Intrinsically Safe, Chemically Resistant Magnetostrictive Float Level Transmitter

MPI-E Chemical

Anti-Corrosion Coating and Class I, Div 1 Ratings

The MPI-E Chemical is an Intrinsically Safe, Chemically Resistant Magnetostrictive Float Level Transmitter designed for small-scale liquid level measurement in highly corrosive environments. With an advanced anti-corrosion coating, it withstands sulfuric acid, boric acid, hydrochloric acid, and sodium hydroxide, making it ideal for water treatment, chemical processing, and marine applications.

This hazardous location-approved level transmitter features RS-485 Modbus RTU output, ensuring seamless integration with Modbus controllers. It also pairs with the MDI controller for a fully Intrinsically Safe level monitoring solution. With NEMA 4X/IP65 protection, CSA, ATEX, and IECEx approvals, and a maximum measurable length of 12 ft. 9 in., the MPI-E Chemical delivers high-accuracy, reliable level sensing in the toughest conditions.

  • Safe for Hazardous Locations: Intrinsically Safe for Class I, Div 1, and Zone 0 hazardous locations
  • Chemical Resistant: Chemical-resistant coating withstands corrosive liquids
  • Seamless Integration: RS-485 Modbus RTU output for seamless connectivity
  • Remote Monitoring Capabilities: Compatible with LOE Master and RST-5003 for remote monitoring
  • Accurate Measurements: High-accuracy level measurement with ±0.04 in. resolution
  • Durable Construction: Durable PVDF stem and Kynar float for long-term performance
  • Temperature Rated: Wide operating temperature (-40° to 185°F) and NEMA 4X/IP65 protection
