IL55 and IL55BV2 Sensor Instruction Manual
5.1 Sensor Removal
The IL55 can only removed once the pipeline is de-pressurized and drained. Care must be taken to ensure that it is
safe to remove the sensor before carrying out the procedure below:
1. Loosen the knurled ring
2. Ensure that there is sufficient free cable to allow the sensor to be removed
3. Undo the knurled ring, do rotate the sensor whilst doing this as damage could be caused to the internal cables
4. Remove the sensor from the pipeline.
5. Ensure that the optical surface is protected while out of the pipe.
