![]() Using these reversed signals, they give a positive reading when the pressure measured falls below atmospheric pressure. Vacuum pressure transducers measure pressure in the opposite direction. Differential pressure can therefore be measured using the degree by which the diaphragm deforms.ĭifferential pressure sensors are most often needed for applications within remote water-based heating systems, offshore gas and oil processing, and in waste treatment plants. If the pressure changes or differs between the two chambers, the diaphragm deforms in the direction of the chamber with negative (lower) pressure. These are separated by a diaphragm, which sits in the middle of the two chambers when they're both equal in pressure. Each sensor consists of two chambers within a cylinder – one for positive pressure and one for negative pressure. Differential pressure sensorsĪ differential pressure transducer functions in relation to the static differential measurement principle. In an absolute pressure sensor, the measurement is made possible by comparing a target pressure with the known pressure of a vacuum. Absolute pressure sensors are required in navigation systems, engine manifolds in gasoline and diesel vehicles, and industrial packaging. These sensors are not limited just to measuring the pressure of air or gas, and they work slightly differently to transducers. Pressure transmitters require a power supply, which might not suit applications that demand long-term use. Many pressure transmitters are manufactured with customizable settings, including zero/span adjustment and turndown. They benefit from extra circuitry and can linearize, amplify, and compensate the output received from a transducer. Pressure transmitters build on the capabilities of transducers, making them a superior option for those seeking more data to interpret and analyze. Pressure differential transmitters vary from transducers, though the terms are often confused or used interchangeably in industrial contexts. Pressure management enables workers and researchers to access important data to refine and improve the quality, safety, and efficiency of modern systems. However, the need for accurate and reliable pressure transducers throughout industrial settings is higher than ever. Many pressure sensors are transducers, but it's important to bear in mind that the signal converted by transducers is always analog electrical output – typically as millivolt per volt. Pressure transducers are sensors that convert readings into electrical signals. ![]() We stock a vast selection of gauge pressure sensors, so please don't hesitate to get in touch if you'd like some help finding the right model. Sealed gauge sensors are fixed to a pressure reference point, usually of one bar, while vented gauge models operate at atmospheric pressure levels and constantly fluctuate. Gauge pressure sensors measure pressure relative to atmospheric pressure. It's the most common pressure measurement, so you'll find a wide variety of sealed gauge and vented gauge pressure sensors in our online range. Gauge pressure is that which is measured above atmospheric pressure. A few of the most integral types of pressure sensor include: Gauge pressure sensors However, it's also essential to make sure you obtain the correct sensor type for your desired application. Browse the collection now to discover models from leading brands such as: You can use our handy filters to narrow your search by manufacturer, output, measurement units and range, supply voltage, and more detailed criteria too. In turn, both analog pressure sensors and digital pressure switches help to increase process efficiencies and lower operational costs. Output signals from pressure sensors provide engineers with the ability to adapt systems according to specific requirements. These make up most industrial pressure sensors. A device that can detect atmospheric pressure is known as a barometric pressure sensor. Pressure sensors are devices that detect pressure and convert it into an electric output signal. What are pressure sensors and why are they needed? No matter your industry, we're sure that you'll be able to find the right pressure sensor here. Above all, pressure monitoring is crucial for efficiency and profitability.Īt RS, we're one of North America's leading suppliers of electrical components and supplies for commercial applications. Likewise, a low-pressure sensor could help prevent machine breakdowns and leaks in heating systems. If machines and their internal components reach higher pressures than those with which they're designed to cope, the risk of serious damage or even explosion increases. Not only does monitoring pressure accurately enable efficient processes in a manufacturing environment, but pressure sensors also play an integral role in workplace safety. In any industry, access to fast, reliable, and durable pressure-measuring devices is essential.
