4 Critical Tips For Eliminating Electrical Noise

Stop electromagnetic interference!Electrical noise, also known as electromagnetic interference, can destroy a clean signal from your measurement instrumentation (such as level sensors and pressure transducers). Protecting your sensors from electrical noise is a top priority. Luckily, this is a fairly simple task in most cases.

There are a couple of ways to keep electromagnetic interference (EMI) at bay. You need to use properly shielded cable, you must be careful when routing your cables, and your sensors need to be grounded properly. Finally, it’s important that the signal output is appropriate for the electrical environment.

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...
