by plugging this small antenna device into the Hub and mounting it near the window/dashboard of the vehicle.
This simple, low-cost addition allows the Hub to be connected to the customer’s WiFi or indeed the Wifi that is often included within the vehicle. Once linked through the WiFi, all the tire data is available on the cloud from wherever you are in the world. This data can be viewed using the TMS-Remote web portal or the TMS-Cloud App.
The Bluetooth connection is Bluetooth Low Energy and means operators don’t need to plug into the Hub – they can simply connect up from their Android Smart phone, tablet or PC. This feature makes it a simple job to view all tire data from the TMS® App as you walk around the vehicle

The Airlink can be simultaneously connected to two Bluetooth connections and a WiFi connection. The six LEDs on the front give a comprehensive range of diagnostic information to confirm what is connected and that data is flowing as expected.
