ok..


oil temp gauge

there are electrical ones and mechanical ones.

which one is more accurate?

i understand the difference, but electrical would be "safer" in the car correct?......


any info on this would he a help..

 

if it's a temp gauge it's gotta be electrical. if you were talking about a gauge that measures pressure, then you'd have a choice between mechanical and electrical. in this sense, mechanical implies running a pressurized line straight up to the gauge itself, which measures the pressure "mechanically" within the gauge. electrical would employ an electrical sender which measures pressure at that point and sends an electric signal to the gauge. so i really don't see how a temp gauge can be mechanical. unless they meant digital and analog?

 

What about your vacuum gauge?

Hehehehe

 

You can get mechanical temp. gauges and they are usually very accurate but a little slow in response and more difficult to install (getting the semi rigid metal line through the firewall is a pain). Electrical temp gauges can be accurate too, but the cheap ones can be way off.
If you are looking at pressure gauges, the same thing goes except that the electrical ones are safer for your engine - no tube from engine to dash to leak out all your oil!

they are both temp gauges

sx7r i agree with you.. that is why i am asking...





i am confuesd... and kev....G stop it.. hehe

 

hmm... interesting, did not know that.

 

The ATM-5747 is the electrical unit. It is a half sweep design, meaning the needle only goes from the 9:00 o'clock position to the 3:00 o'clock position. It is electrical, meaning that is sends and electrical signal to a sender unit that is attached to your fuel line, oil line, etc. It is the easiest to install and setup.

The ATM-5841 is the mechanical unit. It is a full sweep design, meaning the needle goes from about the 7:00 o'clock position to the 4:00 o'clock position. It is mechanical, meaning that you have a t-tap in your oil line, fuel line, etc and you run from that tap a hose that goes through the firewall, to the gauge, then from the gauge back to that tap. It is much more difficult and even more unsafe.

I would highly recommend the ATM-5747 over any other mechanical gauge out there.

 

 

No problem

 

The gages that I never got put in my car were all electrical. I wouldn't consider mechanicals in any passenger car due to having to run fluid lines into the passenger compartment. Not a good idea. You're already using Autometers which is about as good as it gets. Accuracy shouldn't be an issue. I agree with everyone else's advice. Stick with electrical's.
