SwitchGear/ControlGear

Semiconductor Device Standards also cover devices outside of those large series. Smaller IEC series and those from other standards developing organizations provide further information about other devices using semiconductors, such as HVDC systems, switchgear/controlgear, X-ray machines, fiber optics, and others.

IEC 60947-5-9 Ed. 1.0 b:2006

Low-voltage switchgear and controlgear - Part 5-9: Control circuit devices and switching elements - Flow rate switches

"This part of IEC 60947 applies to flow rate switches that sense the rate of flow of a gas, a liquid or a granular solid. These switches change their output state if a pre-set value for the speed of flow is exceeded. These flow rate switches are self-contained, have semiconductor switching element(s) and are intended to be connected to circuits, the rated voltage of which does not exceed 250 V 50 Hz/60 Hz a.c. or 300 V d.c.
