Difference between accuracy and precision

Accuracy “Accuracy gauges how closely results match the real or predetermined value” Precision “Precision assesses how closely related outcomes are to one another” Comparison Chart between Accuracy & precision Basis for Comparison Accuracy Precision Meaning Accuracy refers to the degree of agreement between the absolute measurement and the actual measurement. Precision refers to the degree of variance present in the results of multiple measurements of the same factor. Represents How Closely result agree …

What is Dry Block Calibrator and how to use it?

Calibration

What is a Dry Block Calibrator? A dry block calibrator in other words is known as a dry well calibrator. These dry block calibrators are used to calibrate various temperature sensors such as Thermocouples, Thermometers, Thermistors, and RTDs in a liquid-free enclosure. Dry blocks are used when the sensors need to be tested for both …

What are various Level calibrators and How to use it?

Calibration

What is the purpose of a level transmitter? The purpose of Level transmitters in the process industry or in power plants produces continuous level measurements over the system range other than at a single point and produces an output signal proportional to the level in the vessel. The generated output signal is used to display …
