Przekładniki What Are? Technik Overview

A transducer is any device that transformats on e form of energy into anothr. In building automation, transducers typically convert non-electrical signals - such as temperatur, humidity, pressure, light intensity, or motion - intro analogg voltage or current signals, or into digital data packets. These signals are then interpreted by a building management system (BMS) or a programmable logic controller (PLC) to make control decions.
