Bukh DV20 OIL PRESSURE SENDER

[Hostage]

Good news! FR today confirmed that the sender referred to above (number ends 014) has thread M10 x 1. They have also confirmed previously that the Bukh sender thread is indeed also M10 x 1. So that is the way I will go. I don't plan to fit the new sender until I bring the boat ashore in late Oct. But I m happy that this now concludes this small matter. Hope this is helpful to others.
In closing I also noticed that FR. also appear to sell a Temperature gauge with the thread M14 x 1.5 which I know from experience fits my Bukh. It's in the FR catalogue and the price is about £30 approx. Much cheaper than Bukh at
£65 approx. Food for thought.

Glad you got sorted in the end, and thanks for updating us. (Would be good to receive confirmation it's all working OK once fitted, too.)

Will do. I won't be happy till I know that too!

Just a very short update.
I purchased from Furneau Riddal as stated above in October but it was not fitted until
Feb.
I am happy to report a complete success. There was a Y fitting which contained the
Sender and a switch. I removed the fitting and fitted the new sender/switch direct to the engine. All is now working as desired.
Hope this is of use to some.

Excellent result. Anything that stops Bukh ripping us off has to be a good thing.

Hi there,
do you happen to know the pressure range that the sensor / sender has to deal with? The 5 bar (~ 72.5 psi) sender I installed (purchased that locally from awn.de) seems to oversteer the instrument, i.e., 184+X Ohms sensor reading.
I replaced a mechanical analog instruments which showed a working pressure of < 4 bar (~58 psi). But I am not sure if I can trust that value, it resembled more a 'yes, there likely is something pressing on my membrane' display.

Cheers from the Kiel (Germany) area, and thanks in advance!
