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.

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?

Absolute pressure is measured relative to a full vacuum (0 PSIA = 14.7 PSIV). The electrical output of an absolute pressure transducer is 0 VDC at 0 PSIA and full scale output (typically 5 VDC) at full scale pressure (in PSIA). PSIA (pounds per square inch absolute) is a unit of pressure measured relative to a full vacuum. A vacuum can refer to any pressure between 0 PSIA and 14.7 PSIA.

Low pressure measurements are required in various applications such as air flow, static duct and cleanroom pressures in HVAC and energy management systems (EMS). Other applications include use in medical instrumentation, environmental pollution control, boil combustion efficiency and a wide variety of research and development requirements. Although the focus will center mainly on air flow and pressure, the same principles

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.

One factor that should be considered when selecting an industrial pressure transducer for monitoring high temperature liquids or gases is the operating temperature range of the transducer. This specification is included under environmental data on most manufacturers' data sheets.

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.

The following steps clearly indicate the exact sequence to properly troubleshoot a Setra 2 wire, mil-amp circuit. You must work with the assumption that either the Setra product or the system & circuitry is bad.

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.
