The Piston Dead Weight Tester is an essential tool for calibrating pressure measurements. It functions as a standard calibration device, using a piston cylinder mechanism to apply a load and establish equilibrium with the pressure below the piston. These testers are considered primary standards, meaning that pressure readings derived from them are based on fundamental quantities such as length, mass, and time.
Most often found in calibration laboratories, dead weight testers play a crucial role in calibrating pressure transfer standards, including electronic pressure measuring devices. By providing a reference pressure traceable to fundamental physical quantities, dead weight testers ensure the accuracy and reliability of pressure measurements across a wide range of applications.
