Solid State Digital Liquid LevelTechnical Specifications Solid State Digital Liquid Levels (DL) are built to flawlessly operate in difficult environments, consistently providing highly reliable liquid level information. The durable design will withstand most chemical exposure with a life expectancy over 10 years. • Measures water level, gray water and other conductive liquids; • Solid-state technology with no moving parts or open ports; • Natural immunity to shock and vibration; • Durable nylon casing potted with chemically inert epoxy; • Tefzel (M22759/16 spec) double shielded chemically inert connection wire. • i2C digital Interface with +5V power ; • Correction and calibration parameters stored in internal NVRAM; • Integrated upper and lower temperature sensors. • Seamless integration using the provided sample “C” code and libraries Page 1 | Solid State Digital Liquid Level Technical Specifications : May, 2018 - Rev. 01C | samcontrollers.com Copyright © 2018 SAM Controllers / UTI - All Right Reserved Manufactured and Engineered in Pit
