Title: PT100 Post by: Tom1234 on August 13, 2017, 11:57:28 23:57 I would like to use a PT100 sensor from farnell ( http://uk.farnell.com/w/c/sensors-transducers/sensors/temperature-sensors/prl/results?st=pt100&sort=P_PRICE )
firstly i don't know what sensor to choose (class A or class B) and also what circuit to build for this sensor. Anyone can help me on this issue?

But let me help you firstly i don't know what sensor to choose (class A or class B) and also what circuit to build for this sensor. Anyone can help me on this issue? https://www.google.com/search?q=temperature+handbook+pdf I can recommend the LABFACILITY TEMPERATURE HANDBOOK and the Maxim handbook but much of the hits on the first page are good material. After that knock your self out with a search like this https://www.google.com/search?q=pt100+circuit+design Title: Re: PT100 Post by: javad_amini on August 26, 2017, 12:18:49 00:18 You need to define requirements of your project first. acceptable cost and accuracy, etc. Then you can make a good choice. There are many chips that can be used to utilized PT100. If I remember correctly MAX31865 can be a good choice. As I stated before, you need to define the project requirements first.
Good Luck Title: Re: PT100 Post by: Tom1234 on August 26, 2017, 07:46:11 19:46 I was thinking about a range -20 to 200 C.
I would check the ic MAX31865 |
