A combustible gas detector that reads 20% LEL in a clean area, or reads zero during a real leak, is a safety problem and an operational one. False alarms erode trust, and false lows can …
A flame detector that keeps dropping into fault is more than a nuisance. Every fault means that zone is partly or fully blind to a hydrocarbon fire, and every repeated fault teaches operators to ignore …
A gas detector doesn’t measure gas in a vacuum. It measures gas in a real plant, refinery, rooftop, or confined space, where the air is hot, cold, damp, dusty, or at a different altitude than …
A gas detector that cries wolf is a safety risk. When operators see alarms that never turn out to be real, they start to ignore them, silence them, or push the alarm setpoints higher. Eventually a …
Sensor drift is the gradual change in a sensor’s output over time when the gas concentration, or the measured condition, has not changed. In gas detection, it is one of the most common reasons an …
Troubleshooting gas detectors comes down to one question: is the instrument telling the truth? Most problems fall into a handful of categories: power, sensor health, calibration, sampling path, environment, and (for fixed systems) wiring. Work …
A gas detector that won’t zero, or fails span during calibration, is one of the most common problems in the field. It is also one of the most misdiagnosed. Technicians replace perfectly good sensors, and …
I work in gas detection, and one of the common quuestion I get is do I need a fleet management software? when I should get it and when it is not worth it, here is …
I have been working in the gas detection industry for the last 8 years and one of the most frequently question i get is how to select the right fixed gas detector. How to Select …
If you work anywhere near radioactive sources, radiography operations, nuclear facilities, or even certain oilfield logging tools, a gamma radiation detector isn’t optional equipment. It’s the instrument standing between a normal shift and an unrecognized …
