RTDs or Resistance Temperature Detectors are widely used to measure temperatures in all kinds of industrial products. In many cases PT100 or PT1000 is specified. PT100 stands for 100 Ohm Platinum RTD, PT1000 stands for 1000 Ohm Platinum RTD.

Platinum, a precious metal, has seen dramatic price increases over the last 10 years. In 1999 platinum was about $400 per ounce, today it is $1700 per ounce and it peaked at $2200 per ounce in 2007.  This has caused platinum RTDs to increase in price dramatically.

In the above example, our customer came to us to redesign their current part to make it more cost effective. We were able to shrink the part and integrate a threaded screw reducing part count and making it easier to install. A strain relief is built in for the flying lead which makes the overall package very robust.

We also transitioned from a platinum sensing element which has a TCR of 3850ppm/C to a low-cost, iron based wire which has a TCR of 3500ppm/C.
