extending rtd wires?
 
I have the deluxe rtd probes from auber. The leads they provided coming from the xlr aren't long enough to reach my pids. What is the best way to go about extending them? Can I simply use butt crimp connectors with heat shrink tubing or does wire this small need to be soldered? I have soldered copper, but never anything electrical and would like to avoid it if at all possible. Thanks in advance...wnc

That's my one complaint about those probes and what's keeping me from ordering them right now. 12" from the connector to the spade connectors on the leads just doesn't seem long enough. Wish they had an option for a longer set of leads.

As for extending, you could butt splice them, but I'd probably run them to a terminal strip and then run another wire from there to your PID controller.

Use something like this:

I am contemplating emailing them and seeing if they would extend the 12" piece to 24". 12" seems too small to me too.

No problem at all extending a RTD probe's wiring.

It is a whole 'nother' ball game if the probe is a type 'K'.

Call them. I'm sure that the owner would be more than willing to help you.

Make sure that all the wires are the same lenght though.

Gosh, don't know why I didn't think of that...I have tons of empty space left on the terminal strips I used to wire up power and pumps...thanks everyone

Ps-this is my only complaint with the probes. Other wise I think it was well worth the extra nine bucks for the deluxe upgrade

I emailed them with a question once and they responded in less than 2 hours. I have to assume they value customer service highly. I will report back when I get a reply.:mug:

Optional Deluxe Cable. The standard cable supplied with sensor is shown in the above picture. It is 6 ft (2 meters) long, color-coded three-conductor cable with two layers of TEFLON insulation that is very strong and weather resistant. Based on the customer's feedback and request, now we are also offering the deluxe cable for the probe: an 8 ft long TEFLON insulated cable with stainless steal braid for more protection. This cable also comes with a pair of panel mount connector on the other end. The mating connector of the panel mount connector has 1 ft of TEFLON cable installed. User can use this cable without any soldering work.
Liquid Tight RTD Sensor, 2 Probe, Weldless Fitting

Seems like the description of the product says a lot.

I have probes I already bought but they are not the deluxe cables and I wired them too far away from my pids where 12" won't reach. I can rewire them and drill new holes in my control box if I need to.
