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
Have you ever noticed the numbers on the top of a bolt—like 8.8, 10.9, or 12.9? These are not just random figures; they represent the strength grade of the bolt, and they hold the key to ensuring safety and reliability in various structures, from bridges to wind towers to industrial buildings, and even in your

In modern industries such as chemicals, oil, pharmaceuticals, food, and environmental protection, level measurement plays a critical role in process control. For special media environments that are corrosive, prone to crystallization, high-viscosity, or prone to solidification, traditional differential pressure transmitters with capillary tubes often experience blockages, corrosion, or signal drift. In these cases, dual-flange level

During a recent device debugging session, I encountered an unstable RS485 communication issue. It reminded me of a fundamental yet crucial point: why must the voltage of an RS485 signal be confined within the -7V to +7V range? Many people may know this as a requirement but may not fully understand the reasoning behind it.

Calibration ensures that instruments and equipment provide accurate and consistent measurements. While professional calibration typically requires specialized tools and expertise, non-professionals can perform basic calibration tasks for routine checks or when high precision is not mandatory. Below is a detailed guide to help non-professionals calibrate instruments and equipment effectively. 1. Understand the Calibration Needs Before

Overloading phenomenon is a common issue in the batch material dispensing control process. Specifically, when the total dispensing amount reaches the preset value, the controller immediately sends a signal to close the valve. However, due to system lag and inertia, some fluid continues to flow towards the receiving end, causing the final dispensing amount to
