Comparing the Model 209 and Model AXD

Advancements in technology have created a need for enhanced pressure sensing technology, the next generation of pressure transducers. To meet this new demand, we designed the Model AXD, the updated and improved version of the Model 209. The Model AXD is built leveraging the strength of the 209's variable capacitance sensor paired with a new electronics platform. With enhanced performance through digital signal conditioning and a rugged, laser-welded construction, the Model AXD has the reliability and accuracy necessary for industrial and OEM applications.

How to protect transducers from electromagnetic and radio-frequency interference

Design engineers have a lot to consider when selecting components for use in end-user products and equipment. Original Equipment Manufacturers (OEMs) that follow a strict Design for Manufacturing and Assembly (DFMA) methodology will have few, if any, problems with pressure transducers. However, OEMs that do not adhere to DFMA practices in their factory increase the likelihood of reoccurring issues, including transducer failure.

3 Overlooked Design Considerations When Choosing a Pressure Transducer

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.

What does shock and vibration do to a pressure transducer?

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.

What is Hysteresis?

Hysteresis Defined

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.

What is the difference between strain gauge and capacitive transducers?

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).
