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).

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 Are The Different Types of Pressure Tests for Engine Test Stands?

Did you know that companies spend hundreds of millions of dollars on research and development for off-highway vehicle engines? A portion of the R&D goes into developing specialized engine test stands to ensure that the engines are functioning properly.

Engine test stands are complex, engineered systems designed to measure, control and record parameters during the different engine manufacturing stages.

What is a Hydrogen Fuel Cell and How Does it Work?

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.

What is Capacitance?

Capacitance is the ability of an object to hold an electrical charge. Capacitors are components in an electrical circuit that can store a charge and are considered one of the three fundamental electronic components along with inductors and resistors.
