If you change the 5k ohms sensor in a temperature controller to a 10k ohms sensor with a similar temperature range, it will likely have an impact on the controller's temperature reading and control behavior. The specific effects will depend on the design and calibration of the temperature controller, but here are a few possibilities:
Temperature Reading Offset: The temperature controller may display a different temperature reading compared to the original sensor. Since the resistance-temperature relationship is different between the 5k and 10k sensors, the controller's calibration might not match the new sensor's characteristics. This could lead to an offset in the displayed temperature value.
Control Accuracy: The temperature controller uses the sensor's readings to determine when to activate or deactivate a heating or cooling system. If the 10k ohms sensor has a different response time or sensitivity compared to the original 5k ohms sensor, it may affect the controller's ability to accurately control the temperature. The controller might turn on or off the heating/cooling system at different points, resulting in less precise temperature control.
Calibration Adjustment: Depending on the temperature controller's design, it might offer calibration options or adjustments. If available, you may be able to recalibrate the controller to match the new 10k ohms sensor. This calibration process typically involves adjusting the controller's settings to ensure it accurately corresponds to the temperature measurements from the new sensor.
It is important to consult the temperature controller's documentation or contact the manufacturer to understand the compatibility and recommended procedures for changing the sensor. They can provide specific guidance on how to handle the sensor replacement and any necessary adjustments to ensure accurate temperature control.
