Use "General Input" for Hydraulic Pressure?

[PhantomPholly]

Hi Dynon,

I was wondering if anyone has used your general inputs for Hydraulic pressure (landing gear) and, if so, what type transducer they used and how it was configured.

If the 3 green lights fail, it would be nice to see that "Up" pressure is zero and "Down" pressure is 550 (Lancair uses 1100 up / 550 down). It would also be nice as a confirmation that the pressure cutoff switches are functioning correctly.

Thanks!

Bump...

Dynon, has anyone hooked up a hydraulic pressure sender to your unit? What would the characteristics of the sender need to be, and how would it be configured?

Thanks!

We have no support for hydraulic pressure senders, nor do we know of anyone that has hooked one up.

Are there hydraulic switches that would do what you want? If it's a simple switch, you could hook it to the EMS contact input. This would only be a yes/no indication though.

There are hydraulic senders that provide a linear / analog signal of voltage up to 10v for a 3000psi sender (best match I have found so far; my hydraulic pump maximum cutoff is SUPPOSED to be 1100psi).

So, it would need to translate a linear scale of voltage from 0-10v into values from 0-3000.

Other senders are fancier, sending customized serial data which would have to be coded for - and they are more expensive, too.
