How do I know if I need a 100 ohm part or a 1000 ohm part?
-
I have worked with both Balco and platinum sensors in various applications. I like that a high resistance Balco sensor costs less than a platinum one, but I find that the resistance of the Balco sensors seems to shift more over time. Is Balco more sensitive to environmetal factors such as humidity and pressure? What else could be ...

Why does Kapton have a bad reputation in the aerospace industry? I have an end user who is uncertain about using Kapton heaters and sensors. Are his concerns justified?

Question 1 - Yes this can be done. The only error you will get from the leadwire itself is if the resistance of the leads are mis-matched. This can be avoided by using all one color wire that comes from the same spool. Also, using a 1000 ohm part versus a 100 ohm part helps to keep the overall leadwire resistance a lower ...

Yes, an RTD is still an option at this temperature. Standard temperature tables for RTDs cover from -260°C to 962°C. The trick is finding an insulation for the sensor that is good up to 400°C. Perhaps you could use an integrated thin film element or ceramic element.

The same features that drive up the cost of a single element Thermal-Ribbon, exponentially increase the cost of a dual element part. Since materials are relatively insignificant in a Thermal-Ribbon (parts are usually small), there is not a lot of material cost savings for a dual element. Tight resistance and dimensional tolerances ...

First of all, there are actually several different lead-free initiatives out there. The most prominent one is the ROHS (Restriction of hazardous substances) directive passed by the European Union. Japan and some other countries are passing their own laws. So your answer depends on where you are selling product. For the most ...
