Shock tube‐based calibration installation for dynamic pressure transducers and performance testing

Dynamic Calibration Methods for Force Transducers

Three Methods for evaluating the dynamic response of force transducers against varying force are described in this paper. In all methods, the inertial force of a mass is used as the known dynamic force, and this reference force is applied to a force transducer under test. The inertial force is measured highly accurately as the product of the mass and the acceleration. An aerostatic linear beari...

On the Calibration of Pressure Transducers for use in Shock-Tunnels

Transducers and Transducer Calibration

ed from: Figliola, R.S. and Beasley, D. S., 1991, “Theory and Design for Mechanical Measurements” GENERAL MEASUREMENT SYSTEM Assigning a specific value to a physical variable is done with the help of a measurement system. Once a value has been assigned to a physical variable it becomes known as a measured value. There are four stages to the process of assigning a value to a physical variable. G...

Towards a shock tube method for the dynamic calibration of pressure sensors.

In theory, shock tubes provide a pressure change with a very fast rise time and calculable amplitude. This pressure step could provide the basis for the calibration of pressure transducers used in highly dynamic applications. However, conventional metal shock tubes can be expensive, unwieldy and difficult to modify. We describe the development of a 1.4 MPa (maximum pressure) shock tube made fro...
