LPU-2428

Hazardous Locations Meet High Programmability

Made for highly configurable measurement in linear and non-linear tanks and channels, the LPU-2428 can internally calculate distance, level, flow, and volume.

Description

Intelligent and highly configurable. The LPU-2428 can calculate distance, level, flow, and volume in linear and non-linear tanks.

Programmable Intelligence
The LPU-2428 was made with intelligent software for highly configurable measurement. The sensor can calculate distance, level, flow, and volume. In addition, the sensor features a 32-point linearization table for non-linear tanks and channels.

Class 1, Div. 1
This loop powered sensor is suitable for use in hazardous areas rated CSA Class 1, Div. 1.

Maintenance-Free
With a tough, IP65-rated housing, its hazardous rating, and non-contact measurement, the LPU-2428 takes care of itself.

Common Applications
  • CI, D 1 Hazardous Locations
  • Open-channel Flow
  • Non-linear Tanks
  • Dam Tail-water Levels
  • Irrigation Channel Level or Flow
