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 hygienic process connections. The compact electronics are completely encapsulated just above the process fitting. The Magnetrol ® Model 940 offers a 1-amp SPDT relay output. The Model 941 has a mA current shift output.
Features
- Pulsed electronics for excellent performance in difficult process conditions and superior immunity from sources of electromagnetic noise
- Tip-sensitive transducer gap provides reliable operation by draining viscous liquids and shedding foam in turbulent applications
- Safety Integrity Level (SIL) data (FMEDA analysis) is available. Model 940 is suitable for SIL 2 loops. Model 941 is suitable for SIL 1 loops.
- Extremely compact unit is easily installed in areas where access space is limited
- 1-amp SPDT relay output (940), or mA current shift (941) output
- No calibration required
Application
The Model 940/941 can be applied in a wide variety of high or low liquid level applications, pump protection, and fill line monitoring as shown in the diagram at the left. These compact units can also be installed in the interstitial space between two tank walls for fluid leak detection.
Small size and simplicity of installation make these units ideal for OEM skids as a low cost, yet high performance level measurement solution. They are also the perfect replacement for older floats, conductivity switches, and tuning forks.
