Pressure transducers powered by Picoscope 4444 ?

Postby nurber » Tue Sep 05, 2017 4:04 pm

Hi Forum. I'd like to take advantage of the built-in power supply of this scope to power transducers for a pressure application. There seem to be lots of inexpensive transducers ( e.g. Honeywell PX3 ) whose supply is 5VDC with ratiometric output. I should have some DSUB solid contacts for crimping ( i.e. indent crimping ) and the sensors seem to have a slew of connector options ( e.g. Delphi, Deutsch...). Is there anything I need to consider in utilizing these transducers ? Any Picoscope documents on D9 pinouts and suggestions for ensuring the building of a good D9 ?

The power output of the DB9 is normally off and only on if an active probe is connected.

The type of probe is detected by a resistor between pin 3 - 4

the 5.5V output on pin 5 is only on for a TA300 (620 ohm between 3-4)

Thanks for info Benno. Would be nice if Picoscope exposed this PicoConnect ( correct term ? ) stuff including it's control with API so people can create custom/sensors and embedded apps. I'm considering using this scope as the basis for a guided test platform for a particular industry. I think it is perfect for this use particular with the available API. But good power output for sensors and it's programmability is the other key. Of course, it could be perceived as lost revenue if you are the only one making sensors, but the world of Arduino, Raspberry Pi, etc. etc. has shown otherwise.

Hi nurber,

Could you please e-mail support@picotech.com and we can discuss this further?

Thanks,
