Does anyone know of on-line wear metal sensors that can be used on diesel engine oil?
I am looking for a sensor for Mine haul trucks.

Dear Tern,
Mostly wear metal test was conducted by Spechtrophotometer Method.
The concept of this method, is to adsorp the emiting light from metal electron. and it will requiring high energy source. I don't think so that online spechtrophotometer for metal analysis is avalaible now for online.
But you may try other method which is Dielectric Stength and Combine it with Magnetic Source. But it will give you the sign of ferro particles only.
I think it is good for Maintenance Use.
If you need further analysis, next you can go to Lab.

Nurudin

Yes I am finding that spectrometer technology is not suitable for real time mobile use, at least at this time. I have found some magnetic inductance technology that sees particles above 50 micron and can differentiate between ferrous and non-ferrous.
Do you have a price point?
Gastops makes something similar to what you are describing originally developed for jet engines. Eaton Tedeco has a conductive screen.
There are magnetic plugs that take the place of your drain plug. Pall filters has a filter with an outer removable mesh but again developed for jet engines. There were some portable systems where you poured oil into cup and gave quantitative measurement of magnetic particles - Robert Lewis I think. Gordon Jones out of Swansea had something similar. Also Kittiwake,Analex, whatever their names are now. One thing to watch is some of the sensors are affected by flow rate. Still comes down to price and matching sensor size capability with the particle size of the severe wear mechanism you want to monitor.

OK, I will look into some of these suggestions, I also found "Impact-tek" offers oil condition and wear particle sensors, although the system would need designed and tested for a diesel engine application. BTW, the failure modes I want to monitor are,
1 - contaminated/deteriorated oil. 2 - reciprocating component failure which leads to engine block destruction (expensive secondary damage)
We do practice a 500 hour oil change policy faithfully and send oil samples to the lab for analysis, but have still had 3 major catastrophic engine failures in a fleet of 15 over a 5 year period for various root causes. 1. a new engine improperly assembled, 2. a 15,000 hr engine, wrist pin failure and 3. oil starvation from dozer laid on its side. Thanks for your input.
