Description
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.
Features- 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).
