Title: Placement of temp and pressure sender Post by: Jesse/DVK on September 17, 2016, 15:22:30 pm Hi guys,
For my project '67 i'm looking at the placement of the temperature and pressure sender. I was thinking of putting them both in the rear fenderwell where the oil filter will be located.The temp sender I want to locate in the oil filter adapter. The pressure sender I want to use this style fitting so the sender can be screwed on this. (http://www.jegs.com/images/photos/300/361/361-100201.jpg) Would this be a good location to measure temp and pressure? I think the senders etc will be ok for any waterspray if I would drive in the rain.

Are you trying to keep the engine bay 'clean' of fittings/sender?

Temp in the sump. Title: Re: Placement of temp and pressure sender Post by: richie on September 17, 2016, 18:41:33 pm Hi Jesse,
I have pretty much what you describe on both white 67 and old cabrio & works well, only thing that may affect it is if you got remote oil cooler after filter? with what you describe you will measure hot oil from sump rather than what bearings will see if you are using extra cooler. I don't worry about this to much as just use temp as a guide to what is going on rather than as actual temp. I use mechanical oil pressure gauge rather than electric as its more reliable and gives better reading cheers Richie Title: Re: Placement of temp and pressure sender Post by: Jesse/DVK on September 18, 2016, 09:04:50 am Hi Jesse, I have pretty much what you describe on both white 67 and old cabrio & works well, only thing that may affect it is if you got remote oil cooler after filter? with what you describe you will measure hot oil from sump rather than what bearings will see if you are using extra cooler.

So I will measure the temperature of the oil going to the engine.

I use mechanical oil pressure gauge rather than electric as its more reliable and gives better reading cheers Richie i have a temperature sensor on top of the oilfilter, that has worked for me for years. and yes it does measure the temp when hot, but it also is a indication of the oil getting hotter. and like Richie pointed out. these measurements are in a lot of cases just a 'gestimate' or 'educated guess'. i know what mine needs to read to be OK. i have learned it from years using the same gauge. but i would rather rely on oilpressure if i had to chose one above the other. it is electrical and the same applies, you have to learn to see what it does. i have never fitted a mechanical one, so i can't comment on that. |
