Good day to all,

I am looking for the pressure transducer on the sensor valve PCB. Can someone help me with the number on the sensor, as there is no indication on it to get a replacement. (Viasys - Infant Flow SiPAP)  Anyone perhaps have a circuit diagram? 

Kind regards Kobus

Good morning, everyone. I am having a problem with the power supply card, which is 220V AC to 28V DC, the battery manager, and the 24V output regulator card, so I need the schematics to fix the fault in these circuits. I have had difficulty finding them. Thank you so much.

We have a PB980 that keeps getting a "low measured O2%" error. We did a PM on it about a month ago and it passed the EST and SST, within a couple of days of the PM the respiratory department put in a work order saying they were getting the error. We checked it out and it will run fine in a test setting but as soon as they set it up for use it gets that error. I replaced the O2 cell again just to be sure it wasn't a bad O2 cell and then had them run it with a test lung, it ran fine. We re-ran the EST and SST, it passed both but as soon as they put it in patient use they started getting the low measured O2 error again. I am unsure on what else to look for that could be causing the error coming up? Any help is appreciated.

I have a Hamilton T-1 service manual. I tried to email it to info@... and received a reply that it is too large. The other way to send it states that they have reached the quota limit. Please let me know how I can share the manual. Thank you
