Pressure sensors are used across a variety of industries to provide accurate, real-time data of how a process or system is operating in a given application. But how can you tell if your data is accurate? The most common method to ensure the accuracy of sensor output is to calibrate your sensor against a higher accuracy pressure sensor (calibration standard). Now, how can you tell if your calibration standard is accurate?  This is where measurement traceability plays into the calibration process.

Whether it is a commercial, retail or industrial building, pressure sensors play a significant role in monitoring the building for occupants’ safety and comfort. When integrated with pressure technology, HVAC systems can operate at optimum levels as well as improve building maintenance. Three ways this can be done are:

After selecting your pressure transducer, it is now time to select a power supply. It is important to select the proper power supply to ensure all components are functioning properly and recording accurate data. 

Although there are a variety of methods for leak detection, the most common is pressure decay. Other methods can be time consuming and costly, whereas pressure decay leak detection is a simple test that's sensitive to very small leaks. This method is ideal for high-volume industries that require quick accurate tests within their facility. By pressurizing the unit under test (UUT) and then removing it from the pressure source, any detection of pressure loss is a result of a leak within the UUT. Before performing a pressure decay leak detection test, make sure your system is properly setup.  After the system is setup, follow the below steps to test the UUT with a differential pressure transducer.

In the test and measurement industry, manufacturers need to test the products they build. Pressure sensors are needed in test stands to measure pressure across various mediums, including air, fuel, coolant, gas. Testing can be expensive and having a reliable sensor eliminates costly downtime.

Material Compatibility refers to a material's resistance to corrosion, rust or stains when it comes in contact with a chemical.

Hydrogen is used as a process media across many different industries and applications. Used in OEM equipment, pressure sensors play an important role in the safe, efficient, and reliable operation in material handling equipment, power generation, hydrogen production/distribution and many other applications.

After understanding the difference between wet-to-wet, wet-to-dry and dry-to-dry differential pressure transducers, it is time to learn about the different types of sensors designed to measure wet-to-wet differential pressure. Wet-to-wet differential pressure sensors are broken into two main categories, true wet-to-wet differential pressure and calculated wet-to-wet differential pressure.

Differential pressure is the difference in pressure between two points of measurement. This is commonly measured in units of pounds per square inch differential (PSID) or in inches of water column (“WC). Devices for differential pressures usually fall into one of these three categories:

When selecting an industrial pressure transducer for monitoring high temperature liquids or gases be sure to check the operating temperature range of the transducer, in order to select the correct pressure transducer for these applications.
