Detachable pt100 temperature probe
Detachable pt100 temperature probe
Just received this detachable temperature probe from eBay, shipped from China. It was less than a £10 delivered. I've tested it with my pid and it seems to work perfectly. It will be handy when cleaning out pots etc :)
Thought I'd share it for anyone interested.
Listing number on eBay 381466785508

Good find!
I have ordered one to replace my fixed PT100 probe in my boiler.
Best regards,

Re: Detachable pt100 temperature probe
Ive been looking for these for ages , saw them on a post and then couldnt find it . Thanks
Edit: Bum, these are pt100 , no sign of ntc ones

Re: Detachable pt100 temperature probe
did i miss the all important link??
after snagging the probe leads a few times during clean up and put away, so was planning to switch to thermowells ..

Re: Detachable pt100 temperature probe
I've given up with "connectors" I've tried a few types and they worked at first but a few batches later and they failed.
Ugly but functional I currently using plain screw blocks

They always give repeatable connection!

Re: Detachable pt100 temperature probe
Gordito, wondering how you're getting on with this probe? I've purchased a similar one which should hopefully arrive by Saturday (UK-based seller, but same item). Is the seal ok? (assuming you've used a BSP nut as I intend on). Thanks.
Re: Detachable pt100 temperature probe
I bought a few of these.
The 1/2" thread is watertight with a few turns of PTFE.
I did find variations in the ohm value at 0 degrees.
One reads 96.7 ohms and the other reads 98.
Been testing them out on an Arduino Uno and an LM358 circuit with 31.57 gain.

Re: Detachable pt100 temperature probe
Cheers brewzone, was a bit difficult finding an answer whether NPT and BPS threads were interchangable (or more accuratelt whether it would provide a decent seal) seemed that 1/2" fittings were but good to get some confirmation.
Re: Detachable pt100 temperature probe
Ohm value shouldn't be an issue on say a sestos or Rex c100 when calibrated for zero C.

Re: Detachable pt100 temperature probe
Arrived today after ordering Wednesday, paid a bit more from one of the UK based obviously Chinese shops. I have an Inkbird 100, will let you know how it fares.
Re: Detachable pt100 temperature probe
I have been using one of these for a few months and its excellent. I tested it against 2 thermometers and a 10" SS probe on an STC1000 and its spot on. Have not had to calibrate it.
Re: Detachable pt100 temperature probe
I may have to order some of those. It the moment I changed the connector at the end to xlr connectors so I can jyst plug them into the wall outlets, but detaching at source looks a much better solution

Re: Detachable pt100 temperature probe
Been a few months now since I posted to this discussion.
Bought a couple of these PT100 probes and set out to build a dual PID system around an Arduino Mega and RPI3.
Initially I used a diy opamp circuit to connect the PT100's to a UNO but found there was not enough resolution.
Have since bought some MAX31865 amplifier boards which are great.
After a few trial runs on a 33L test system overshoot is down to 0.67C
Running in a simulation this is down to 0.04C
Just got to sort the lag out to achieve the 0.04C on the 33L system and then incorporate this into a RIMS and Herms system.
