WebSep 13, 2024 · A differential pressure sensor is a device responsible for measuring the difference between two pressures. These two pressures are connected to each side of the differential pressure sensor. They also measure pressure drops across oil or air filters. They can measure fluid levels as well by measuring the pressure between the above and below … WebFeb 14, 2024 · How Does an H2S Detector Work? Hydrogen sulfide gas detectors primarily use electrochemical sensors to detect and measure parts-per-billion (‘ppb’) and parts-per-million (“ppm”) levels of H2S gas. These sensors depend on a highly reliable electrochemical reaction that occurs when H2S gas combines with specific materials used in the sensor.
