Description
The M-50X explosion proof fixed flow switch monitors increasing and decreasing flow. It utilizes a single moving part which responds to fluid (liquid or gas) flowing within a system. The switch is suitable for a wide range of applications in industrial, biomedical and OEM products. The flow monitors operate only when fluid flows is absolutely established.
The operating principle is based on a free floating magnetic piston which responds only to the motion of fluids within the line, not to static or system pressures. In the presence of fluid flow, controlled movement of the piston actuates an external hermetically sealed reed switch thus opening or closing the required signal circuit. This signal can be used to actuate audible or visual alarms as well as relays, or other controls. Piston travel is short which insures low hysteresis. Pressure drop across flow switch varies from 0.035 to 2 psi (at maximum flow rates for air and liquid). Universal mounted units are outfitted with a spring which resets the piston. The spring is held in place using a perforated disc.
