Echotel® 960 AS-Interface®超声波液位开关

Echotel Model 960 Ultrasonic Level Switches use pulsed signal technology for superior performance in difficult process conditions, and to provide excellent immunity from sources of electrical noise interference. Extensive self-testing of the electronics and transducer make this advanced switch suitable for a wide variety of critical level applications.

Model 960 Switches use Actuator-Sensor-Interface (AS-i) bus digital communications for high or low single point liquid level measurement. AS-i is a versatile, low cost cabling solution that is a digital replacement for traditional hard wiring of field devices. The AS-i bus system provides a digital serial interface with a single unshielded two-wire cable for power and data transfer.

The industrial version of the Model 960 has a cast aluminum electronics housing and a wide variety of threaded or flanged versions of the ultrasonic transducer. The sanitary version is offered in a deep drawn 304 stainless steel housing and transducers with a 20 Ra surface finish.
