Pressure Transducers: Proper Grounding

Grounding error caused even 316L stainless steel to erodeThere are generally two approaches to grounding pressure sensors. Both work just fine, as long as they are used in isolation. However, when both are used together, problems can occur.

The first is to use a chassis, or case, ground. This means that the manufacturer has designed the transducer to make contact to earth ground through the case/housing of the sensor. This approach allows the transducer to be naturally grounded during the installation process.

The second approach is to use a...

Sensors and The Internet

Sensors now manufactured with the ability to connect to the InternetIn a report titled, “The Internet of Things”, McKinsey Quarterly outlines the benefits of technological advances allowing sensors to communicate over the Internet. The report discusses the trend that “objects are becoming embedded with sensors and gaining the ability to communicate. The resulting information networks promise to create new business models, improve business processes, and reduce costs and risks.”

The report points out two main processes that will see immediate gains from adding web-enabled sensors to objects. First, information and analysis is greatly aided since data that was previously unobtainable, can now be made available. Second, automation and control can be optimized due to the additional data.
