The general purpose optic leak switch provides reliable leak detection in and around secondary containment sumps, tanks and piping systems with a 1A relay output. Media examples include sulfuric acid, water and diesel. The submersible polypropylene liquid leak detection sensor is mounted through the wall or within the interstitial space. The optic leak detection switch is easily placed in the interstitial space of double wall tanks or threaded into a collection trap in secondary containment piping. Ideal for detecting leaks in secondary containment tanks and pipes. Switch fail-safe is "wet" preventing a switch from failing undetected. Useful in many corrosive liquids. Requires small amount of liquid to detect leak. Orientation: universal. Accuracy: +/- 1mm in water. Repeatibility: +/- 0.5mm in water. Supply voltage: 12-36 VDC. Consumption: 25 milliampere maximum.
