Where can I find affordable RTD temperature probes with high precision?
Lately I've been looking into cheap RTD temperature probes for a little monitoring system I'm working on, and I didn't think it would be such a pain to research. I initially assumed most probes would give roughly comparable results, but after looking at specs and reviews I found that the precision ratings and construction quality could be quite different. I’ve looked at some listings online like Amazon, alibaba, and few other industrial sites to evaluate the pricing and configurations. Some of the ones I found actually had some fairly good options for the amount of money spent, In particular the probes with the calibration time ranges and temp tolerances included. What I'm trying to do now is achieve the most accuracy with a reasonable price that doesn't far far over the budget for just a basic project. Another thing I've observed is many people saying that you should look at probe material and response time other than the advertised fineness numbers. I'm interested to know what sources people here normally use for dependable RTD probes and if there is any type of brands or providers that work out well long term that don't get out of control financially.
