What is “Damping” in Industrial Equipment?

In the design and commissioning of industrial equipment, the following situations are often encountered: A buzzing sound when equipment is running Sudden, intense vibrations of cutting tools during machining Increasing loosening of motor bases over time Cracks appearing in pump machines after a few years of operation The root cause? Insufficient damping. Many people only

Protective Measures for Instrument Air Supply Lines in Acid and Alkali Corrosive Areas

In areas with acid and alkali corrosion, instrument air supply lines (compressed air pipelines) are prone to damage due to acid mist, splashes, or volatile gases, leading to gas leaks, contamination, and affecting the normal operation of instruments. Protective measures must be taken in terms of material selection, pipeline protection, installation layout, and maintenance. These

Flowmeter Selection Considerations

Choosing the right flowmeter is a critical decision that directly affects the accuracy, reliability, and efficiency of your flow measurement process. Here’s a comprehensive guide to help you select the appropriate flowmeter for your application. 1. Fluid and Operating Conditions (The Foundation of Selection) Accurate fluid characterization and working conditions are key to determining the

Troubleshooting Discrepancies Between Valve Position and DCS Display

When there is a significant deviation between the actual valve position and the DCS (Distributed Control System) display (i.e., the actual valve opening differs considerably from the DCS screen reading), process control can be affected. To resolve this, a systematic approach must be taken to investigate signal transmission, positioner calibration, actuator functionality, and DCS settings.

Why Zero Calibration Is Critical for Pressure Transmitters

In any industrial automation system, inaccurate pressure measurement can compromise safety, product quality, and process stability. A pressure transmitter is often referred to as the “nerve ending” of a control system. If its zero point drifts, every downstream control action — from PID regulation to safety interlocks — may operate on incorrect data. Zero calibration
