A company overviewInquiries
Bartec USA have a range of TPMS Test Antennas and Tools designed for different stages of the wheel and tire assembly line. These are designed to read the Tire Pressure sensors to show they are working at key stages of the assembly process and to also to test and prove that a fully tested wheel and tire assembly with TPMS is transferred to the final line.
The systems have been supplied to many wheel and tire businesses around the world including: MC Syncro, Goodyear, T&WA, Superior Wheel, Great Lakes, Topy, TWISThink, Accuride, Prime Wheel, AAP St Marys, Hayes Lemerrz, ION, Schedl, FSZM and the internal wheel and tire assembly lines of most of the OEM's.
Almost all TPMS types operate at similar frequencies enabling a common process in the plant test environment.
These systems provide the following advantages:
The TPMS can be externally excited using a 125KHz Low Frequency signal and they respond with a UHF signal at either 315MHz or 433MHz.
The Bartec USA equipment ensures that the right LF datagram signals are used to activate the TPMS at the correct power level, and that the corresponding decoding is used to obtain the information from the TPMS. The reading equipment can be configured to read any TPMS and be integrated into an existing plant seamlessly.
There are 3 main types of TPM sensor mounting arrangement to the wheel rim.
Schrader based TPM electronics with a pull through fitting which needs no special equipment to install other than a standard rubber stem puller.
Most popular type of fitting adopted by most manufacturers. Usually requires a dynamic programmable torque wrench or torque profiling gun to mount. Additionally, may also require a mounting jig to assist with the installation and ensure the parts are fitted at the correct angle and a good seal is formed without breakage. Some manufacturers specify a particular torque profile and torquing process be applied to ensure a good residual torque.
Only used by Ford and now superseded however, still original fitment on many US manufactured Ford vehicles. The TPMS sits on the rim centre and is opposite the valve stem, held in place with a steel band.
The most common method of testing TPMS fitted wheel and tire assemblies is to use an automated TPMS Test system on the assembly line after the TPMS has been fitted to the wheel. This process will test for any TPMS that is fitted over the entire area of the wheel face (as shown on the right in the image).
The typical process is:
This process tests that the TPMS is still operational and (depending on where the test is performed relative to the other line operations) it is possible to check the pressure is within set limits.
All data can be stored indefinitely for future traceability of every wheel through the test system giving confidence that all assemblies are 100% functional.
Bartec USA use very technically advanced software and electronics in each antenna and controller to achieve the most reliable and aggressive reading process.
Our latest antenna, IAS (Integrated Antenna System) has multiple receivers, software downloadable TPMS types, easy setup and configuration and supports all current known TPMS types.
The Bartec USA equipment is well placed to support any future models of TPMS variant also. Every antenna is tested and mapped at our facility to ensure that a consistent LF field is presented each and every time ensuring a high quality read rate.
It is advisable to locate the position of a TPMS in the wheel before the tire is fitted to ensure the sensor is not damaged during the mounting process. Damage occurs if the tire bead contacts the sensor as it is being stretched over the wheel rim.
If this option is required then Bartec USA have a special ORIENT antenna.
This antenna is designed to activate the TPMS in only a specific 'pie section' of the overall wheel diameter. The testing function of the TPMS, once activated in the correct section, is the same as for the DETECT systems. All data can be logged and an audit created.
If the Tire Pressure sensor is not within the defined area then the unit test will fail alerting the plant systems so that the Tire Pressure sensor can be protected from damage at subsequent stations – usually by either repositioning (line stop) or by being taken off the line.
This can be done by a live OBD connection from the TPMS PC via a carrier to an OBD over the vehicle line or by a TPMS hand tool with OBD connectivity and programme function.
Bartec USA are able to control the field of these types of antenna such that the desired ‘pie section’ is achieved.
These are very advanced systems and rely on our understanding of the TPMS characteristics to provide a solution to very challenging requirements. As with the DETECT systems, these use the IAS antenna providing the best reading solution and the best future proofing options.
