## Description

Flow Set Point Switching - RFS Types. Combines visual confirmation of flow with dynamic, electronic switch operation. Easy, adjustable switch point calibration: a local LED signals when set point is reached. RotorFlow Switches build an extra level of reliability and protection into your equipment. By 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. Typical Applications: Protect expensive electronic equipment from coolant flow failure on Semiconductor Processing Equipment, Lasers, Medical Equipment, X-Ray and Other High Power Tubes, Robotic Welding Equipment.

## Features

- Wetted Materials: Polypropylene, Ceramic, PPS Composite, Polysulfone, Buna N (Low Flow Adapter - Polyproylene)     Electrical Termination: 20 AWG, 24"-26" PVC Leads     Switch Type: SPDT (1A - 24VDC, 1/3 A - 110VAC)     Set Point Differential (Maximum): 0.15     Recommended Filtration: 150 micron
