AM Series Stainless Steel Conductivity Cells
AM3422 - variable insertion with PVDF or Stainless Steel compression fitting
The AM3422 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.
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.
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 AM3422 is good for general purpose and covers a broader range of conductivities.
AM3444 - boiler/condensate (high temperature) construction
The Model AM3444 sensor was designed for high pressure, high temperature conductivity measurements, and is an ideal choice for boiler control applications. Blowdown control,condensate monitoring, leak detection on heat exchangers, and steam purity measurements are just a few of the many applications in which this rugged and reliable sensor can be used.
Wetted materials of construction are 316 stainless steel, PEEK, and EPDM o-rings. All possible leak paths through the sensor are double sealed with o-rings for maximum on-stream reliability. Hot water is a severe environment for any elastomer, and the front seals bear the brunt of chemical attack, allowing the back seals to remain relatively unaffected. The result is that sensor life.
AM3455 - sanitary flange fitting
The AM3455 sensors are welded to blind flanges and can be inserted into standard tee fittings in sanitary systems using Ladish or Tri-Clover fittings.
Wetted materials of construction are 316L stainless steel and Teflon, with double redundant EPDM o-rings. The process side or-ring is the only one in contact with the stream, allowing the back o-ring to maintain reliable sealing, free from chemical attack. Temperature compensation elements are potted in the body itself. Leads are 10 standard.
Process connections are Tri-Clamp sanitary flanges of customer specified size. The insertion depth can be modified on request to obtain proper positioning in a specific installation. The sensor is built for clean in-place service, either stream or sterilizing chemicals. All wetted materials are FDA compliant and USP Class VI is available.
