PRESSURE-PULSE GENERATOR FOR THE CALIBRATION OF PRESSURE GAGES
NAVAL ORDNANCE LAB WHITE OAK MD
Pagination or Media Count:
A pressure gage calibration device is described which is especially useful for piezoelectric type gages having short RC decay time. The device produces a positive going, isothermal pressure which is in the form of a step pulse with a rise time of less than 100 micro seconds. Calibration pressures from 0.1 psi to 1,000 psi are obtainable using any gas as a working medium. Provision is made for simulat ing ambient pressures from high vacuum to several hundred psi during calibration.
