Pinout Hyundai excavator pressure sensor wanted

[Hugo Habicht]

Hello,

I am looking for the pinout of those pressure sensors used in Hyundai excavators like the R140 or R210 and others.



Kind regards,
Hugo

signal

Well, I know that.

But I want the pinout, which pin is which signal.

Can you check the wiring diagram for colours of the wires ??

 

[Hugo Habicht]

Well, If I would own one of those excavators it would not be a problem. But I want to buy one of those sensors and use it in my Kubota. It may be protected electronically but I would like to avoid frying the sensor. Hence my question.

And I do not have a wiring diagram. I could not find any freely available service manual on the internet.

 

[GreensvilleJay]

OK, just HOW are you going to use the sensor ? How was it calibrated? does it output a voltage or current when pressure is applied. Is it linear, semilog or log calibrated ? Hmm, is it peizoresistive ???
Without seeing the actual datasheet for that sensor, it may not be 'compatible' with your Kubota.
From the picture it's '50 Bar' so about 725 PSI, so not a primary hydraulic sensor....
The actual easy part is buying the mating connector !

You'd need to find the excavator model that those were used on, then find the wiring diagrams for the excavator, then find the sensor on the diagram.

Never mind, I went and did the work for you.

CD-42/43/44 is a Deutsch DT06-3S-EP06 connector.

Hello Dustball,

that is great, that's what I was looking for, thank you very much !

Where did you find that or which keywords did you use? I did not find anything, only websites asking for a lot of money.

@GreensvilleJay: yes, it is compatible with my Kubota. I built the electronics for the sensor myself and I will calibrate it in software too. I also believe the pressure range is suitable.

Kind regards,
Hugo

nice when a plan comes together !
never thought about the 24 volt battery....
the 1 volt for 0 bar makes sense, as does 5v for 50 bar (full scale)

if you use Olympic averaging of the raw signal, you'll get nice steady numbers.

Nope, only used the free previews.

Yes, on mine too, would not use them. Did not know about previews though, must check again.
