Calibration of Temperature Sensors in the Process Industry – Part II

To continue our discuss on calibration of temperature sensors in the process industry, we are going to move on to dry-block calibrators. Dry-block calibrators incorporate a heating/cooling element, but do not require the use of any liquids such as oil to perform their calibration tasks.  The units typically consist of a heating "block", an internal sensor, and some type of control to reach and maintain desired temperature ranges.  Some advanced dry-blocks also have internal reference sensors and associated accuracies thus eliminating the need for an external reference sensor.  Because there is no oil…Read more
