Using Bosch dual sensors

I am nearly complete refreshing my build and while perusing through the Bosch motorsports catalog I notice they have dual (temp and pressure) sensors.

Thinking to my self this would save space and reduce the number of holes in any system.
Bad part is if half the sensor goes down you'll have to replace the unit.

The wiring is simple enough and I imagine you could bench test the sensor to get numbers vs voltage/resistance in case Bosch doesn't have data sheets to go with the part.


Has anyone used these sensors in their build?

Here's a link for anyone else who might be curious.

(THERE ARE DIFFERENT VARIANTS IF YOU SCROLL DOWN AND LOOK IN THE LOWER RIGHT HAND CORNER)

Thanks,

Brucebruce

interesting... the sensor would be a simple way to get oil pressure and temp... being Bosch, i would bet it would have a very low failure incidence. the temp is limited to 150 C or 302 F which would be fine...

I found a site that sells the sensor in the UK. In the product description it states will come with a document of specifications. So, to better helping us to tune.

Provided is a link below:

Looks good! But curious about those metric threads? Checking Google, I couldn't easily find a suitable BSPT/NPT fitting to suit M8 or M10 sensor threads.

While a 2-in-1 oil temp/pressure sensor may clean up your installation and make it prettier, I personally see no real advantage to using one - better off with individual sensors in the long run. Rationale is that if either of these 2-in-1 sensor elements fail (and it will eventually), it may be difficult to find a drop-in replacement sensor, especially if you need one in a hurry. This is kind of a niche product, so there's some risk that it will be out of production when you need a replacement, and there probably won't be a compatible drop-in replacement available from an alternate vendor. Going with individual temp & pressure sensors, of which there are many standard types to chose from, made by multiple vendors means that future replacement parts are easier to find & quicker to deliver.
