The Ametek DLC Series Temperature Sensor gives significant improvement in the calibration accuracy. Axial homogeneity in the calibration well is important, as the typical thermo-sensitive element of a sensor can vary from 5mm to 60mm. The actual temperature in the well will inherently deviate from the ideal temperature as a function of the proximity to the bottom of the well.

The DLC function in the RTC calibrators provides automatic documentation by indicating when the temperature has stabilized and can be read with optimal precision. The best calibration result is obtained by using the Green-Zero rule as shown on the picture.
