Hazardous Locations Meet High Programmability
Made for highly configurable measurement in linear and non-linear tanks and channels, the LPU-2428 ultrasonic transmitter can internally calculate distance, level, flow, and volume.
Intelligent and highly configurable. The LPU-2428 ultrasonic transmitter can calculate distance, level, flow, and volume in linear and non-linear tanks.
The LPU-2428 was made with intelligent software for highly configurable measurement. The intrinsically safe ultrasonic 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 intrinsically safe ultrasonic sensor is suitable for use in hazardous areas rated CSA Class 1, Div. 1.
With a tough, IP65-rated housing, its hazardous rating, and non-contact measurement, the LPU-2428 takes care of itself.
