2.1 The Rosemount 3101, 3102, and 3105
The 3101, 3102, and 3105 are 4–20 mA loop-powered level transmitters designed for
continuous liquid level measurements in tanks or open channel flows.
The transmitters can be connected directly to a plant control system, or used with a Rosemount
3490 Series Control Unit for programmable control functionality. The Rosemount 3105 may be
mounted in a hazardous area if powered from a protected power supply.
