And give dependable repeatability in the detection of high, low or intermediate loquid levels in almost any tank or vessel. PRINCIPLE A magnet-equipped float the sole moving part moves with liquid level between stops to magnetically actuate a hermetically sealed, glass-enclose HM-95Series 系列液位开关 INTRODUCTION Widely applicable level switch for antioverflow of various liquid tank. Model HM-95 units are siple, reliable float switches designed for top mounting to tanks or vessels. HM-95 units utilize a single switch mechanism and float. PRINCIPLE A permanent magnet is attached to a pivoted switch mechanism. As the float rises following the liquid level, it raises the attraction sleeve into the field of the magnet, which then snaps against the non-magnetic enclosing tube, sctuating the switch mechanism. The enclosing tube provides a static pressure boundary between the switch mechanism and the process. On a falling level, a spring retracts the magnet, deactivating the switch mechanism.
