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.

Niederspannungsschaltgeräte - Teil 5-9: Steuergeräte und Schaltelemente - Durchflussmengenschalter

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.

This European Standard was approved by CENELEC on 2007-09-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

Foreword
The text of document 17B/1500/FDIS, future edition 1 of IEC 60947-5-9, prepared by SC 17B,
Low-voltage switchgear and controlgear, of IEC TC 17, Switchgear and controlgear, was submitted to the
IEC-CENELEC parallel vote and was approved by CENELEC as EN 60947-5-9 on 2007-09-01.
This standard is to be used in conjunction with EN 60947-1:2004 and EN 60947-5-2:1998.
The provisions of the general rules, EN 60947-1, are applicable to this part of EN 60947, where
specifically called for. General rules clauses and subclauses thus applicable, as well as tables, figures
and annexes are identified by a reference to IEC 60947-1, for example 1.2.3 or Annex A of IEC 60947-1.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-06-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-09-01
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of
EC Directive EMC (2004/108/EC). See Annex ZZ.
Annexes ZA and ZZ have been added by CENELEC.
