There are two types of Direct Tire Pressure Monitoring Systems – 1) internal sensor systems where the sensor is inside the tire or 2) external systems which use external sensors Internal systems use sensors that are strapped around the wheel or replace the valve stem and are inside the tire. Internal sensor systems require additional antennas in the wheel wells for reliable reception of sensor signals, are expensive to install and maintain and are challenged with getting a reliable signal through the metal and materials of a tire. External systems are those which have sensors which read from outside of the tire with Tirebull the leader in this market, easier to install, maintain and use. Following, is a comparison of Internal (vs.) External Systems.
· INTERNAL SENSOR SYSTEMS:
o More expensive for equipment and to install, require added time for installation.
o Normally require extra antennas in each wheel well which can be broken or damaged.
o Have difficulty getting a clean signal out of the tire which is essentially a metal cage.
o Sensors are easily damaged when removing a tire from the rim.
o Do not give a pressure reading until vehicle is moving at least 20mph.
o Give a low pressure alert only when the tire is 20% to 25% low on pressure.
o Sensors make it difficult to rotate tires. The sensors have to be removed to reprogram, or you must purchase expensive electronic tools to reset the sensor to the monitor.
o Expensive to maintain, taking time and money to break down the tires to get to them.
o Can’t be used with tubed tires that use the bladder in the tire to hold air.
o Can be easily damaged when removing the tire, by excess heat common inside of tires (can be caused by several things, a stuck brake, a wheel bearing, hard braking).
o Internal systems are not as reliable or as accurate as Tirebull
In truck fleets worldwide, fleets have consistently turned away from internal sensors because of the time and expense it takes to break down all tires to install, to maintain and to replace when necessary. Inside the tire sensors are not able to acquire pressure readings until the vehicle is moving which means the vehicle will leave its ‘yard’ before they know there is a problem. The driver now has to stop, turn around, and go back for repairs. Fleets are inconvenienced and suffer loses due to the much higher alert levels of internal sensor systems. Internal sensors alert to low pressure only after pressures have a 20% to 25% loss. The tire and casing are already damaged, you have more wear on the tire and you’ve reduced fuel and time efficiency.
2) EXTERNAL SENSOR SYSTEMS:
· Less expensive, quick and easy to install, simple to use.
· Do not require antennas in each wheel well.
· Sensors are durable using specially designed GE materials.
· Sensors are not inside a metal container, reliable strong, clear signal for greater reliability.
· Tirebull alerts to low pressure and displays current pressures while parked or on the move.
· Tirebull has two alert levels – 12.5% and 25% low – giving drivers a warning and allowing them determine how severe the problem is and how quickly they must take action to be safe.
· External sensor systems are simple to install, take little time to replace and low cost to maintain.
· Tirebull is one of the most experienced and oldest TPMS products in the market, the original external sensor system.
· Tirebullsensors can be re-programmed to new positions or switched to new vehicles easily, quickly and without hassles or any breakdown of tires.
· Tirebullis durable, accurate and reliable.
Tirebull offers more features than any system on the market and is one of the very few to offer compatibility to GPS/Asset Tracking type products. Tirebull offers a higher degree of tire protection by alerting at lower pressure loss situations and displaying current pressures and alerts - while parked or on the move.
Tirebull is the market leader because it works; it’s reliable, durable and accurate. Tirebull is easy to install and simple to use. Tirebull compared against all other TPMS systems products, offers the most cost competitive pricing and the most reliable in the TPMS market. Tirebullis a leader in reliability, durability and accuracy with an easy to install and simple to use system. Frost & Sullivan, well respected in the U.S. and worldwide, found Tirebull be the best Tire Pressure Monitoring System, adding savings and safety for fleets with all types of vehicles.
