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:

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
