Intrinsically Safe Magnetostrictive Float Level Transmitter

MPI-R

Durable & Accurate for Hazardous Environments

The MPI-R Intrinsically Safe Magnetostrictive Float Level Transmitter offers exceptional accuracy in hazardous environments. The 1.0″∅ MPI-R models are built for extreme durability and reliable performance in tough applications. Designed for Intrinsic Safety, this liquid level sensor provides accurate interface level and total volume measurements. Ideal for use in hazardous locations, it pairs with an Intrinsically Safe Modbus Display (MDI) to form a self-contained monitoring system, eliminating the need for additional barriers.

Durability & Compatibility:

With a robust design that withstands high turbidity and harsh environments, the MPI sensor features multiple stem and float material options, ensuring chemical compatibility and longevity.

  • Low-Level Fuel-Water Interface Detection: Utilizes high-precision technology to accurately detect minimal fuel and water levels, ensuring reliable interface measurement in tanks and industrial systems.
  • Long-Range Performance: Lengths up to 31.5 feet (9.6 m)
  • Large, Buoyant Floats: Ideal for applications where fouling or buildup is a concern, ensuring reliable performance in tough environments
  • Self-Contained Monitoring: Pairs with the Intrinsically Safe Modbus Display (MDI) for easy setup without needing additional barriers.
