APPLICATION
The general purpose ultrasonic transmitter provides continuous level measurement up to 32.8’ (10m) with a 4-20 mA signal output, and is configured via its integral push button display module. This non-contact liquid level sensor is well suited for corrosive, ultrapure, sticky or waste liquids, and is selected for bulk storage, tanker truck and neutralization tank applications.
FEATURES
- Offered in 4 measurement ranges from 9.8’ (3m) to 32.8’ (10m)
- Configuration is simple via integral push button display module
- LCD display indicates level in inches, centimeters and percentages
- Narrow 2” or 3” beam width for applications with limited measurement space
- Fail-safe intelligence and diagnostic feedback for simple troubleshooting
- PVDF transducer and NEMA 4X polycarbonate enclosure for corrosive liquids
- Automatic temperature compensation for accurate measurement
