Sample heater KW5
The sample heater KW5 is connected to the sample line using hose connections as shown in
drawing
KW5-MB
.
The following points must be observed when using the sample heater
KW5
:
The sample heater KW5 ensures that the temperature of the sample in the measuring
cell does not drop below the dew point, thus preventing condensation or fog from dis-
torting the measuring value. The sample is fed through the sample heater and warms
up.
The electrically heated pipe is connected directly to the measuring cell inlet. A socket i n-
stalled on site is required for operation.
5.3.6
Filter KZTN3
When operating without a sample divider (Section 4.2.2), the sample is suctioned in directly
by the suction fan. In order to protect the suction fan, a filter
KZTN3
must be installed up-
stream to filter larger particles out of the sample flow. Insta llation of a filter also prevents
shock waves from spreading from the suction fan into the measuring cell.
The filter is installed between the photometer and suction fan using hose connections. It is
fastened in place using a mounting flange as shown in drawing
KZTN3-MB
.
5.3.7
Suction fan KTNPI/G1 or KZTN2 with motor circuit breaker MSS1
The suction fan inlet is connected to the measuring cell outlet using a hose connection. I n-
stallation is made on an even surface using a mounting flange with horizontal or vertical ro-
tor as shown in drawing
KZTN2-MB
or
KTNPI/G1-MB
.
The following points must be observed when using the suction fan:
A mains supply line is required for operating the suction fan. Actuation is made via the
optional motor circuit breaker MSS1.
The suction fan is usually operated with a motor circuit breaker, which prevents the
motor against overloading. The motor circuit breaker is installed in a protected position
in the cabinet or control box.
