[dsg-hallb_rtpc] Pressure transducer of RTPC

[Brian Eng]

Hi Jiwan,

The voltage being read back by the cRIO is ~4V which is being converted correctly to ~400 torr.

Can you get the full model number of PT334 so I can better give some suggestions on what you guys could measure to help troubleshoot?

Off-hand some of the things that could be wrong is: the sensor not getting proper supply voltage, a loose connection of the output to the cRIO as it is getting some voltage back, or a bad sensor (let's hope it isn't that as that was the only one we had in that range).

Hello Brian,

RTPC abs. Pressure transducer seems not working properly. This should show around 760 torr (~ 1 atm), but showing about 400 torr only. What could be the reason?

Thank you,
Jiwan
