Electro-Optic Interstitial Sensor (EIS)
- 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.
- UL listed.
- ATEX approved.
- IECEx approved.
For dry tank interstitial monitoring.
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.
