27th Edition RHFS Product Guide - Ryan Herco Flow Solutions

OPTICAL LIQUID-SENSING SYSTEMSFEATURES• Optical electronics – no moving parts.• Solid-state reliability.• PFA Teflon and Polysulfone wetted surface probes.• Low-voltage sensing point.• Two-year warranty.APPLICATIONS• The product is used inindustrial, pharmaceutical,high-purity, and aerospaceapplications to controlpumps, valves, alarms,heaters, and auto-cyclingprocesses.These probes detect liquid, using an internal infrared circuit. If the probetip is immersed, light is refracted out into the liquid. If the probe is dry,light is reflected back to a phototransistor.SUBSTITUTES• Fiber Optic probes available,contact your RHFS ServiceCenter for details.765.180.110LEVELITE REMOTE ELECTRO-OPTIC PROBESFEATURES• RHFS stocks two remoteprobes for use with Levelitecontrollers (below).• All materials have 1/2”MNPT on both ends, andcan be easily mounted intoany 1/2” female fitting, orcan be ganged together withstandard 1/2” pipe.• Standard cable length is 25 feet.765.180.140ORDER: REMOTE PROBES, 25 FT.
