APG - Model Series LPU-2428 -Intrinsically Safe Ultrasonic Level Transmitter with 4-20 mA Output
Hazardous Locations Meet High Programmability. Intelligent and highly configurable. The LPU-2428 can calculate distance, level, flow, and volume in linear and non-linear tanks. Range: Up to 25 ft. Mount: 2 in. NPT. Output: 4-20 mA. Certification: CSA, Class 1, Div 1, Class 1, Div 2, Intrinsically Safe.
With Class 1 Division 1 ratings, the loop powered LPU-2428 is built to handle the most hazardous locations. Add the ability to internally calculate volume or open channel flow data, and you have a unique and powerful ultrasonic sensor.
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.
