External Sensor Kit
External Sensors are used to measure tire pressure and temperature when speed and convenience are important. The external sensor means there is no need to remove the tire.
Temperature measurements are slightly less accurate than with Internal Sensors because the External Sensors are not mounted inside the tire.
The standard TMS® External Sensor kit includes everything you need for a 6-wheel configuration.
The Kit includes:
- 6 External Sensors
- T-pieces
- Cables
- Connectors
- A Quick Start Guide

Easy to install, the External Sensors screw directly onto the large bore tire valves.
There is no need to remove the valve system. An extra T-piece is also provided to allow manual checks and inflation without the need to remove the External Sensor.
The standard External Sensor kit includes the Operator Interface (Display).
But when the TMS® system links directly back to any Fleet Management Software, the Display is not a requirement.
If this is the case, we can easily change the kit to leave out the Display and its cables.
A site that is using the TMS® product for the first time will also need a separate Sensor Reader (TMS28). This is needed for setup and diagnostics.
The whole fleet only needs one or two of these. They are not part of the vehicle installation. As such they do not come as standard in the kit.
External Sensor Kit Application
We have supplied our TPMS for installation on a vast range of industrial and Off-the-Road (OTR) vehicles, including all major vehicle manufacturers such as.
- Caterpillar
- Komatsu
- Hitachi
- Bell
- Volvo
- Sandvik
- Belaz
- Liebherr
If you use a different Make or Model of vehicle, we can create a specific kit for that vehicle.
As independent manufacturers, we can supply tire pressure monitoring systems for any make and size of tire. This includes all of the popular makes such as Bridgestone, Michelin and Goodyear.
