Electro-Optic Interstitial

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.

Electro-Optic Interstitial Sensor

• 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.
• Each EIS comes with 25' (7.6 m) 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.
