Sensitivity in Instrumentation Sensitivity of an instrument is defined as its ability to detect small changes in the input quantity, i.e., how responsive an instrument is to changes in the input. Mathematically, it is represented as the ratio of the change in output to the corresponding change in input. High sensitivity means that even small

Introduction In industrial processes, instrumentation failures can lead to production interruptions, false alarms, or even safety hazards. However, many failures are misdiagnosed due to neglecting critical contextual factors such as process conditions or environmental influences. This article presents a three-step diagnostic method that combines process analysis with instrument characteristics and field conditions to help engineers

Introduction Hydrogen leak detectors are a critical part of any hydrogen safety system. However, the market is saturated with flashy claims such as “ultra-sensitive,” “high-precision,” and “lightning-fast.” These often mislead users during selection. Poor choices can result in frequent false alarms, higher maintenance costs, or even failure to alert during a real leak—compromising plant safety.

Introduction In industrial automation, the choice of signal transmission is critical to the reliability and stability of the control system. Among the various methods available, the 4-20mA current signal has become the de facto standard. But why is 4-20mA preferred over alternatives like 0-20mA or 0-10V? This article explores the technical, practical, and safety reasons
