Why do you need a Diesel Particulate Filter sensor?

A lot of people are probably confused about why they need to purchase some parts along with their DPFs. Well, one good reason is that, for a DPF filter to efficiently work to better your vehicles, then you need all the necessary parts for it. 

A DPF is not a one-task engine, but it also needs its other contributing parts as well. With that in mind, you already know how much each part work to make sure a DPF filter is playing its role for your vehicle. 

However, it is not easy to find a direct supplier to provide you with all of this. That’s where we help at DPFParts.com. We are a direct supplier for all your DPF needs— from gaskets to clamps, to pressure sensors. One of the best brands we have is the Mitsubishi Fuso diesel particulate filter sensor.

With that, let’s find out how a DPF sensor pressure works and why you need one.

In a nutshell, a pressure sensor converts the pressure to a small electrical signal that is transmitted and displayed. These are also commonly called pressure transmitters because of this. Two common signals that are used is a 4 to 20 milliamps signal and a 0 to 5 Volts signal.

Most pressure sensors work using the piezoelectric effect. This is when a material creates an electric charge in response to stress. This stress is usually pressure but can be twisting, bending, or vibrations.

The pressure sensor detects the pressure and can determine the amount of pressure by measuring the electric charge.

Pressure sensors are also installed next to filters in many industrial processes.

If the filter begins to clog, the flow will decrease. As the flow of the liquid decreases, pressure can increase or decrease depending on which side of the filter is monitored.

If you monitor the pressure, it will give you a simple indication that the filter is clogged and needs to be cleaned or replaced.

While there are many different types of applications for pressure sensors, there are many types of sensors available. 

Selecting a pressure sensor means choosing from a vast array of technologies, packages, performance levels and features in order to meet multiple demands for accurate pressure measurement.

Gauge Pressure

Gauge pressure is the pressure measured relative to the ambient atmospheric pressure. It can be positive for pressures higher than atmospheric, or negative for lower pressures. 

A gauge pressure sensor will have two ports, allowing the media at the reference pressure, and at the pressure. A typical application for a gauge pressure sensor is to measure liquid levels in a vented tank using the difference in hydrostatic pressure and ambient atmospheric pressure.

Absolute Pressure

Absolute pressure sensors will give the result relative to zero. Sensors will have one port for the media to enter and exert pressure on the sensing element, producing a positive change in output, of magnitude proportional to the pressure applied.

Absolute pressure sensors are also used in pressure measurement applications that will be used at different altitudes since atmospheric pressure varies with altitude, gauge pressure wouldn’t give an accurate reading.

Differential Pressure

Differential pressure sensors measure the difference in pressure between two points, similar to how a gauge sensor works. 

But in this case, the reference pressure is one of the points in the system, as determined by the system designer. The change in differential output is positive or negative, depending on which is greater. The magnitude of the change is proportional to the pressure difference between the two domains

Electronic pressure sensors measure a physical reaction to applied pressure by converting the resulting proportional change into an electronic signal. 

Commonly used phenomena include changes in capacitance, or changes in ohmic resistance of a strain gauge or piezoelectric element, which are proportional to the magnitude of the deflection when pressure is applied. 

The sensing principle used can influence accuracy, reliability, measurement range, and compatibility with the target environment.

The advent of smaller, lower-cost and lower-powered pressure sensors has increased efficiency and performance, and generated a new wave of innovation, in both the sensors themselves and their applications. 

As demand for these technologies is increasing, the worldwide pressure sensor market is estimated to grow to $11.4 billion by 2024. With a variety of different sensor technologies now available on the market, it can be difficult to know where to start.

This is why Mitsubishi, as one of the top-selling multinational automotive manufacturer, makes sure that they are creating, developing and studying the consistent production of sensors that are designed with the electronics protected from the media being monitored, and can be used on severe-duty applications without harm to the sensor.
