Probe retractor
The probe retractor moves the up to 3.5 m long gas sampling probe. The drive
is a pneumatic chain drive.
The following illustration shows the probe retractor:
The main components of the probe retractor are:
No.
Component
Function
1
Pneumatic box
Central monitoring device to
control compressed-air supply
2
EMERGENCY-STOP switch
Interrupts movement of the gas
sampling probe.
3
Pneumatic motor
Ensures movement of the probe
retractor.
4
Terminal box
Electric current connection.
5
Heated connection box
("cable drag chain")
Connection between the sample
gas line of the gas sampling
system and the downline sample
gas line of the gas analysis sys-
tem.
6
Shutter
(with automatic [pneumat-
ic] or manual actuation)
Closes the kiln duct opening
when the probe is retracted.
not
illustrated
Transport supports For safe transport / storage of
the retractor (removed in opera-
tion).
7
Gas sampling probe
For sampling sample gas.
8
Heated sample gas line Transports the sample gas from
the probe to the downline sam-
ple gas analysis system. Heating
function prevents condensation
from building up.
9
Warning lamps Warn about insertion and retrac-
tion movements of the gas sam-
pling probe.
10
Energy chain Guides pneumatic lines and
electrical cables and the heated
sample gas line and cooling
water tubes.
