The APG LPU-2428 Level Sensor is a loop-powered ultrasonic level sensor with a range from 1 to 25 feet and Class 1, Div 1 certification. The LPU-2428 is designed 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.

The LPU-24287 provides continuous level/distance measurements that are accurate to ±0.25% of detected range. Its durability, range, and simplicity make it a great sensor for many applications. With CSA hazardous location certification, and a durable housing with high chemical compatibility, the LPU-2428 ultrasonic sensor performs well under stress.
