EIS

Electro-Optic Interstitial Sensor (EIS)

The electro-optic interstitial sensor (EIS) may be used with all EVO™ Series fuel management system ATGs. Utilizing electro-optic technology and made of chemically-resistant polysulfone plastic, the EIS may be installed in sumps, double wall tanks or other locations where the presence of liquid indicates a leak has occurred.

  • Highlights

    • Highly accurate electro-optic technology and closed output circuit ensures that leaks are detected.
    • Chemical-resistant materials.
    • Can be installed in fiberglass or steel double wall tanks.
    • Utilizes light emitting diodes and prisms to indicate if a leak has occurred.

    Approvals/Certifications

    • UL listed.
    • ATEX approved.
    • IECEx approved.

    Application

    For dry tank interstitial monitoring.

    Installation

    Each FMP-EIS comes with 25’ (7.6m) of oil-resistant cable. For fiberglass tanks, FMP-EIS is pulled into the interstitial space using a “fish” string or wire. For steel interstitial tanks, FMP-EIS is lowered directly to the bottom of the interstitial space through a 2” (51mm) NPT fitting provided for that purpose on the tank. Optional installation kits are available which include a riser cap and other parts required to complete installation.
