The pipe extension is an optional feature that is attached to the 3" NPT SmartBob2 mount and should be used to extend the SmartBob seat through standoff pipes, insulation or other obstructions. The pipe extension keeps the sensor probe from being pulled up into the standpipe, acts as a bushing, and prevents the cable from fraying on sharp objects if the sensor probe should swing while taking a measurement. It also helps keep the sensor probe flush with the top of the bin.
Extension pipes are available in CPVC, galvanized, or stainless steel – with the stainless steel pipe featuring a Teflon cable guide. The pipes are available in custom lengths from 4 inches to 20 feet. A longer extension allows the SmartBob2 remote to be mounted on a catwalk above the vessel and the sensor probe extended down to the vessel top to provide easy access to the remote.
