Hydrogen Energy Pressure sensors sold at low prices

Product description

At present, the most common hydrogen pressure transmitters are catalytic type, electrochemical type, electrical type (metal oxide semiconductor, Schottky diode, etc.) and thermal pressure sensors. In addition, optical sensors are becoming more and more popular because of their advantages such as no spark and strong anti-electromagnetic interference ability. Catalytic hydrogen pressure sensor detects combustible gas by electric heating of gas oxidation on the surface of catalytic element. This oxidation requires harnessing the oxygen in the air and releasing heat, raising the temperature of the sensing element depending on the concentration of the gas. The most common type of catalytic sensor is the "flow type," which consists of two ceramic beads embedded with platinum wires. One of the ceramic beads is covered with a catalytic material that oxidizes when it encounters hydrogen, causing the temperature on the bead to rise, which changes the resistance of the platinum wire. At the same time, the platinum wire also acts as a heater, requiring the ceramic beads to be heated to the specified temperature in advance. Wheatstone Bridges require accurate measurement of resistance changes caused by temperature changes.
