AGF1
WASTE GAS TEMPERATURE SENSOR
PRODUCT DATA
FEATURES
The waste gas temperature sensor AGF1 is suitable for
measuring waste gas in the flue gas pipe.#
The measured waste gas temperature can for instance be
used for the following functions:
• Monitoring of waste gas temperature
• Determining switching on/off times of the burner
• Determining fuel consumption
• Calculating waste gas loss from the heat generator
• Metering the running time of the burner
In order to find out which of the above functions are possible,
consult the instructions of the controller to which the waste
gas sensor is connected.
The AGF 1 is designed as a conduit sensor to measure the
waste gas temperature.

MOUNTING
1. Loosen locking screw B and pull out the sensor element D
from the guiding pipe.
2. Drill a 10 mm Þ hole at the position chosen on the gas
pipe. Take care that the hole for the sensor element is
near the heat generator (ca. 10 – 40 cm behind supports
for the boiler waste gas).
3. Fit the plate C of the waste pipe so that it lies on the pipe.
4. Mark and drill the holes 3.0 mm Þ for the screws supplied.
5. Insert the sensor element into the guiding pipe.
6. Adjustment
The measurement of the waste gas temperature must be
carried out in the core of the waste gas stream (hottest
zone). Furthermore, it must be ensured that the swirling of
waste gas in the pipe has taken place. By inserting the
sensor elelment D at various depths and by repeated
measuring of the waste gas temperature, the hottest zone
will be found. The temperatures can be read in the display
on the digital controller (see instructions).
7. When then hottest zone has been found, the sensor shaft
is fixed into position by tightening the locking screw B.

ELECTRICAL CONNECTION
There is a three-prong connection in the controller.
The wiring of the temperature sensor has to be in accordance
with the overall wiring circuit diagram.

Advantage: only two cables
Disadvantage: the cable resistance RL distorts the

Advantage: the cable resistance is taken into account by
the electronic evaluation and there is no
distorbtion in the measurement.
Disadvantage: three cables are necessary and all must have
the same resistance.
Four cable connection

Advantage: the cable resistance has no bearing on the
results due to the electronic compensation
(current demand and high ohmic voltage
level). The measurement is not distorted and
the cables can have different resistances.
Disadvantage: four cables are necessary
