Technicians at the Kennedy Space Center often work in cleanrooms, laboratories with high degrees of cleanliness provided by strict control of particles such as dust, lint, or human skin. These facilities must be contaminant-free environments where the air is repeatedly filtered and surfaces are smooth to prevent particles from getting lodged.

There are many applications for differential pressure transducers, but none are more critical than those measuring the pressure parameters in a cleanroom. A cleanroom is a critical area used to manufacture medications, containers, enclosures, and other medical devices that require the products to remain sterile from manufacturing through delivery to the customer. The products manufactured in these environments are used to treat and care for the general population and are handled differently than other products.
From August 14th through the 17th, Setra Systems will be exhibiting at the NCSL International Workshop & Symposium taking place at the Gaylord National Convention Center in National Harbor, MD.
The theme of this year’s symposium is “Precision & Performance with Measurement Science”:
There are numerous environmental factors that can interfere with the performance of a pressure transducer. Two commonly overlooked factors are shock and vibration. Knowing the system where the pressure transducer is installed can help avoid high shock and vibration conditions, minimizing premature failure of your instrumentation.

According to Merriam-Webster, hysteresis is the “lagging of a physical effect on a body behind its cause (as behind changed forces and conditions)”. When outside forces act on an object, that object will either immediately spring back to its original state, or more likely, it will somehow change or exhibit properties from previous deformations.
Setra is best known for pioneering the variable capacitance principle, the technological innovation behind capacitance-based pressure transducers. Variable capacitance transducers demonstrate industry-leading accuracy especially in low pressure HVAC and critical care applications with accuracies as high as ±0.25” water column (±0.009 PSI).
In many pressure sensing applications, high accuracy is a must-have. Whether you’re working with thousands of PSI or only a quarter inch of water column, the most demanding jobs require the best tools available. While there are many types of pressure sensing devices on the market, none quite match variable capacitance transducers in terms of accuracy and quality.

As of July 22, the RoHS exemption for industrial monitoring and control instruments will end. Non- compliant product cannot be CE marked and sold in the European Union or to customers who otherwise require the CE mark.
When first selecting a pressure transducer for a new project or piece of equipment, designers typically focus on key design parameters such as pressure range, electrical output, media compatibility and environmental conditions. However, those parameters are not the only ones to consider when making a smart choice for an application. There are three design considerations that are often overlooked when selecting a pressure transducer: transfer medium (oil filled vs. non-oil filled), construction, and type of sensing technology.

Although hydrogen is in its infancy as a fuel source, its future is incredibly bright. The technology behind hydrogen fuel cells is improving by the day and its viability as a replacement to the internal combustion engine seems likely. Hydrogen is already being used in specialty vehicles such as forklifts and buses, and it’s only a matter of time before infrastructure is in place to serve the consumer automotive market. Why do hydrogen fuel cells have such great appeal? Because their only byproducts are heat and water vapor, making hydrogen fuel cells a truly zero-emission locomotive technology.
