Instrumentation

Ensuring that instruments operate properly in high-temperature environments requires a comprehensive approach involving selection, installation, protection, and maintenance. Different types of instruments, such as sensors, transmitters, and displays, require tailored solutions. The following strategies outline how to address these needs: 1. Selection: Choose High-Temperature Models 1.1. Core Component Temperature Compatibility Sensors: Choose sensors made from […]

In modern industrial automation, level detection is a critical aspect to ensure continuous production and safety. Whether it’s chemical storage tanks, powder silos, or ash systems in power plants, accurately monitoring the material’s position is essential for stable operations. Among various measurement technologies, radio frequency capacitance (RFC) level switches are gradually becoming a mainstream solution

In the era of industrial automation, efficient communication between devices is crucial. Modbus, as a widely used communication standard, allows different devices to exchange data. However, with the advancement of internet technologies, converting Modbus data into HTTP protocol provides an easier way to achieve remote control and monitoring. This article discusses why it’s essential to

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

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
