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

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.

Appareillage à basse tension - Partie 5-9: Appareils et éléments de commutation pour circuit de commande - Détecteurs de débit

La présente partie de la CEI 60947 s'applique aux détecteurs de débit qui détectent la vitesse d'écoulement d'un gaz, d'un liquide ou de matière solide granulaire. Ces détecteurs changent l'état de leur sortie si une valeur préréglée du débit est dépassée. Ces détecteurs de débit sont des appareils complets, comprennent des éléments de commutation à semiconducteurs et sont destinés à être connectés à des circuits dont la tension nominale n'excède pas 250 V 50 Hz/60 Hz en courant alternatif ou 300 V en courant continu.

IEC 60947-5-8:2020 specifies requirements for three-position enabling switches. These switches are used as components of enabling devices to provide signals that,
- when activated, allow machine operation to be initiated by a separate start control, and
- when de-activated,
-- initiate a stop function, and
-- prevent initiation of machine operation.
This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- due to the increasing range of useful applications of three-position enabling switches, note of scope, operational characteristics and tests are reviewed;
