INSTALLATION

Installation ofaB12 Transmitterrequiresmechanicallymounting the enclosureand connecting

DC powerto the system.Inaddition, the flowcell assemblyforthe sensormustbe connectedto sample

inlet andoutlet tubing.Hosebarbsaresupplied ontheflowcell,and theinlet and outlet portsaresuitable

fora varietyoffitting with 1/8"NPTconnections.

MECHANICALMOUNTING

The NEMA4Xtransmitterenclosureissurfacemounted usingscrewsinserted throughthe blind

mounting holesaccessiblebyremovingthetransmittercover.Figure5showsthe centertocenter

mounting holedimensionsforthisenclosure. Ifrigidconduitisto be used forwiringthetransmitter,the

transmittercan be supported directlyfromthe conduitsystemwithout the useofmountingscrews.The

transmitterweighsonly4ounces,sonormalconduitsupportswillbe adequate. If conduitistobe used,

be surethat theconduitissealedat the point wereitenters thetransmitter.Otherwise, condensationin

the conduit systemcan drain into the transmittercausing failure ofthe electroniccircuit board.
