流量报警器FA-H-...

Application
The optical flow monitoring unit with light
guides is used in gas analysis on heated
flowmeters with temperatures > 60 °C. The
measuring cones must be transparent.
Thanks to optical scanning, very low flow
quantities can be recorded even in case of
flowmeters with non-metallic or very small (1
mm) floats.
Description
The M&C flow monitoring unit FA1-H-.. consists
of 4 sub-assembly modules:
1. the patented sensor head FA2-H,
2. the 2 light guides FO.. for monostable
function
3. the K-FA-H pre-amplifier
4. the electronic controller FA-1.1 or
FA-1.4**
– ** see data sheet FA-.., K-FA 9.5 –
The sensor head FA2-H is assembled on the
FM1-H flowmeter by means of a pressure
screw with its stationary open prism to the
measuring glass. Assembly is simple and does
not require any disassembly of the flowmeasuring
glass.
The FO1 light guide is supplied with a standard
length of 600 mm. Light guide FO3 (900
mm long) and FO2 (1200 mm long) can be
supplied for greater length requirements.
The angled light-guide ends are fixed into the
FA2-H sensor head with one pressure screw
each. Two light-guides are needed for the
monostable function.
By use of the pre-amplifier K-FA-H a distance
of 200 meters between the flow meter and
the electronic controller FA-1.. (see 9.5) is possible
without problems.
The LED emitters’ light beam passes through
the FO .. light guides and falls upon the
photo-transistor through the FM1-H
flowmeter measuring glass. As soon as the
float breaks the light beam, the photo-transistor
is blacked out. The FA-1.. electronic controller
analyses this changed status accordingly.
By the monostable version a MIN alarm function
in the lowest sensor setting position is
guaranteed.
