What Is A Pressure Monitoring System? And How Does It Work?

A tire Pressure Monitoring System, also known as PMS, is an electronic device designed to precisely monitor the tires’ pressure on different kinds of vehicles. PMS monitors the tire Pressure automatically and informs the driver about the status of tire pressure. A good PMS report tells the driver about the current tire pressure, optimum air pressure, and the range of tension in the tires.

A good PMS uses a simple indicator light with multiple modes to indicate the different tire pressure levels. A high-pressure warning light flashes while the pressure is above average, and a low-pressure warning light flashes when the pressure is below average. It has an automatic off switch, which can be manually set to off. A wheel speed indicator, which varies according to traveling speed, reminds the operator when the tires are not running according to normal conditions. An auto shut-off mechanism is also there to stop the machine if the pressure goes beyond a predetermined safe limit. The automobile speed sensor monitors the speed in case of a rise in the rate of the tires.

Automatic Tire Pressure Monitoring Systems
Automatic tire Pressure monitoring systems are generally used on small trucks, cars, and some boats. There are industrial vehicles that may require installing a computerized system to keep the tires in shape. Sometimes an auto pump is installed along with the auto tire Pressure sensors for cars that run on gasoline. These sensors are widely used to detect low pressure in the tires.
The auto-tire pressure monitoring systems monitor tires’ pressure and warn the owner when the pressure is too low. Pressure-sensitive gauge needles appear on the dashboard and alert the owner of low tire pressure. When the hands go low, this indicates that the car’s safety belt has been improperly worn or broken. Some warning lights also flash, and one or more warning lights flash while the pressure sensor is used.

Sometimes the warning lights blink or flash when the tires are overfilled. Low tire pressure causes the indicator light to flash and one or more warning lights to flash. Some vehicles may have additional indicators, including a trip meter, engine oil pressure gauge, battery voltage meter, and fuel level indicator light. These instruments are located near the rearview mirror on most cars. Sometimes the warning light on the dashboard fender indicates the low tire pressure.

Pressure monitors measure the inflation pressure of tires and alert the driver by flashing the warning light. Some sensors determine the minimum and maximum levels of tread depth and inflation pressure. The minimum tread sensors and the full inflation pressure sensors are located on the inside of the tire. The next sensor is located outside the tire on the tread block.

There Are Types Of Tires
Different types of tires may require various sensors for achieving the proper pressure. Most vehicles will typically have four tires, and any other additional tires may need additional sensors. The different sensors are used primarily to assist with the automobile’s anti-lock brake system. However, some cars come with the ability to control and maintain the car’s tires from a remote location.
The technology used to operate these instruments dates back to the 1960s. The first pressure gauges that were used contained tiny versions of a pressure measuring device. Today, the tools are sophisticated and include an LCD screen and a host of temperature and pressure sensors. Additional components are available to support the instrument cluster as part of an automobile’s instrument panel.


The automobile’s tire pressure sensor is located between the tire pressure help and the wheel speed sensors. These two components play a vital role in maintaining the proper levels of tire pressure. An electric motor powers the help center while the engine controls the speed sensor. The help center is usually located beside the engine so that it is readily seen. Its signal is then transmitted to the tire pressure to help display the tire pressure readings in real-time.
The tire pressure help also contains a built-in safety indication light that should be illuminated when the pressure levels are too low.

Some cars and trucks have a separate gauge within the vehicle that displays the tire pressure and low tire pressure warnings. Other cars and trucks have the two indicator lights on the gauge cluster itself. When the tire pressure is displayed as low as one or two percent, this is a warning that something is wrong.

The light also turns red when the car is moving at speeds over ten miles per hour or when the temperature inside the vehicle reaches around seventy degrees Fahrenheit. If either of these conditions is experienced, the car is pulled over immediately for further inspection.
Most modern vehicles come with a digital gauge. It is a smaller version of the traditional pressure gauge that is found in fleet vehicles. In most cases, it is located near the driver’s seat in a place that is unobtrusive. It displays the regular tire pressure readings along with any advanced warning symbols like tire pressure flash.

And How Does It Work?
A tire pressure monitoring system is a computerized system that employs stem sensors to record the air pressure in individual tires on various types of automobiles, ranging from full-size long-haul trucks to small passenger cars such as SUVs or minivans.

The pressure Monitoring System, also known as PMS, has two main components:

Computerized Pressure Monitoring System (CPMS) and the Portable Pressure Monitoring System (PPMS).

The Computerized Pressure Monitoring System (CPMS) is installed in a truck or tractor during the maintenance period and provides the truck’s owner with detailed information about tire pressure. The CPMS is linked to a computer via a cable or a bus that communicates data to the monitor, displaying the tire pressure status and other related data.

On vintage vehicles such as vans and cars, tire-pressure sensors are usually mounted on the inside of the front fender near the tire valve. However, modern vehicles come with built-in pressure monitoring systems installed directly in the engine compartment. This sensor is usually incorporated in the oil pump, relays the data to a small LCD screen to record and store information.

LCD screen

The small LCD screen is used for various purposes, including recording maximum tire pressure, tire condition, and other performance-related activities. Some vehicle owners use this tool to monitor and control the car’s engine speed. If you consider purchasing a CPMS for your vehicle, there are certain essential factors that you need to keep in mind to get the best product. The monitor should have all the required features and should be manufactured by renowned manufacturing companies such as O’Flynn, Bosch, Fruehauf, etc.

These manufacturers use the most advanced technology to ensure that the sensors included in these products are accurate and provide optimum performance. Some of these high-performance sensors can distinguish between any positive and negative pressure.

For example, an air pressure gauge with a positive reading can be immediately reset to zero if a vehicle loses pressure over a specific limit. Moreover, an auto spare tire pressure monitor should also have the ability to detect changes in airflow, temperature, and humidity along with the air pressure. It enables the device to calculate the exact amount of air needed for proper tire performance.

There Are Some Advantages
Besides the advantages mentioned above, these high-performance vehicle sensors are pretty sensitive and can maintain accurate readings even when vehicle engines run at low speeds. They measure the air pressure as well as the wheel speed sensors accurately. Moreover, they provide maximum accuracy and are low maintenance. The best thing about these vehicle sensors is that they can sense vehicle speed even when the engine is off. It ensures that tires are correctly maintained during off-road adventures.

A vehicle’s tire pressure is calculated by measuring the force required to push the weight load against the tire’s rim. This force is referred to as tire-to-rim force. This force is proportional to the wheel’s rotation speed. The pressure Monitoring System helps in determining the correct pressure. However, various other factors affect pressure, such as:

One of the main advantages of these high-performance tire pressure monitors is that they are designed to sense low tire pressure even when the engine is running. Such low tire pressure sensors have an advantage over those that depend on engine pressure. These sensors not only detect low tire pressure but can also indicate other engine conditions such as oil pressure, idle speed, exhaust gas level, and much more.

Furthermore, these high-performance tire sensors can switch to low gear automatically if necessary to help avoid sudden outgassing. They have been tested for over ten years and are equipped with the latest technology that ensures minimal battery drain and minimum signal drop.

All vehicles in today’s era have built-in tire pressure gauges. However, there are instances where these gauge systems are damaged or destroyed. So, how do you keep your tire pressures in good condition without spending a lot of money to repair or replace them?
