Pacific Industrial, who began operation as a manufacturer of automobile valve core, developed the TPMS transmitter as value-added next generation valve using its unique technologies cultivated over many years.

Our TPMS transmitter is “direct style”, attached to the inside of the tire so its sensor can detect pressure or temperature irregularities in the tire, and send the information to the receiver by wireless. As each country has its own Radio Law to meet the local frequency, we have developed a different transmitter model for each country.

As the device is attached to the inside of the tire, special design is required to withstand vibration, wide temperature range, high humidity conditions, and chemicals inside the tire. Configuration design, wireless transmission, and environment resistance are all taken into account to develop the TPMS transmitter into a smaller, lighter, and more functional transmitter.
