This two-channel card is specially designed for temperature measurements with the platinum resistors PT100 and PT1000. It is installed in the DAS30 and DAS50 data loggers at the factory upon request. This results in the possibility of a 2-, 3- or 4-wire measurement per channel, whereby the resistance values are recorded via a 20-bit A / D converter. Overall, excellent and accurate measurements with the corresponding resolution can be achieved.
