Instrumentation

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

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

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

Industrial Control Systems (ICS) are the “nervous system” of key sectors such as manufacturing and energy supply, and their network security directly determines the stability of production and even the safety of physical environments. However, many technicians encounter confusion when dealing with ICS security. Today, we will clear up some common but often overlooked points.

The UQK-6100 series float level switch operates by utilizing the buoyancy principle of Archimedes. As the float moves with the liquid level, the primary magnet inside the pressure tube moves vertically. The mechanical switch, which is adjustable, is located outside the pressure tube in the housing. The movement of the primary magnet triggers a secondary

1. Why is Air Tightness Important? Whether it’s a new energy vehicle battery pack, a high-pressure gas pipeline, or a semiconductor vacuum etching machine, their operational stability hinges on an invisible parameter—air tightness. Air tightness testing is not simply about detecting air leaks; it’s a systematic safety validation and process control method. It determines whether:

Behind the complex codes and systems, lies the key to a company’s future success or failure. “Transform or die, stagnate and perish.” This has become the harsh reality for 70% of companies today. In this silent war, a new department—the Digital Transformation Department—is quickly rising in many organizations. From traditional manufacturing to internet giants, from

I. Daily Inspection Guidelines Inspections should combine visual, auditory, tactile, and measurement methods to ensure the system is functioning optimally. 1. Visual Inspection Steam Supply and Condensate Drainage: Check if the pressure in the main steam line and steam headers falls within the normal range (typically 0.3~0.8MPa). Observe the condensate drain for proper discharge of

In the field of chemical manufacturing, safety is not only a moral responsibility but also a core element of sustainable operation. In China’s chemical safety management framework, the term “Two Key Points and One Major” forms the foundation of process safety control. However, many companies know the concept but struggle with implementation. This article explains what
