HL 3002

1. HL 3002 1.1 General Sometimes the visibility in the measurement path is poor. The reason for this might be high dust load, smoke or strong ambient light from the process (as in a combustion chamber). In this case a stronger light source must be used in the first alignement step. Siemens Laser Analytics AB can supply a suitable light source labelled HL 3000. This is a point source using a 50 W halogen lamp and will produce a very luminous light spot normally easy to spot in the alignement procedure.

1.2 The alignement procedure The sensor is aligned using the sensor alignment kit AK 3002 together with HL 3000. The aligning procedure is as follows: Receiver side 1. Start by aligning the transmitter side. This is done by removing the receiver at the quick connect interface and instead mount HL 3000 which defines the optical axis of the sensor pair. While the receiver is dismounted - check that the lens is clean on the receiver and that the purging is working.

HL 3000 generates a considerable amount of heat. Protective gloves should be ised when it is handled.

Transmitter side 2. Dismount the transmitter and check that the lens is clean on the transmitter and that the purging is working. Then mount the transmitter and twist-dismount the launcher (fiber cable connector in the middle), twist-mount the cross hair instead. Align with the four bolts on the flange, the light dot must be centred in the inner ring of the cross hair.

Receiver side 4. Mount the receiver back again and twist-mount the cross hair instead of the detector module. Align with the four bolts on the flange, the light dot must be centred in the inner ring of the cross hair.

CD 3002 is now aligned and the holder for the fibre connector and the detector module should be mounted in their places. Finally, instrument air, or which ever method is used to protect the optical surfaces, should be connected to the appropriate inlets both at the transmitter and receiver side of the sensor. The mechanical stability of the sensor mechanics is sufficient to allow dismounting (the quick connection) of both the receiver and the transmitter. This means that cleaning of the lenses does not require re-alignment of the sensor.
