Note 1: The PT100 sensor uses an integral sintered outer-wound ceramic platinum resistor. If other PT100 components are selected, the accuracy and stability depend on the stability and repeatability of the component.
Note 2: The sensor model and temperature range listed in the table are the most commonly used, the most stable, and the most representative sensor and temperature range. If you want to confirm other models and temperature ranges and accuracy, please contact with the manufacturer.
