AST10 and AST51
AST10 & AST51
The AST10 and 51 sensors offer a compact design that allows installation into standard pipe fittings in small line sizes such as 3/4″ and 1″, avoiding the need for special flow cells. Simplicity of the design also allows them to be economically offered in exotic metals for especially corrosive chemical applications.
Application Notes
Wetted materials of construction are 316 stainless steel and Teflon, with double o-ring seals at all points. The outer EPDM o-ring bears the brunt of process interface, allowing the back o-ring to maintain reliable sealing free from chemical attack. An integral temperature element tailored to the analyzer of choice allows automatic compensation for maximum accuracy. Leads are 10′ standard, stripped and tinned ends or optional spade lugs. Small size enables
convenient installation and service O-ring seals used on all versions for high on-stream reliability
Plastic gland fitting allows removal and replacement without tools Process connections are made via a bored through swage fitting with 1/2″ or 3/4″ NPT
threads. This fitting can be screwed into a line, or tank, and it can also be turned around and connected to a standpipe for use in a submersion configuration. The AST51 is good for general purpose use up to about 20,000 micromhos on most analyzers, while the AST10 covers a broader range of cell constants and therefore of conductivities.
