Oil Pressure gauges, mechanical or electric

Recommended Posts

I have a mechanical Smiths one on my Tdi 109.   I am not convinced about its accuracy, though I don’t think it’s far off, but it does get a tiny amount of oil vapour inside the gauge, presumably from a tiny leak somewhere internally.  The real concern is that a rupture could cause a stream of hot oil into the cab, posing a real injury risk, not just making a big mess.  That can’t happen on an electrical gauge.  Routing a wire is also easier than routing a capillary tube.

This is @JeffR asking . We don't want him to come to harm. If he goes mechanical how long before an incident involving hot oil being sqirted at his nether regions? ( or similar, you know how it goes)

True - but if anyone can electrocute himself installing a 12V gauge...

I take your point. I wonder what other types of gauges there are...
