The Many Pressure Sensor Uses

Posted on April 20, 2020
Pressure sensors

Pressure sensors are some of the handiest tools you’ll find when you browse our product range. Furthermore, there are many pressure sensor uses.

What makes them handy? You ask.

The answer is simple; we can use these sensors for a wide variety of control and monitoring purposes. Thanks to pressure sensors, we can accurately and conveniently measure variables such as fluid flow; water level, speed and altitude, for example.

Pressure sensing is required in many different places. You’ll find its use in weather instrumentations; in automobiles, in aircraft and frankly, and any other machinery you can think of that has pressure functionality.  

In this article, we will be breaking down the uses of pressure sensing, and we will be showing you how it can help you to better clamp down on your control and monitoring.

Pressure Sensor Uses

How do pressure sensors work?

Before we dive into their uses, we need first to understand how they work.

The way a pressure sensor works is it creates an electrical signal when you force pressure upon it. You’ll find that the generated signals tend to be digital or analogue; although, visual, optical and auditory signals are also widely in use.

You still with us? Great. Now, why don’t we take a look at their uses?

Types of pressure sensors

With a wide variety of pressure sensors available, it can be tough to choose the one that is best suited for you and your tasks.

When it comes to sensors, there is not a one-size-fits-all; different pressure sensors will serve different purposes.

Below, we’ve broken down some of the sensors we offer here at OMNI.

Absolute pressure sensors

Firstly, think of ‘absolute pressure’ as pressure that is measured relative to the zero pressure you’d find in the empty, air-free space of the Universe.                                                                                    

Do you know what that means? It means that unlike other sensors, absolute sensors can create readings that are not swayed by the shifts and changes of the atmospheric pressure down here, on our earth.

Gauge pressure sensor

Gauge pressure is measured relative to the atmospheric pressure you’ll find in the air around you. What this means is that changes in the atmospheric pressure can alter the output of a gauge sensor. 

Differential pressure sensor

You can use these sensors to measure the difference between any two pressures.

The uses of pressure sensors:

You can use pressure sensors to improve the quality of your indoor air:

Here’s how it works:

Every building requires a different amount of airflow, depending on the number of people inside it.

Think about your work environment, for example – how many people work there? Are all the employees clustered together in one tight space?

You must remember that the bigger the crowd of people in a tight space, the higher the level of CO2 emitted. Where’s the issue? Well, the issue is that high levels of CO2 can lead to a host of health effects.  

Luckily, there is a solution.

Thanks to the help of pressure sensors, there are ways for you to monitor the CO2 in your work environment closely.

When you can measure the airflow and pressure in your environment, you can optimise your use of heating, cooling and ventilation. Pressure sensors are an excellent way for you to increase the efficiency of your HVAC system by helping you to reduce energy use and costs.

You’ll also find pressure sensors in cleanroom applications. In cleanrooms, they monitor and assess air pressure, air quality and ventilation, which are all important factors in a cleanroom.

The pressure sensor uses don’t stop there – you’ll find these sensors nearly everywhere you turn:

Here at Omni, we offer a wide variety of highly-accurate sensors that can help you to tackle measurement challenges.
