Parts Locations in DigiKey[edit]
Notes:[edit]
Need qty sets=3 as a minimum so order 4 or 5 sets
Thermistor Measurements[edit]
- 0 C == 101 ohms ratio = 0.92
- room == 110 ohms ratio = 1 ( room = ~ 70 degrees )
- 100 C == 135 ohms ratio = 1.22
Ratios turn out to be exactly like Platinum RTD. See Part datasheet
- Ordered Digikey part number = PTS1206100CT-ND DataSheet PTS1206100CT-ND TEMP SENSOR RTD 100 OHM 1206
- Digikey PTS1206100CT-ND
Observations[edit]
- EPROM board appears to be identical between TEMPERATURE & PROCESS > HIGH CERTAINTY
- Interconnect board is identical in rev and in packing >HIGH CERTAINTY
- Display board is identical > HIGH CERTAINTLY
- Power supply board appears identical > Medium Certainty
Conclusions[edit]
- Signal board appears to be the source of the difference.
