Electro-Optic Interstitial Sensor (EIS)

Electro-Optic Interstitial

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.

  • 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.

Applications

  • For dry tank interstitial monitoring.

Installation

Each EIS comes with 25' of oil-resistant cable. For fiberglass tanks, the EIS is pulled into the interstitial space using a “fish” string or wire. For steel interstitial tanks, the EIS is lowered directly to the bottom of the interstitial space through a 2" 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
