Echotel® Model 961/962 Ultrasonic Level Switches D E S C R I P T I O N Increasing demands for compliance with safety systems and overfill protection has mandated more reliable point level measurement. Echotel® Models 961 & 962 Ultrasonic Level Switches meet these demands with advanced trans- ducer designs, extensive hazardous location approvals, and a new self-test technology. Model 961 offers the ultimate solution to reliable single point liquid level measurement. This advanced switch uses 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 use in Safety Integrity Level (SIL) 2 loops. Model 962 is a dual point switch that can be used as a level controller, or to control pumps in an auto fill or auto empty mode. The tip sensitive lower gap performs well in aerated or foamy liquids, and can measure to within 1⁄4 " of the vessel bottom. The rigidity of the unique flow-through upper gap allows separations of up to 128" (325 cm) between the upper and lower transducer gaps. F E A T U R E S

P U L S E D S I G N A L T E C H N O L O G Y Cha llenging process conditions such as aeration, suspended solids, and high viscosities are easily handled with the pulsed signaltechnology utilized in the 961/9 62 switches.Pulsed signalcircuitry drives the transmit piezoelectric crystal to produce powerful pulsesof high-frequency ultrasonic energy. These ultrasonicpulses are readilytransmitted through liquids,but are attenuated when the transducer gap isdry.Thistechnology also providesexcellentimm u - nityfrom electrom agneticnoise interference. Pulsed signaltechnology m akes the 961/962 units m ore reliable than older continuous w ave ultrasonicswitches. Un like ma ny tuning forks, pulsed signal ultrasonic switches do notneed to be configured for differentm edia densities,mak ing these units the m ostuniversallyapplied levelsw itches on the m arkettoday. Mod el961/962 switchesutilizeultrasonicenergy todetect thepresence or absence ofliquid ina singleordualpoint transducer.Ultrasoniccontactleveltechnology useshigh- frequency sound waves thatare easilytransmittedacross a transducer gap in the presence of a liquid med ia,but are attenuated when the gap is dry.Mo del 961/962 switches use an ultrasonicfrequency of2 M Hz to perform thisliquid levelmeasurement in a wide varietyofprocess med iaand applicationconditions. The transducerusesa pairofpiezoelectriccrystalsthatare encapsulated in epoxy at the tip of the transducer.The crystalsare made of a ceramicm aterialthat vibrates ata given frequency when subjectedto an appliedvoltage. The transmitcrystalconvertsthe appliedvoltage from the electronicsintoan ultrasonicsignal.When liquidispresent inthegap,thereceivecrystalsensestheultrasonicsignal from the transmitcrystaland convertsitback to an elec - tricalsignal.Thissignalissentto the electronicsto indi - cate the presence of liquidin the transducer gap.When thereisno liquidpresent,the ultrasonicsignalisattenu - atedand is not detectedby thereceivecrystal.

All versions ofthe Mo del961/962 switches undergoa detailed performance evaluation called a FailureM odes,Effectsand Diagnostics A nalysis(FMEDA ).Three key componen ts of the FMEDA are the SafetyIntegrityLevel(SIL),Safe Failure Fraction (SFF)and the average Probability of Failureon Dem and (PFDavg).

M odel 961/962 sw itches feature an advanced self-test technology thatnot onlyteststhe electronics,transducer, and piezoelectriccrystals,but also testsfor the presence of industrialsources of environmentalnoise.Should the switch detectany problems a malfunctionoutputisgen - erated to alarm the user,and a red LED islitto indicate an alarm condition. Self-testisperformed automaticallyand continuously sev - eral times per second to verify proper operation of 961/962 switches.In addition,a pushbutton isprovided to initiatea manual self-testm ode.Pressingthistestbutton stops alltransmitpulses,which simulates an electronics failure.Thisfailureisreportedas:

This tests for electrom agnetic and acoustical noise thatcan influence m any instrumentation technolo - gies.If high levelsof environm entalnoiseare detected, the electronics reports a fault condition to alert the user ofpotentialinstrum entation reliability concerns.
