Product Overview
181688BSPP is a RotorFlow® RFS type flow switch. It builds an extra level of reliability and protection into users' equipment. By the principle of operation, the rotor cannot be deceived into indicating a positive flow situation when no flow actually exists. Once set to a desired actuation point, RotorFlow will switch to a “no-flow” condition should the rotor stop for any reason. It protects expensive electronic equipment from coolant flow failure on semiconductor processing equipment, lasers, medical equipment, X-ray and other high-power tubes, and robotic welding equipment.
