Metritape™ Hastelloy Level Sensors LA-HN and LA-HP • Hastelloy construction provides excellent chemical compatibility • Proprietary laser welding process delivers years of service in demanding environments • All electric resistance-tape sensor for stable output; no moving parts to stick or break • Tank top mounted for easy installation • Virtually maintenance-free • Intrinsically safe • Can combine level and temperature capability in a single sensor • Wide operating temperature range The LA-HN and LA-HP level sensors are used to gauge petroleum products and many chemicals with The LA-HN and LA-HP level sensors are available in overall lengths of 1 to 36 meters (3 to 120 feet). Both models have a high resolution helix and gold-on-gold electric contacts for 5 mm (1/4") turns resolution and long-term contact stability. The LA-HN is enclosed in a Nylon 12 channel for physical protection (LA-HP is enclosed in a polypropylene channel). The filter assembly protects the sensor from moisture and contaminants and provides pressure equalization. Optional temperature detection can be included in either model with up to three (3) RTD detectors mounted within the sensor envelope at specified Models LA-HN and LA-HP may not be suited for use in some chemicals, caustics, high vapor-pressure materials, or under cryogenic or high level nuclear radiation conditions. Check factory for details.

Metritape™ Hastelloy Level Sensors LA-HN and LA-HP Operation Principle: outer envelope jacket (1), is pressure causing the gold plated nichrome wire helix to contact the stainless steel base strip indicates the length of active or tance from sensor top to liquid The LA-HN and LA-HP sensors are installed into a customer supplied, vented stillpipe with a minimum interior diameter of 40 mm (1.55 inches). Specific stillpipe construction may vary with application. To Specify Length - (1) Select stillpipe in feet or meters; (2) Specify LA-HN or LA-HP sensor of same length as stillpipe; (3) LS =...
