This Tibbo BASIC demo application supports PT100, PT200, PT500, and PT1000 sensors (this is selectable in code, see the main.tbs file).

Tibbit #22 is very accurate. Here are the results of measurement comparisons between the Tibbit #22 and a Fluke 726 process calibrator:

You will need:

Connecting the RTD sensor

You can use 2-wire or 4-wire sensor connection. The 2-wire connection does not allow the system to compensate for errors caused by cable resistance. Therefore, this type of connection is suitable for cases where the sensor cable is short.

The 4-wire connection eliminates errors caused by cable resistance. It is recommended for cases where the sensor is located at some distance from the Tibbit.
