Bluefin Sensor Technologies has been focusing on the R&D and production of level sensors since early 2016. Our key staffs have more than 10 years' hands-on experiences in industry. Our traditional main customer base is in the field of diesel-powered vehicles including trucks, buses, power-generators, marines, construction machineries, agricultural machineries and gardening machineries, who have been using legacy products for decades. In parallel, we succeeded in creating more new higher-end product families by using state-of-the-art electronic technologies and stepped into new fields of application including fleet-management, water filtration & treatment, new-energy power equipment and many more others. Bluefin has leading-edge design and manufacturing capability in build up sensors with fine-resolution, minimized upper dead zone and lower dead zone for high-demanding applications " What could Bluefin do for users: 1. Sensors with special geometry 2. Sensors with integrated and separate harness 3. Sensors with miniaturized and light-weighted designs 4. Integrated and tested level-gauge, level/pump controller and alarms together with level sensor" 5. Sensing resolution of 35mm, 21mm, 10mm, 7mm, 5mm and 4mm 6. Sensor and switches compliant to drinking-water safety 7. Top-mounting, side-mounting, bottom-upward mounting and lock-nut mounting design level sensor or switches Bluefin is 100% fully open to requests of customized design. "Not only do we supply the level-sensor as the stand-alone unit, but we could also put together level-gauge, controller, harness, mounting accessories and others, and ship all units as tested & validated turnkey solutions" "level-sensor could output the level signal in the form of resistive, voltage or current for different field applications of the users. " "Besides most-common top-mounting design, we have special product variants with design of side-mounting, bottom-upward mounting and Lock-nut mounting to work with different tank's design and limitation of mounting space " Bluefin's mechanical level gauge works nicely to wide-range of tank's height ---from 120mm through 1600mm in height. " "The gauge senses level variation without electrical power. It is easy-to-use, economical and reliable, and has nice performance both in mobile and stationary applications. " "We supply options of mounting accessories--- no matter the tank's mounting port design is thread-in, 6-hole bolt flange or bayonet twist-and-lock" Bluefin's gauge has a fully isolated dial, we guarantee no liquid penetration to dial. Options of O-ring sealing or epoxy-sealing give water-proof against the ambient with IP64-grade or IP67-grade.
