- If a temperature controller has a set-point of 121°C, and the control sensor is a platinum resistance thermometer, whose resistance is increasing with time due to ageing; does the process temperature increase, stay at 121°C or decrease as the PRT ages?
- If a temperature controller has a set-point of -20°C, and the control sensor is a platinum resistance thermometer, whose resistance is increasing with time due to ageing; does the process temperature increase, stay at -20°C or decrease as the PRT ages?
