JamesH- Ive found a 3mm o/d probe that's made of Inconel the other probes ive looked at don't mention material. From my design days its seems unlikely Inconel will fail through Vibration am I correct on that.
Im also looking at a Kronenburg Management Systems EGT-CAN converter its not the best but perhaps the best compromise. Rang Datron today there 8 channel unit is £2500+ vat
that will be a No then
. They also do a 4 channel for £1500+ vat it looks like the KMS & quotes a similar spec. who pays those prices. If you have not heard they are shite or a bunch of bandits think my money will go with KMS.
