Stack ST747 pressure sensor

Hi - I'm looking for a solid state fluid pressure sensor to for fuel pressure - the Stack ST747 *seems* to fit the bill - but I can't find a great deal of technical info on it.

Can anyone advice as to whether or not it'd be compatible with the S6plus?

Cheers,

Ed.

As long as it's a 5v powered 0-5v out then no reason why not.

What's difference between it and the likes of this ?

Well, comparing the spec of the Stack vs. the KA sensor that we sell:
  • The stack is less accurate (2% vs 0.5%)
  • has a lower maximum working temperature (120 vs 130)
  • has a slightly better minimum working temperature (-30 vs -20)
  • has a poorer IP rating (IP65 vs IP67)
  • has a slightly less common connector (mini sure seal vs. Metripack 150)
  • doesn't state if the seals are OK in the presence of methanol/ethanol - the KA is fine.
  • is, I imagine, more expensive!
It does, indeed, have a 0.5-4.5V ratiometric output so will certainly do the job.

There are many pressure sensor out there with a superficially similar spec - I have sold 100's and 100's of the KA 10 bar sensor and only ever had one fail, due to excessive vibration as it was mounted direct to the block of a 1970's Lotus engine.
