Service is great as always. However, probe came with nut so don’t need it. Picture of probe does not show nut which is why I ordered it.

Part number 11-04603 DAVTRON TEMPERATURE PROBE 12FT. WHITE (ANALOG) is the correct probe required for the Aerovonics AV-20 instrument. Part arrived fast from Spruce East in factory packaging.

Reading from this probe matched reading from another system within one degree. It was not clear that probe D307PS included a probe nut

Q: is the c307ps probe a a j or k type tc.?

Per Davtron, this an analog AD590 it is current drawing not resistive.

Q: Does this probe (part # 11-04603) measure C or F?

Yes , This probe measures temperature range from -55 c to +125 c (-67 F to +257 F) .

Q: On the c307ps white wire is Positive white/blue Neg. but Garmin GTX330 pin outs say Probe IN and Probe OUT. is the white (POS) wire IN or OUT?

The positive wire would have to go in the IN position.

Q: Can the C307PS be shortened in length to approx 2.5 to 3 ft? Would this affect performance?

Per the manufacturer, you are able to shorten the length without affecting calibration.

Q: Is the 7/16 nut and the washer that holds the O ring included with the C307PS probe (part number 11-04603)? Or must they be purchased separately?

Yes those are included.

Q: Hi , can you confirm if p/n 11-04603 DAVTRON TEMPERATURE PROBE 12FT. WHITE (ANALOG) and 10-07292 MCI CHRONOS DIGITAL CLOCK 6420093-5 work together ?

Per manufacturer,"The ch93 supports two different types of temperature probes; rtd and current sense devices". Being that this probe is current sensing, it should be compatible.
