Thermowell for PT100 Sensor

[Mungri]

Hi everyone
Just finished building a PID controller with a single socket to control my Peco boiler.
Used this PT100 sensor.
https://www.aliexpress.com/item/2-m...165.html?spm=a2g0s.9042311.0.0.5d014c4dYn3gyy
All set up and auto tuned now. Seems to be working really well.
I could just hang the sensor over the top of thePeco as I did for the auto tune, but if possible I'd like to fit a thermowell to the Peco.
Problem is I haven't a clue which one will suit the PT100 I bought from Ali Express.
Anyone got any idea?
Cheers,
Ian.

Hi!
I went for this type of sensor - a couple of washers, seals and a nut and it fits snugly in my HLT.
There's a similar one on ebay.

I use the same ones as Col. Would advise the same to attach it directly into the boiler and skip the thermowell.

Thanks @Bigcol49 , @BeerCat .
Do you keep everything together as one unit all the time then? ie you don’t disconnect the sensor from the controller or the hlt, which would be a pain in my case.
Hope that makes sense.

The sensor has a plug on it for easy removal.

Hi!
I prefer to disconnect both plugs and store the lead separately.

Apologies. Should have read the blurb. A plug and socket version makes a lot more sense.
