Air Temperature Sensor

[pacecapt]

I am considering adding a generic Air Temp sensor inside the engine compartment on my Experimental Aircraft. I have a two wire sensor (like you would use on a Grill) that I would like to connect to my Dynon HDX system. Any recommendations on which leads to connect it? There is currently no other air temp sensors that I could get the data from.

I don't know if the grill sensor would work, but the below if from the manual.
It can't hurt to hook it up to the general purpose temp sensor pins and try different configurations.

K-Type Carb Air Temp Thermocouple

Hi all I'm installing a Skyview HDX system in my aircraft which will replace an Electronics International (EI) G1 Graphic Engine Monitor. My existing Carb Air Temp sensor is an EI supplied 610C-021 K-Type and I've connected this to EMS D37-23. However, I'm not sure how to map this...

If it's a thermocouple, it should work. Thermistor might as well. Either way, you'll have to experiment to get the readings you want.

Note that thermocouples generate a very small voltage (mVolts) and thermistors are a variable resistance, so these two need very different circuits.

It is a thermistor style which is the same at the Dynon OAT…
