Echote l® Models 960/961 U ltrasonicLevelSwitches forHygienicApplications D E S C R I P T I O N Echotel ® M odel 960/961 U ltrasonic Level Sw itchesuse pulsed signal technology for superior performance in difficult process conditions, and to provide excellent imm unity from sources of electricalnoise interference. Extensive self-testingof the electronics and transducer m ake this advanced switchsuitablefora wide varietyof hygieniclevelswitchapplications. M odel 960 Sw itches use A S-Interface ® (AS-i)bus digital comm unicationsforhigh or low singlepointliquid level measurement.The AS -ibus system providesa digitalserial interface w ith a single unshielded two-wire cable for power and data transfer. M odel961 isofferedwith either a 5-amp relayor a cur - rent shift electronics.The relay output electronicshas a DPDT relayforleveldetection,and a SPDT m alfunction relay.The currentshiftversion indicates 8 m A duringnor - m al operation,16 mA as a level alarm condition and a user-selectable 3.6 or 22 mA m alfunction indication. The 960/961 switches are designed for the stringent requirements ofhygienic applications.These switches are offeredw itha deep-drawn 304 stainlesssteelhousingthat isfavorable to CIP and SIP procedures.A 20 R a surface finish isfeatured w ithhygienicMod el960/961 transducers. These transducers are available with 1 1⁄2" & 2" Tri-Clamp ® fittings,and DN65 Varivent ® Type N flanges. F E A T U R E S

Mode l9 60/96 1 switches use pulsed signal technology to detect the presence or absence of liquid in an ultrasonictrans - ducer gap. The transducer uses a pairof piezoelectric crystals that vibrate at a given frequency w hen subjected to an appliedvoltage. The transmitcrystalconvertstheappliedvoltagefrom the electronicsintoan ultrasonicsignal.When liquidispresent inthe gap,thereceivecrystalsenses theultrasonicsignal and convertsitback intoan electricalsignal.Thissignalis sentto the electronics to indicate a wet gap condition. When no liquidispresent,the ultrasonicsignalisattenu - ated and isnot detectedby thereceivecrystal . Challenging process conditions like aeration, suspended solids,and high viscositiesare overcome by using pulsed sig - nalcircuitry in96 0/961 switches.Un like many tuning forks, pulsedsignalultrasonicswitches do not need to be config - ured for different media densities,making these unitsthe mo stuniversally appliedlevelswitches on themarkey today. Ultrasonic transducer Transmit□ crystal Receive crystal Ultrasonic signal transmission□ across transducer gap P U L S E D S I G N A L T E C H N O L O G Y A D V A N C E D S E L F - T E S T A N D D I A G N O S T I C S Ultrasonicswitches are often used as the last m eans of detecting whe ther a processvesselw illoverflow and cause a spillof potentially hazardous liquids,or empty out and possibly cavitate the pump s.In thesecriticalapplications itis desirable to have a method of periodicallytesting the ultrasonic switch toensurethatitis functioning properly. Mod el 96 0/961 switches feature an advanced self-test technology thatnot only teststhe electronics,transducer, and piezoelectric crystals,but also tests for the presence of industrialsources of environmental noise.Should the switchdetectany problems a m alfunction outputis gen - erated to alarm the user,and a red LED islitto indicate an alarm condition. A microprocessor inthe 960/ 961 electronics continuously m onitors allself-testdata.Shoulda faultoccur,the micro - processor can determine w hether the malfunction isdue tothe electronics,transducer,piezoelectriccrystals,orthe presence ofenvironm entalnoise.A pushbutton and Fault LED is used to assistintroubleshooting the switch:

55 Tw o flashes ofthe FaultLED indicates a

problem with one ofthe electronicsboards

555 Three flashes ofthe FaultLED indicates

excessive levelsofenvironm entalnoise Transducer & crystals Electronics Noise A D J U S T A B L E T I M E D E L A Y Turbulence and splashing can cause some fixed time response switches to produce false level alarms . Model 960/ 9 61 switches overcome this difficulty with an adjustable time delay feature. A potentiom eter allows a 1⁄2 –45-second delayto be setto disregard w aves or splashes,and reliablydetectthe true liquidlevel.
