If you require a pressure measurement instrument, you might notice that there are quite a few types on the market that do that job for you. For instance, the most commonly used pressure measurement instruments generally fall into one of these three types: pressure controllers, indicators, and transducers. But how do they differ? And which of the three is best suited for your needs?
In this post, we’ll offer a brief overview of each of these pressure-measuring instruments and describe how they perform different functions. If you have questions about which instrument will fit your requirements or need help calibrating yours, you can contact our team at National Weighing & Instruments.
Also known as pressure calibrators, these instruments are excellent for measuring and regulating pressure in an automated manner. Pressure controllers use a supply pressure to regulate the pressure quickly and automatically within your test instrument or device, before displaying it on a digital screen. They provide many control functions and output control signals.
These easy-to-use instruments simplify pressure calibration, making them a popular choice with manufacturers or laboratories of all sizes looking to streamline their operations. Of the three instruments on this list, pressure controllers are the most all-in-one solution since they have an easy-to-read display and generally do not need to be integrated with other devices.
To understand what pressure indicators, do, all you have to do is look at the name. Pressure indicators (also called pressure gauges) are designed to read and display the pressure of an instrument. You could think about them as a more stripped-down version of a pressure controller.
While pressure indicators have a bit less functionality than pressure controllers, they are still effective instruments for calculating pressure. They’re suitable for manufacturers who need to quickly understand the pressure of their instruments but don’t need the comprehensive capability of a pressure controller.
Finally, pressure transducers (also called pressure transmitters) are the simplest of these three instruments. Rather than presenting the pressure on a display, transducers identify the device’s pressure and convert it into an electrical signal. When you connect an external device to the pressure transducer, you can read the signal and determine the pressure.
Now that you understand the key similarities and differences between these three types of instruments, you might be thinking: which one is right for me? The truth is that it depends on several factors, including your budget and how you intend on using the instrument.
However, whichever pressure measurement instrument you decide to use, National Weighing & Instruments can help ensure that it is properly calibrated to provide you with the accurate measurements that your business or laboratory requires.
