3.1 alternating pressure test cyclicpressuretest the instrument is applied to a certain extent, frequency, according to certain rules reciprocally alternating load.

4 Overview

The main instrument for pressure test instrument can also be used for precision measurement of pressure and vacuum.

The instrument works by using elastic sensing element (such as a spring tube) elastically deformed under pressure, which Role of pressure and deformation of a certain linear relationship, through a transmission mechanism amplified by the pointer indexing disc Indicative of the measured pressure. Flexible sensor instrument commonly used spring tube, but it may take other forms Elastic sensing element.
