Waterproofing Options for Submersible Installations




Waterproofing Style "A" Series

Suitable For Most Ordinary Submersible Installations when installed with suitable immersion tube (a.k.a. guiderod or standpipe)

Waterproofing Style "B" Series

Suitable For the Most Aggressive Agitated Slurry Solutions & Corrosive Liquids with Complete Cable Isolation With Rugged Tubing Factory Installed

FULLY SUBMERSIBLE ASSEMBLY
WITHOUT IMMERSION TUBE

Waterproofing Style "C" Series

Suitable for Aggressive Agitated Slurry Solutions and Corrosive Liquids with additional sealing compared to "A" Series

Completely Submersible when installed with suitable immersion tube (a.k.a. guiderod or standpipe)

Waterproofing Style "IT" Series

Suitable For Most Submersible Applications & The Most Cost Effective Waterproofing Option

FULLY SUBMERSIBLE ASSEMBLY
WITHOUT IMMERSION TUBE

DOES MY SENSOR NEED A WATERPROOFING OPTION?

  • The sealing on the back of a twist lock and immersion sensors is water resistant, but not waterproof. The standard default isolation on the back of a sensor is a strain relief grommet. This allows for the sensor to be somewhat moved and
    for some minor water exposure without causing sensor failure. For more aggressive water exposure to the back of the sensor, additional precautions must be taken.
  • ASTI sensors are NOT intended to have rain or other continuous exposure of water on the back of the cable without a waterproofing seal installed.

GENERAL COMMENTS ON SELECTION OF WATERPROOFING OPTIONS

  • The waterproofing options offer anywhere from nominal isolation to extremely robust isolation in the following order going from least isolating to most isolating:
  • Most users will only ever require the WPIT, WPA, WPC or WPB options but the WPITC, WPG & WPH versiond with a CPVC material of constructionfor use in the presence of certain oxidizing chemicals are also available.
  • In general, the WPB or WPH sealing is only really required for fully submersible type installations.
    • Note that ONLY the WPIT/WPITC and WPB/WPH waterproofing sealing options provide for COMPLETE cable isolation all the way back to the transmitter.

If you should have any doubt about whether the exact sensor model that you are using is appropriate for the installation style that you are planning to implement, please contact the factory for further assistance!
