How would you calibrate a sensor system using...?
...a thermistor in a drinks machine, so that p.d changes across the thermistor and the machine can act accordingly. ROughly how would that be calibrated? Thanks
Likely a drink machine delivers either very hot or very cold beverages. The thermistor can be subjected to ice in water (32F) or boiling water (212F) to correspond to the setting(s) of the machines temperature controller. Then set the controller to the desired temperature and check (approximately) a sample drink with a good (scientific) thermometer in the correct range for the setting. Of course let the machine stabilize first. For practical purposes, merely use the thermometer to test the product.
