Induction sensor - installed in solid iron
(OP)
Hi,
Do induction sensors work when surrounded by iron?
Let's say I have a large block of iron that has a long hole (8mm in diameter) going through it. An induction sensor is placed midway through the hole, and then a solid iron cylinder (8mm in diameter) is inserted from the opposit end of the hole and placed adjacent to the sensor. Will the sensor be able to measure the distance between itself and the cylinder, or will the surrounding material render that impossible?

Infrared may be a better choice for this, ultrasonic if it's too dirty for optics.

The sensor I'm currently considering has a fairly linear respons ranging from 0-5V, in the distance interval 0-4mm. Based on Skogsgurra's (jag kanske hör av mig dig senare. Lägger gke på minnet i alla fall) post I assume that the output range will be diminished due to the massive surrounding material, and perhaps rather nonlinear. This will reduce the accuracy of the distance measurment, but that might be OK.
Regarding the sensing interval. Should I expect any changes in particular? A longer, shorter or perhaps a translated (3-7mm for instance) range?
Jraef, I've thought about using light and sonic sensors, but the working environment is harsh (water, mudd, oil, -30C°, machanical impacts, mechanical wear) and I believe that rules out such sensors. Please let me know if that is not a valid conclution.
