3 Common Mistakes When Selecting an RTD Sensor
1. Choosing PT100 / PT1000 Without Checking the Controller: PT100 and PT1000 have different nominal resistance values. Better: Confirm the RTD element required by the control system.
2. Looking Only at the RTD Element Temperature Range: The complete probe may use cable, insulation and mounting materials with different temperature limits. Better: Evaluate the RTD Element + Probe + Cable + Mounting together.
3. Ignoring Probe Structure and Installation: A high-accuracy RTD element cannot perform correctly if the probe does not reach or contact the actual measurement point properly. Better: Confirm probe dimensions + mounting + sensing position before sample production.
