Gems RFS Series [155425] Flow Switch Polypropylene 24 VDC 0.25in NPT

The Gems RFS series flow switch builds an extra level of reliability and protection into your equipment. Combining visual confirmation of flow with dynamic, electronic switch operation, the RFS series cannot be deceived into indicating a positive flow situation when no flow actually exists. Once set to a desired actuation point, the RFS will switch to a "no-flow" condition should the rotor stop for any reason. The RFS series has easy, adjustable switch point calibration making it the ideal instrument to protect expensive electronic equipment from coolant flow failure.

The RFS series has port sizes from 1/4" to 1" NPTF for liquid flow settings from 0.10 to 60 GPM. Featuring rugged brass, stainless steel or polypropylene construction, the RFS utilizes a simple and reliable design suitable for operating temperatures to 212°F and line pressures to 200 psig.

Applications for the Gems RFS Series flow switch:

• Semiconductor Processing Equipment
  
• Lasers
  
• Medical Equipment
  
• X-Ray and Other High Power Tubes
  
• Robotic Welding Equipment
