EchoSpan™ GP Ultrasonic Transmitter, Non-contact Measurement with Display |
|
| Application | The general purpose two-wire ultrasonic transmitter provides non-contact level measurement up to 32.8' or 10m, and is ideally suited for challenging ultrapure, corrosive or waste liquids. Push button calibrated, the transmitter is broadly selected for atmospheric bulk storage, day tank and waste sump applications. Media examples include wastewater and sodium hydroxide. |
| Features | | Setup is fast and simple with push button calibration and LCD display | | Offered in three measurement ranges up to 10m with 2" transducer | | 6-segment LCD display indicates level in inch or centimeter values | | Narrow 3" minimum beam width for applications with restricted space | | PC/ABS enclosure rated NEMA 4X with rugged PVDF transducer | | Fail-safe intelligence with diagnostic feedback for easy troubleshooting |
|
| Configuration | Calibration is fast and simple with our scrolling single layer menu, three button interface and 6-segment LCD display. Troubleshooting is easy with our unique Setup and Diagnostic feedback modes. Setup displays the transmitter's calibration set points. Diagnostics provides users with a snapshot of sensor performance and application variables. Its full feature level made simple.
