I'm looking for an analog MR-sensor suitable for harsh conditions. Unfortunatelly, I can only find digital ones. Do you have any suggestions? Were might I find some candidates to choose from?
The North American veriant of Balluff's BTL-5 Ex'd' magnetorestricive sensor has a very heavy stainless steel housing and would be well suited to a harsh environment. It is designed for mounting on a hydraulic actuator with a ring magnet fitted to the actuator rod. The European variant of the same sensor has an aluminium casing and isn't anywhere near as tough.

If we learn from our mistakes I'm getting a great education!
