How to Troubleshoot a Pressure Transducer

Pressure transducers today are more rugged and reliable than ever. Made of stainless steel construction, they provide abundant overpressure protection, improved total error band, and offer negligible orientation and vibration effects. They are ideal for long-term use even in harsh environments of extreme temperature, humidity, and vibration.

What is Total Error Band & How do You Calculate It?

Total Error Band (TEB) is a measurement of worst case error; it is the most comprehensive and concise measurement of a sensors true accuracy over a compensated temperature range.  TEB is extremely important to know when trying to determine how well a sensor will work within a particular design system. By calculating TEB you'll be able to understand the different possibilities for error. Formulating TEB can be tricky if you don't have the right inputs readily available.

Make Halloween Spookier with Pressure Transducers

Happy Halloween From Setra

Have you ever wanted to build your own Haunted House or Spooky Trail?

I'm sure we've all thought about it one time or another. You know what I'm talking about. Places like amusement parks, fairs, or even a homemade one that your “Halloween Crazed” neighbors down the street built themselves. But how do they work?

6 Things OEM Design Engineers Need to Know

Any design engineer must seriously consider the manufacturing environment when looking to select a pressure transducer for inclusion within a refrigeration chiller, pump, engine test equipment, or other machinery. The life of a pressure transducer is proportional to the system design and assembly process.

Accuracy: End Point Method vs. Best Fit Straight Line Method

Which method provides better accuracy?  Non-linearity as the End Point Method is the relationship of the calibration curve to a specified straight line through its endpoints (i.e. Zero and Full Scale). Best Fit Straight Line (BFSL) method is the relationship of the calibration curve to a calculated straight line that minimizes the error but does not pass through the end points. BFSL method effectively cuts the end point value in half.
