Training Posts 🔍 Confused about the terms transducer and transmitter? You're not alone! 🤔 Let's clear things up and understand the differences between the two. A transducer converts energy into an electrical or electronic signal, while a #transmitter not only senses the physical variable but also transmits a standardized electrical signal representing it. For instance, a pressure switch is a digital device with two conditions - open or closed, making it perfect for connecting to a PLC digital input module. On the other hand, a pressure transmitter combines a sensing transducer with a circuit that transmits a 4 to 20 mA electrical signal, providing precise #measurement of the physical variable. Understanding these distinctions is crucial for accurate and reliable data acquisition. Don't let the terminology mix-up hold you back! Click here for more Training Posts
