alexmoskos Posted February 23, 2017 Report Share Posted February 23, 2017 Hi, I already have a couple of PT1000 temperature sensors that I would like to use with the expansion module UIS-WCB1 but the specification says it can only work with PT100 (and other thermocouples) but not PT1000. The temperature range this sensor will ever see is between 0-100 C. Because of this relatively smaller temperature range, would I be able to use the PT1000 sensor with this I/O module, by writing some code to account for the difference, instead of having to purchase the UIS-04PTKN module?

MVP 2021 Joe Tauser Posted February 24, 2017 MVP 2021 Report Share Posted February 24, 2017 Look at these resistance tables- 100 ohm RTD http://www.pyromation.com/Downloads/Data/385_c.pdf You'll note the highest reading is 390 ohms at 850 C 1000 ohm RTD http://www.thermometricscorp.com/PDFs/Platinum-1000-Ohm-385.pdf All the values are increased by a factor of 10. A 100 ohm input will totally barf if you connect a 1000 ohm load to it. Joe T. 2 Quote Link to comment Share on other sites More sharing options...
