Insulation Material/Waterproofing

Post by MoMoney$$$;)0) » January 2nd, 2020, 4:42 pm

Hello. So I was wondering if any type of Insulation Material is even required since my probe works fine with soldered wires and heat wrap (and the wire is already insulated as/is so is there any type of requirement to have some sort of coating on the length of your whole probe, or is that not necessary. (Considering it's no needed). Also how would you exactly explain this since it's not like you put some type of special material on it to be thermally conductive, and electrically insulative. Thanks.

insulation of any kind isn't required in the rules, so you should be fine. Per the rules, you are allowed to have an insulated probe as long as the insulation wasn't applied by the manufacturer; buying pre-insulated sensors isn't allowed.

I agree that it shouldn't be necessary to thermally insulate your probe everywhere, but like you already did, you will need to electrically isolate your individual joints so they don't touch.

Too much insulation is not good anyway, since it reduces response time. Since the max temp is only 75 C, if your wires are insulated enough as they are then its good!

I have a similar question, would it work if I were to cover my thermistor in either a plastic bag, sorta like a medical thermometer cover, or if covered it in hot glue or spray-foam?
Thanks!

They will all work, here is the but:
they may take quite long to get stable reading or reach thermo balance. Easy to test, so just try it out.

We just cover and seal the wire part and let the sensor head exposed to the water, plastic dip or liquid electric tape is better than hot glue.

Another way, you can buy some thermo glue which passes heat but not electricity.

I would just go with liquid electrical tape, it is relatively cheap, lightweight, waterproof, and electrically insulating.

Epoxy is the way to go. Do your research and you'll find what you need.

hi. to build our own “thermometer” we can place our sensor (TI LM19) into a straw and use hot glue to keep the TI LM19 in place right?

Hi! Just a gentle reminder that you don't have to post the same thing in multiple places. To answer your question, since the LM-19 is an allowed sensor, I don't see why not.
