RTD SENSOR - OHMS vs. TEMPERATURE
The following chart shows what the ohm reading would be for a given temperature. The
following are the instructions for use.
1.
Measure the resistance (Ohms) of the sensor in question with an Ohm meter.
2. Find the reading in the chart.
3. Follow the row to the left and get the temperature in 10° increment, then follow
the column up to get the 1° increment. Example: 1573 Ohms =302°
