The depth of immersion of the sensor PRT, SPRT, Thermocouple
Temperature measurement requires a temperature sensor or transducer, such as a resistance thermometer, thermocouple, or liquid in glass thermometer. However, the temperature sensor may not be at the same temperature as the system being measured, and further introduction may change the temperature of the system. Small blocks are more affected by loading errors than larger volumes. we offers a range of insert sizes to suit all applications, including metal blocks with a temperature gradient.
The depth of immersion of the sensor is important, as it can affect the accuracy of the measurement.Dry Blocks are designed to have good uniformity, typically over the bottom 40mm of the pocket. Best practice is to place a calibrated probe in the block and compare the thermometers under test to the reference probe. When calibrating sensors in Dry Blocks, the choice of when to use the controller value or a reference probe must be made based on the application, number and types of sensor, temperature range, and required accuracy.
