- AO910 Diffused silicon pressure transmitter
MeasuringprincipleThe product utilizes the piezoresistive effect of diftused silicon, a specific cystal orientation on monocrystallinesilicon wafers, to measure electrical bridges. By employing laser tuning and computer compensation algorithms, thetemperature characteristics have been significantly improved. The sensor has evolved from an early analog designto a digital one, enhancing the overall stability and reliability of the device.Mainfeatures
▶Thread straight installation, flange installation, quickconnection;▶Integrated and splitConventional industrial type (upper right figure), miniaturizedintelligent;Miniature outlet: Chersman, direct cable lead-out, aviationplugExplosion-proof: intrinsically safe (must be used in conjunctionwith the input type safety barrier), explosion-proof;Shell material: aluminum (conventional), stainlesssteel;Intelligent: support HART, menu setting;▶Non-intelligent: potentiometer adjustment;▶Display: LCD with backlight;▶Supports the Internet of Things, can be self-powered, 4G，NBlOT and other wireless output.applicationscenariosIt can be used in industrial sites for pressure, liquid level and other occasions, and can also be used in equipment pressure measurement supporting instruments.
