In the field of instrumentation and process control, theory is like a wrench—it may seem insignificant, but when it matters, it’s essential. Whether for obtaining basic certification or for daily tasks, concepts such as circuit diagrams, sensor principles, and troubleshooting are crucial. This series will continue to update, helping you master theoretical knowledge while providing
In industrial maintenance, instrument technicians often face the dilemma of using a high-precision multimeter but struggling to accurately determine the temperature or check the health of resistance thermometers (RTDs) and thermocouples. Why can’t we get the correct temperature even after measuring the resistance? Why does the millivolt reading from the thermocouple never match the actual

1. Don’t Be Fooled by “Surface Calmness” One of the biggest misconceptions in workshop safety is the familiar saying, “If no hazards are found, then everything is safe.” Just because the equipment is running smoothly and the floor looks clean doesn’t mean everything is in order. Many accidents occur in environments that initially appear to
Not Finding Hazards Does Not Equal Safety Read More »
In industries like chemicals, petrochemicals, and storage, ensuring the safety of storage tanks is a critical and complex task. Among various safety measures, pressure alarm systems play a foundational and essential role. Like a “warning system” for the tank, these alarms trigger immediate alerts when internal pressure rises abnormally, allowing operators to take action and

In an industrial setting, a common issue arises when a process tank is equipped only with a magnetic float level switch (magnetic float type) without a remote transmission feature, making it impossible for the central control system to monitor the level. In such cases, instrumentation solutions must be explored to provide remote level transmission. This
