Thermoplastic [PVC, CPVC, Polypropylene, or PVDF (Kynar)] Fluid presence sensor. Series FPS to provide low voltage signal and when liquid is present [non-pressurized piping or components]. In the event that the sensing points are damaged by a highly aggressive chemical, the detector section to be easily replaced. FPS to be suitable for any conductive liquid with a resistance less than 3 Megohm. Low DC voltage control wire signals presence of liquid. IP67 DIN Connector with 2M molded cordset included. 1/4" Connection; 1/8" optional for use with Fail-Dry.® All units are to be 100% individually tested at the factory.
