Internal Sensor

You need Internal Sensors for accurate measurement of both pressure AND temperature of the OTR tire. This is critical in applications where tires are highly stressed, such as Mining and Earth Moving.

Each Sensor also transmits an estimate of the battery status. So as to aid identification, each Sensor has a unique four-digit identity code (ID) as part of the transmission. Additionally we laser-mark the ID on the body of each sensor.

Each Sensor periodically and under certain conditions broadcasts its ID and measurements as a radio transmission. The Hub then picks up these transmissions.

In order to assure accuracy, we calibrate all sensors across multiple points of the operating range as part of the production and test process. Accuracy is typically within 2psi across this range during our in-house test. Of course calibration certificates can be provided on request.

All equipment is designed and manufactured in-house at our facilities in the UK.

Internal Sensor mounting

You can mount the Sensor on the side wall of the tire (patch mounting) or use Magnetic Mounts on the rim.

Patch mounting

Affixing the Sensor to the side wall is a simple process using our proprietary TMS^® rubber toggle system. It glues onto the side wall of the tire, attaching to an industry standard tire patch. The patches themselves are flexible and lightweight and make a very secure mounting. This mounting can handle the natural flexing of the tire.

Magnetic Mounting

Alternatively, you can mount the Sensor on flexible magnetic mounts on the tire rim. The extremely powerful neodymium magnets combined with rubber toggles snap solidly to the surface of the steel rim inside the inflation chamber of the OTR tire. The integral rubber toggles handle any vehicle vibration. After installing the first bead during tire fitting, the magnets hold the sensor in place.
