As a vital part of the automation industry, PLC engineers face various challenges during commissioning and troubleshooting in the field. However, due to a lack of experience or simple oversight, engineers often make some reckless decisions that can significantly impact system performance or even cause safety hazards. These “fatal” mistakes can not only prevent smooth […]

15 Practical Rules Every Instrumentation Engineer Learns on Site In the field of industrial instrumentation, there is a saying many technicians know well: “Three parts theory, seven parts field experience.” You may memorize formulas and understand every detail of instrument principles, but once you arrive at the plant, the real challenge may come from something

In discussions about plant safety, you might hear terms like “alarms, interlocks, and safety valves.” However, true safety assessment goes beyond simply asking, “Do we have these systems?” It involves answering three crucial questions: What potential issues could occur? (Scenario Identification) Is the risk low enough? (Risk Assessment) If not, how reliable do the protection

Key Factors for Thermocouple Selection (Prioritized) Temperature Range (Primary Consideration) The temperature range determines the selection of the thermocouple type. The type should cover 1.2 times the maximum temperature (JB/T 5582-2015): Ultra-Low Temperature (-270 to -40°C): Type T (Copper-Copper Nickel), high precision for low temperatures. Low Temperature (-40 to 400°C): Type T (stable) and Type

An actuator’s dead zone refers to the range of input signals where the actuator does not respond. Only when the input signal reaches a certain threshold does the actuator begin to operate. When the dead zone becomes too significant, it may lead to oscillations in the control system, degrading the system’s performance. In industrial automation
