The 'ASM' Series Load Monitoring Switches from NK Technologies are designed for overload, underload or operating window applications.  Upon sensing an average operating current, the ASM selflearns and establishes a limit-alarm trip point based on +/- 15% of the average expected current draw. The ASM offers a choice of solid state outputs and is available in solid or split-core enclosure styles.

        Interlocks multiple conveyor sections.
     • Electronic Proof of Flow (-UL option)
        More reliable than electro-mechanical pressure or flow switches. No need for pipe or duct penetrations.
