How To Test PT100 Temperature Sensor : What is PT-100, Why We Need 3 Wires And How To Measure IT

[@remramyoucef9913]

thank you for explaining the principle in easy way

[@johnnygilbert57]

Thank you for posting this information, much appreciated

[@brianfernando9418]

Thanks for a such nice video could pause a video to test echo sounder transducer

[@mhikailibrahim934]

Can i perform the test while the RTD is in operation

[@MrPontibus]

thank you!

[@eng1897]

thank you so much ,,
excuse me I have a question do RTD need special wire?? or just wire ordinary??

[@btoash]

Hi my friend,
Actually no, you can use any electrical wire you want.
No problem at all

[@Hari8adi]

How long or how many years can a pt100 work efficiently. What could be approx expiry or validuty?

[@btoash]

Hi, its very depend, when installed correctly, avoiding mechanical and environment damage, lifetime of a pt100 can be up to 20 years.
I have pt100 sensors in my factory that are still working after 15-20 years.

[@cederbergfitness9797]

why not just say that the double wire on 1 end the 1 of the double wires acts as a base reference for the wire resistance

[@chrismorphet5466]

He shouldn't be measuring the resistance by holding both in his fingers. Bad practice as you can pick up resistance from your body!

[@btoash]

Thank for the comment my friend.
But actually i am working with rtds for 10 years now, and never had a problem measuring resistance with my hands.
