Understanding Active/Passive Transmitters and DCS I/O Module Powering Modes via Jumper Settings

PLC /

For automation engineers, terms like active, passive, powered, and non-powered are commonly encountered. However, many still struggle to clearly differentiate and relate these concepts. This article explains the relationship between transmitter types (active/passive) and DCS I/O card power configurations (powered/non-powered), using a real-world example of the XP351 8-channel AI module. 1. Core Concepts Active vs […]

Is Cable Shield Grounding Still Necessary Between Cabinets When Using Intrinsically Safe Barriers?

Instrumentation /

✅ Executive Summary The presence of intrinsic safety barriers (IS barriers) in a system does not eliminate the need for proper cable shield grounding between control cabinets. Shield grounding and IS barrier functions serve different engineering purposes and must both be correctly implemented to ensure signal integrity and system safety. ⚙️ 1. Misconception: “Shield Grounding

What Is Level Transmitter Range Migration?

Level meter /

1. Understanding Level Transmitter Migration Range migration refers to the adjustment of a level transmitter’s measurement range so that it accurately reflects the actual liquid level. In certain installations—such as when the transmitter is not mounted at the zero-level reference, or when special process media or sealing fluids are involved—the raw pressure readings may deviate

Should Instrument Conduit Drain Holes Be Sealed or Open?

Instrumentation /

The Recurring Problem That Keeps Getting “Corrected” Year After Year “Seal the drain holes!”“No, open them!”For many industrial plants, this back-and-forth has become a frustrating ritual during every inspection. Despite repeated rectifications and compliance efforts, this “small issue” surrounding instrumentation conduit drainage continues to resurface. Why is this happening? Do the standards really say nothing

Is the Absence of a Red Mark on a Pressure Gauge a Safety Hazard?

Pressure Transmitter /

In industrial operations, it’s common for engineers and inspectors to ask:“Must every pressure gauge have a red line indicating the maximum working pressure?”And if a gauge lacks this red mark, does it represent a safety hazard? Let’s explore this question from three critical perspectives: the purpose of the red mark, relevant regulatory requirements, and practical
