Echotel Model 940 and 941 Ultrasonic Level Switches are compact integral units that utilize pulsed signal technology to perform high or low level measurement in a wide variety of liquid applications. These switches feature a 316 stainless steel tip-sensitive transducer that is offered in a variety of NPT, flanged, and sanitary process connections. The compact electronics are completely encapsulated just above the process fitting.
The Model 940 offers a 1-amp SPDT relay output. The Model 941 has a mA current shift output.
Pulsed electronics for excellent performance in difficult process conditions and superior immunity from sources of electromagnetic noise
Advanced transducer design provides reliable operation by draining viscous liquids and ignoring foam in turbulent applications
Suitable for SIL (Safety Integrity Level) 2 loops (FMEDA analysis data available)
Extremely compact unit is easily installed in areas where access space is limited
No calibration or configuration necessary
1 amp SPDT relay output (940), 8/16 mA current shift output (941)
