The first and most important consideration is pressure. A number of questions must be answered to ensure the correct transducer is selected. What is the pressure range that the transducer will measure? What is the maximum pressure the transducer will encounter? What is the potential for over pressure in the system?

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.

Newly Added Restricted Products Under RoHS2 Affects Manufacturing
In 2013, RoHS2 was created by the European Union legislation, nearly a decade after the original RoHS (Restriction of Hazardous Substances Directive) was implemented. RoHS2 is merely an evolution of RoHS1 that provides greater clarity on the legal scope of products that should adhere to the hazardous material guidelines. The combination of

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

Although there are a variety of methods for leak detection, the most common is pressure decay. Other methods can be time consuming and costly, whereas pressure decay leak detection is a simple test that's sensitive to very small leaks. This method is ideal for high-volume industries that require quick accurate tests within their facility. By pressurizing the unit under test (UUT) and then removing it from the pressure source, any detection of pressure loss is a result of a leak within the UUT. Before performing a pressure decay leak detection test, make sure your system is properly setup. After the system is setup, follow the below steps to test the UUT with a differential pressure transducer.

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.
