It is possible that the sensor was installed correctly, but the sensor ID wasn’t changed or wasn’t input correctly in the client application. Try entering the sensor ID again and wait for transmissions. If you have access to a laptop with the TyreSense client application, you can also use Sensor Tracker to detect all transmitting sensors within range of the receiver unit used. Look for a sensor with the correct pressure and a sensor ID that is similar to the one written on the shop installation record or entered in the client application.
Yes. There is a contrast setting in the user options. Refer to the In-Cab Display Unit User Guide for more information.
This might be a hardware installation issue instead, depending where the RF antenna is mounted. Reposition the antenna, check all the connections, and see if data for more sensors appears. Also refer to the TyreSense Troubleshooting Guide for more information.
You can use the Sensor Buddy tool to detect sensor IDs. Refer to the Sensor Buddy User Guide. You can also use Sensor Tracker in the client application and induce the sensor with a magnet. For the TS4 client application, refer to the Sensor Tracker topic in the online help system.
The cold pressure value is the pressure value adjusted to 20 °C (68 °F). That value is calculated using the tire’s pressure, and temperature according to the Ideal Gas Law. This information is available from the tire manufacturer.
You can use the Correlation Calculator tool to help you calculate appropriate gauge pressure values in different ambient temperatures.
We recommend using the magmount to install wheel sensors. If your application still requires a patch mount, the sensor patch MUST be prepped, glued and dry properly. Failure to do so will result in an improper bond to the inside of the tire. A sensor patch installation guide is available under User Guides. All steps are fully documented and must be followed EXACTLY.
The RF transmissions from the wheel sensors may not be getting to the receiver unit. For example, some loss of signal is expected for a stationary truck where a sensor is oriented on the opposite side of a rim; the signal from that sensor may not be received. In the case of generally weak RF transmission, however, an external high-gain antenna may be required. Contact Support for more information.
The rising and falling gauge pressure phenomenon we see within a tire is a result of changing temperature, according to the Ideal Gas Law, stating that pressure is proportional to temperature. As the temperature increases, there will be a rise in pressure. The cold pressure line is compensated for temperature, however, and should remain flat. Furthermore, on a TyreSense datalog for a fully sealed tire, there should be pressure fluctuations within 1 PSI, proving that the temperature measurements and pressure correlation is exact. If the cold pressure line changes, this could indicate an over pressure or under pressure situation.
The cold pressure line should be flat in a graph or datalog for a sealed tire. If a graph or datalog shows a decline in the cold pressure over time, this indicates there is probably a leak. A tire losing 1 PSI of pressure per day might not be detected by daily pressure checks for several weeks, however, changes in the cold pressure values in a vehicle’s datalog can help crews identify leaks more quickly. Also, the system can be configured to send alert notifications when a cold inflation pressure threshold is reached.
