Waterproofings are an optional feature which allows ASTI to excel in hazardous and/or corrosive environments.  The excellent sealing offer by our three major series of waterproofing/sealing assemblies ensures that the our sensors will not be prematurely killed by chemical or mechanical attack from the rear end of a submersed sensor.

Suitable For Most Ordinary Completely Submersible Installations

Option Available For:

• 3/4" MNPT Rear Threaded Immersion Sensors (6X11, 6X12, 6X32 & 6X42 Series Sensors)
• 1" MNPT Rear Threaded Immersion Sensors (6X31, 6X41 Series Sensors)
• 1" MNPT Read Threaded Twist Lock Sensors w/ guard added to front end (8X31 Sensor Series)
• 1 1/4" MNPT Read Threaded Immersion Sensors - AB 6100 Fluoride Sensors and other special orders sensors with 1 1/4" MNPT Rear Threadings

Features & Recommended Applications: 

• Complete isolation of back end threaded fitting from liquid process and good protection of cable from corrosion and chemical attack
• Rear threading is identical to that specified on original sensor specifications prior to application of Waterproofing "A" Option
• Hex Head for wrench flats enable easy installations into fixtures
• Not recommended for extremely corrosive installations or installations which do not utilizes any kind of guide rod or conduit
• Recommended primarily for elongating sensor life where attack of liquid from back end causes death to sensor prior to chemical or physical attack through front of probe

• For Applications requiring Waterproofing Assemblies to be suited for solvent extraction (kerosene and other heavy hydrocarbons) or solvents/organic media containing solutions; Change Waterproofing Description from Waterproofing "A" to "D"
• For Applications Requiring Waterproofing Assemblies to be constructed of only CPVC (for strong oxidative or reducing solutions - i.e. chlorine, chlorine dioxide, strong hydrogen peroxide or ozone solutions... etc.); Change Waterproofing part description from Waterproofing "A" to "G"
• For Applications requiring Waterproofing Assemblies to be suited for both solvent extraction (kerosene and other heavy hydrocarbons) or solvents/organic media containing solutions and to be constructed of only CPVC (for strong oxidative or reducing solutions - i.e. chlorine, chlorine dioxide, strong hydrogen peroxide or ozone solution... etc.); Change Waterproofing Description from Waterproofing "A" to "J"
