Analog signals are the most basic process signals in automation process control systems, such as pressure, temperature, flow, etc. These signals are input forms that are transmitted through transmitters, converting the detected signals into standardized voltage and current signals, and sending these signals in real-time to the controller (PLC). PLCs convert these analog signals into … Read more
(In the control room of a food factory’s packaging line, Xiao A frowns at the ladder diagram on the PLC programming software, noticing that the counting function of the packaging machine is always inaccurate, with the number of cookie packages counted per hour being consistently less by more than 10 packages. Engineer Zhang approaches with … Read more
Ultrasonic sensors offer multiple advantages in industrial concentration measurement, making them an important analytical tool, especially in scenarios requiring non-invasive and real-time monitoring. These advantages are primarily reflected in measurement principles, applicability, and contributions to process control. 1 Non-Invasive Measurement Ultrasonic sensors measure by the propagation of sound waves without direct contact with the liquid … Read more
