Temperature Measurement and Sensor Immersion Depth • Temperature measurement requires a temperature sensor or transducer. • Small blocks are more affected by loading errors than larger volumes. • The depth of sensor immersion affects measurement accuracy. • Dry Blocks have good uniformity, typically over the bottom 40mm of the pocket. • Best practice is to place a calibrated probe in the block and compare thermometers to the reference probe. • Calibration in Dry Blocks depends on the application, number and types of sensors, temperature range, and required accuracy.
