Intrinsically Safe
Magnetostrictive Level Sensors
Series: MPI
®

US
The MPI Series Intrinsically Safe Magnetostrictive Level sensor provides highly accurate and repeatable level readings in a wide
variety of liquid level measurement applications. The MPI-R’s large, buoyant, and robust oat allows for use in harsh applications
where fouling or buildup might otherwise be of concern. The MPI-E’s lighter weight design allows it to be used in applications
where space is limited. The MPI-E Chemical has a chemical resistant coating, allowing for use in corrosive, acidic, or marine envi-
ronments. The MPI-F’s exible stainless steel stem allows for installation in tall tanks without needing a crane, and the MPI-T’s 1”
titanium stem provides compatibility in a wider range of corrosive media--including H2S--in larger tanks.
Features
• Class I, Division 1, and Class I, Zone 0 Hazardous Location
Rating (cCSAus, ATEX, IECEx)
• Highly accurate and repeatable readings
• RS-485 (Modbus RTU) output
• Rugged and reliable, lengths up to 25 feet (7.62 m)
