Restriction gauge

Restriction gauge

(OP)
Guys
I have what I think is a fairly silly question about a restriction guage on an industrial diesel engine.

In the system we use, we have an outer and inner filter assembly leading to a turbocharger. In between there is a restriction indicator which sends a signal back to the engine when the filters are blocked (pressure difference between ambient and inside air intake is great enough)

I think the system works by sensing the deflection of a diaphragm.


Is this correct?
Are there any inherent problems with this system?

RE: Restriction gauge

That's one way to do it.  

A robust example is the Dwyer Magnehelic line of pressure gages/ indicators/ transducers.

RE: Restriction gauge

The problem is that pressure drop is a function of flow which is a function of engine rpm.

RE: Restriction gauge


They are usually looking for maximum vacuum attained.

RE: Restriction gauge

To put it another way, if the pressure drop is not significant, because the engine is not at full power, then it doesn't matter anyway.
