When you have a question about process automation that needs a short answer, such as this one about what a pressure transducer is, let us know with #WishIknew and #Visaya! We’ll reply with a #WishIknew post. It’ll give a quick explanation, then some related articles, videos, or reviews if you want to know more.
Some people think that “pressure transducer ” and “pressure transmitter” mean the same thing, but they don’t. All pressure transmitters have pressure transducers and some even have more than one. Actually, some have more than one. But this doesn’t answer your question.
What is a pressure transducer?
A pressure transducer converts the pressure on your sensor into an analog signal. Sometimes it does that from inside a transmitter. And that’s how it gets confusing.
Transducers work great for small spaces, and the output usually ranges between 0 and 100 millivolts. More often than not you use them with amplifiers. Pressure transducer sold without amplifiers are often called “bare” transducers.
