Your questioning about the accuracy is worth of the concern. Hallo Alan, beside the newer digital sensors, as Michael has suggested in his reply, in applications like your's KTY11-5 is often used. Datasheet you will find here: http://www.datasheetcatalog.com/datasheet...11-5.shtml A circuit to handle its signal could be the following:  As you can see from above formula, this sensor supports concept of 'ratiometric conversion', means sensor output signal linearily depends on 'Uaref'. Make the reference voltage of ADC equal to 'Uaref' and in first order approximation changes of 'Uaref' have no effect on sensor reading! Kai |
