Temperature sensors – like all other sensors – must be calibrated at regular intervals. This ensures that they deliver accurate and consistent measured values. Temperature calibration (e.g. using a calibration bath or dry-well calibrator) is generally carried out …
Not all calibrations are the same. This is illustrated by the example of “Thermometer calibration” - which test method is used depends on various factors such as process conditions, quality standards and safety requirements. Depending on the method, the calibration …
When a constant current is passed through a thermometer of resistance Rt and a fixed reference resistor of known value Rs, the voltage across them will be in direct proportion to their resistance values. The ratio of the two voltages and therefore of the two …
