The dead weight tester is primarily used to calibrate which equipment?

The dead weight tester is primarily used to calibrate pressure gauges. This device operates by applying a known weight to a piston, which generates a precise pressure value. By correlating this pressure with the output reading of a pressure gauge, technicians can determine the accuracy of the gauge and make necessary adjustments as needed.

Pressure gauges measure the pressure of fluids and gases in various systems, and their accuracy is crucial for ensuring safe and efficient operation. The dead weight tester provides a reliable and standardized method for checking these instruments against a known reference, which is essential in maintenance and safety protocols. This tool is particularly valuable in settings where precise pressure readings are critical, such as in hydraulic systems or during testing of pressure-related equipment.

While meters, pneumatic probes, and liquid level gauges may require calibration and testing, they typically utilize different methods and tools tailored to their specific functions, making the dead weight tester specialized for pressure gauges.
