Princo/L2000射频导纳控制器

Description


PRINCO’smodel L2000 radio frequency (RF) point level controller is truly an outstandingvalue. It combines rugged construction, quick, easy installation and all the features you need for years ofeffective, accurate performance. Operating on the RF impedancesensing principle, the L2000 will detect the presence (high level) or absence (lowlevel) of a wide variety of materials. It may be made fail-safe in either highor low mode. It will operate in conjunc-tion with process materials that rangefrom low dielectric (insulating) prod-ucts such as refined oils, to conductiveslurries.The L2000 incorporates Princo’s user-oriented features - reliability,true coating cancellation capability, explosion-proof/weatherproof enclosures,RFI immunity, heavy duty relays, easy-on Teflon/316 SS probes and our unique10-yeqr warranty.The L2000 has everything youneed at a price no higher than the “also rans”.Princo, one of the pioneers of RF levelsensing technology, has provided accurate, dependable, long lived service forthousands of applications in all types of industries, worldwide for more than 4decades.
