FF-015RMS-138

Flow Switch FF-015RMS-125/-138 ● Adjusted switching value ● Highly reproducible ● Insensitive to dirt Characteristics The volume flow raises a piston (fitted with a magnet) out from a valve seat against a spring force. The piston actuates a hermetically separated reed switch. Technical data Switch reed switch Process connection male thread 1“-14UNS Adjustment for details see Q table "Adjustment" max.
