Before choosing

Choose the right TPMS sensor for your truck

Not all pressure sensors are compatible with the same valves, working ranges or applications. Before choosing a sensor, consider:

  • Truck or trailer type.
  • Number of tires.
  • Operating pressure.
  • Valve type and diameter.
  • Wheel accessibility.
  • Inner or outer position.
  • Compatibility with the TPMS monitor.
  • Working conditions.
  • Need for additional durability.
  • Distance between the sensors and the monitor.

An incorrect selection can complicate installation, prevent inflation, limit communication with the monitor or apply a pressure range unsuited to the unit.

  • Large tires.
  • Heavy machinery.
  • Equipment with large bore valves.
  • Units with high working pressure.
  • Special transportation applications.

Confirm before requesting a quote

  • Valve type.

How it works

How does a truck TPMS sensor work?

A TPMS sensor measures tire conditions and transmits the information to a compatible monitor.

  1. The sensor is installed on the valve

    The mounting type depends on the sensor, the valve and the wheel configuration.

  2. It records pressure

    The sensor detects the tire air pressure and sends the reading to the monitor.

  3. It monitors temperature

    Compatible sensors also record temperature to identify abnormal changes during operation.

  4. It transmits the information

    The signal is sent wirelessly to the TPMS monitor installed in the cab or to the receiving component of the system.

  5. The system identifies each position

    Each sensor is configured to match a specific position on the truck, semi-truck or trailer.

  6. Alerts are generated

    The monitor warns when pressure or temperature exceeds the configured parameters.

What do pressure sensors monitor?

Low pressure
The system can alert when a tire falls below the level defined for the operation.
High pressure
Pressure above the established parameter may also require review.
Rapid air loss
The sensor can help identify a sudden drop that requires stopping and checking the unit.
High temperature
An abnormal increase may be related to low pressure, friction, brakes, bearings or another mechanical condition.
Individual position
Each sensor is linked to a position so the operator can identify which tire needs attention.

Sensors do not diagnose the mechanical cause of an alert on their own. The condition must be confirmed through a physical inspection.

By configuration

TPMS sensors for your fleet

Sensor selection depends on operating pressure, valve type and monitor model.

Light and medium trucks

They usually require external sensors for configurations of up to 6 wheels.

Semi-trucks

They require one sensor per position (e.g. 10 sensors for 10 tires), plus the monitor and the necessary accessories.

Trailers and semi-trailers

Because of distance and metal structures, a signal booster may be required to ensure communication with the monitor in the cab.

Dual wheels

Ensuring access to the valves is essential; metal valves, extensions, adapters or T-type valves can be used.

Do you need one sensor, a kit or the complete system?

Every fleet has unique requirements, so we offer flexible, tailored options that match exactly what your units need:

Replacement sensors

Ideal if you need to replace a damaged or lost sensor in a system that is already running.

Sensor kits

Packages designed to configure the exact number of sensors for each unit type (truck, semi-truck or trailer).

Complete TPMS systems

The end-to-end option including monitor, sensors, T-valves and accessories, ideal to start monitoring from scratch.

We focus on personalized support, reviewing the technical specifications of your equipment — valve type, monitor model and operating conditions — to recommend exactly the configuration your fleet requires.

Benefits

Benefits of monitoring every tire with TPMS sensors

From detection to protection

Detect a pressure loss

The sensor lets you observe changes during the trip, not only when the unit is parked.

Identify the affected position

The monitor indicates which tire shows a condition outside the established range.

Act on an alert before a failure

The information allows checking the unit before the air loss causes greater damage.

Protect tire service life

Operating with incorrect pressure can cause irregular wear, heat build-up and casing damage.

Benefits that grow with the operation

Complement inspections

Sensors provide continuous information, while the physical inspection confirms the condition of the tire, valve, rim and mechanical components.

Monitor trailers

A properly configured system can include positions on both the semi-truck and the trailer.

Expand an existing system

When the monitor has available capacity, compatible sensors can be added for more positions.

Continuous monitoring supports faster decisions while physical inspection confirms the actual condition of the tire.
