Hi all,
Is there any chance to read thermistors more than 10K ?
In particular I have to use 12 22K ohm thermistors.
Thank you in advance,

Hi Pets,
Unfortunately the maximum resistance the NI 9219 can measure is 10.5 KΩ. Other posts are related to the same issue. If you need to measure temperatures below 0°C you will still need external signal conditioning (such as a shunt resistor in parallel with the thermistor): see: thermistor data acquisition using cDAQ-9172 You can even measure the thermistor with a 9215 but using this module would require external excitation current and signal conditioning too.
