Retractable housings InTrac 776/777-SLRetractable housing InTrac-SL – the original –with sensor detector for increased safety.The InTrac-SL range of retractablehousings has been designed tomeet the highest standards ofsafety requirements in modernprocess measurement technology.The housings provide a straightforwardand safe means for insertingand withdrawing measurementsensors, without any need tointerrupt the on-going process.Eight significant benefits:– sensor detector– patented safety immersion tube– various immersion depths to suitreactors, tanks or pipes– process adaption with choiceof Ingold/Mettler-Toledo weld-insockets, flanges or pipes– versions in stainless steelor plastics– manual or pneumatic operation– end-position indicator option forimmersion tube, allowing integrationinto automated processes– possibility of automating sensorcleaning and calibrationThe patented design of the immersion tubeguarantees safe containment of the processmedium during sensor insertion and retractionprocedures.Operator-friendly concept simplifies thetasks of operating personnel.

Retractable housings InTrac 776-SL and InTrac 777-SLSensor change without process interruption;straightforward and safe.For more than 15 years, our range of InTrac retractable housings has beensuccessfully employed in industry around the world to accommodate sensorsfor the in-line measurement of variables, such as pH and ORP, particularly incontinuous processes.Chemical and pharmaceutical process industriesPulp and paper industrySugar processing industryWater and wastewater treatmentDyestuffs and textile industriesMetalworking and electroplating industriesAutomated pH measurement systems generallySuccess factorsThis latest range of high-performanceretractable housings from METTLERTOLEDO fully meets the ever risinglevel of requirements and standardsin today’s process industries. Thehousings have been developed witha special emphasis on safety, versatilityand precision, all adding up tounequalled reliability at a low cost ofownership for industrial users.Sensor change without processinterruptionInTrac retractable housings allowsensors to be easily and safelyinserted into, and withdrawn from,an on-going process without anyoperational interruptions.During a running process, sensorscan be changed, cleaned or calibratedwith a minimum of effort.Enhanced safety immersion tubeThe patented design of the immersiontube guarantees completeseparation of the process mediumfrom the outside environment forall housings with a tube immersiondepth of 100 or 200 mm, independentof position. The safety standardsset for present-day processhousings are therefore fully met byour retractable housings.Automatic calibration or cleaningof sensorsAll housing models are equippedwith a flushing chamber, allowingcleaning or calibration of the installedsensor without interferingwith the running process.These procedures can also be automatedthrough appropriate controlsystems.Choice of process adaptionThe adaption methods available forthe housings include standardflanges, cap nut for Ingold/Mettler-Toledo weld-in sockets, or screw-inconfigurations.Additional functional safetythrough integrated sensor detectorThis innovation prevents insertion ofthe immersion tube into the processif there is no sensor in place.Operator safety and environmentalrequirements are thereby fully respected.Variety of material specificationsAll wetted parts are available in achoice of PVC, PVDF, stainlesssteel or Hastelloy ® C-22 for optimalsuitability of the housing for specificprocess requirements.Manual or pneumatic modesThe InTrac-SL retractable housingsare available for manual or pneumaticoperation.Various immersion depthsFor installation in reactors, tanks orpipes, there is a choice of immersiontubes with lengths of 70,100or 200 mm.
