Type CCB311
Flow Switch
Features and Benefits
• Suitable for liquids or gases to meet Customers’-
requirements
• Low pressure allows switch to be placed in many
locations without increasing pressure loss
• Certified explosion-proof or intrinsically safe
Description
The flow switch CCB 311 is designed to detect low flows
in horizontal or vertical pipes with an upward flow direction.
The type CCB 311 flow switch is very robust with high
repeatability and a very basic design.
An articulated flap placed perpendicular to the flow,
moves according to the flow changes. An extemal reed
switch is activated by the magnet installed on the flap.
(The magnet is protected from corrosive medium by a
stainless steel jacket) An external housing contains the
reed switch and connection terminal block for wiring.
Construction
This flow switch consists of:
• A stainless steel 316L body
• A stainless steel 316L flap
• A stainless steel 316L diaphragm
• The connection is made by stainless steel fixed flanges
(Standard ISO PN NF EN1092 or ANSI B16-5)
• Alarm contacts
