Rosemount™ 2501 Solids Level Switch - Rotating Paddle

Solids level switch that withstands heavy loads and extreme temperatures, with self-diagnostics, adjustable switching delay, unaffected by dust/grain size/caking

The Rosemount 2501 Solids Level Switch withstands heavy loads and extreme temperatures, and is suitable for full, demand or empty detection for all bulk media in all types of vessel. It is a simple, robust and reliable technology that is insensitive to dust, electrical charge, adhesion, extreme temperature and pressure. It is simple to install and can be mounted in a vertical, horizontal or oblique position.

Key Features

  • Reliable Detection Across All Solids: Handles all bulk solids media, from light powders to coarse and heavy particles, regardless of particle size.
  • Mechanically Stable Bearing for Long Service Life: Stable shaft‑bearing construction maintains smooth rotation and dependable switching, even under continuous solids contact.
  • Unaffected by Dust, Caking or Electrostatic Charging: Performs consistently in dusty, sticky or humidity‑prone processes without false trips or maintenance interruptions.​
  • Fast and Flexible Installation: Simple mechanical setup with no configuration needed, reducing commissioning time and complexity. It can be mounted in a vertical, horizontal or oblique position.​
  • Robust Design for Extreme Conditions: The rotary paddle design withstands heavy loads and extreme temperatures
  • Wide Range of Connections and Voltage Options: Multiple process connections and supply voltages support easy integration into new or existing solids‑handling systems.
