Re: Data Logger DL1 Mk2, PCB soldering
Just to add there are some fake/cheap Chinese sensors about but the one I got from BHP seemed really good quality and £10 cheaper than buying from RT

I checked them in the temperature chamber at work and both worked well from room temperature up to 120C
Brilliant, thanks for the info. I'm juggling a few things at the mo, but will keep this updated.

UPDATE Data Logger DL1 Mk2, PCB soldering
Right so coming back to this I've got myself a Bosch 0 281 002 412 Temp sender, It has a M14 x 1.5 thread on it so should screw into the zetec sump plug.
Its also got a proper connector to keep the detritus out.
My question to the gang is, what do I use as a 1k ohm pull up resistor? I've looked on mouser and there's all sorts. Thick film, think film, metal film....
Does anyone have an idea on what to get. I only want to do this once so don't mind spending out for a proper resistor. I'm not going to the bay of E for Chinesium ones.

A 1% tolerance thin film resistor should cover your application, 0.25w or higher.

Many thanks
Should I have the resistor closer to the data logger so that the white signal wire is shorter?
I can't see wire length being an issue really but what the typical way of doing it?

Re: Data Logger DL1 Mk2, PCB soldering
That's a tricky one to say, but if you place the resistor close to the dl1 then you will only have 2 wires going all the way to the sensor, if the resistor is close to the sensor then you will have 3 wires that could potentially pick up interference but tbh you're probably only looking at fractions of a degree interference either way.
Oe temp sensor wiring is generally not shielded, or even twisted pair wires, i don't know how the factory dl1 sensor wiring is arranged, but i doubt they do much different.

Re: Data Logger DL1 Mk2, PCB soldering
I've got thousands of spare 1k resistors at work, send me address and I will stick a few in the post
On my dash2 pro setup I put all the pull ups on the back of the dash connector and it works fine plus reduces a few longer wire runs

Brilliant, thanks for confirming my thoughts.

Thanks for the offer. I'll PM you my address.
