Interstitial Leak Detection Switch Max. pressure: 50 psi Temp. range: -40 to 221FProvides a leak detection system in and around secondary containment tanks and sumps. Switch can be horizontally mounted on a tank wall or bottom of sump. Flat profile and minimal float rise allow mounting in tight spaces. Normally closed switch opens to alert when liquid is detected. Contact type is 30W, 240VAC (0.14A resistive), 120VAC (0.28A resistive), 120VDC (0.07A resistive), 24VDC (0.28A resistive). 2-conductor, 22 AWG wire. Switch is foamed polypropylene, Valox 420, and stainless steel with Halar jacket to resist corrosive liquids.UL Listed and CE Certified.Features:Output-SPST ReedTemp. Range--40 to 221 Degrees FMax.
