Introduction

JJF 1002-2010 "national verification procedures write rules", JJF 1001 "common measurement terms and definitions" And JJF 1059 "Evaluation and Expression of Uncertainty in Measurement" together constitute the basic outline of this series specifications developed. This outline cited JJG926 "recording pressure gauges, pressure vacuum gauge and vacuum gauge" all the provisions of the other Also referred to the GB/T 1226-2010 "General gauges" and JJG74-2005 "industrial process measurement recorder" Part of the provisions, the test conditions specified in other test items and test methods, it is possible to record pressure gauge, Performance pressure vacuum gauge and vacuum gauge to make objective, comprehensive and effective evaluation. The outline of the structure in accordance with JJF 1016-2014 "appliance type evaluation outline guidelines for the preparation of measurement" orchestrated Each chapter in accordance with JJF 1015-2014 "measuring equipment type and universal norms" and JJF 1002-2010 "Country Write rules prescribed verification procedures "be prepared. This outline is the first release. Recording pressure gauges, pressure vacuum gauge and Vacuum gauge type evaluation outline

3 Overview

Instruments for measuring and continuously recording the magnitude of the measured pressure or vacuum. Instrument works as follows. the elastic element at a pressure-sensitive type or sparsely empty action, elastically deformed by machine Mechanical transmission amplification mechanism, driven stylus pressure tested empty or sparsely magnitude recorded in the removable recording paper. Instrumentation includes detection means, transmission amplification mechanism, the recording sheet moving mechanism, automatic recording and display apparatus four most. Recording paper pressure units of measurement, move the clockwork mechanism There are two kinds of motors and special synchronized. The instrument can be divided into single or multiple recorders gauge, disc-shaped, bar or table type recording paper to gauge And one or more discrete areas gauge records three types. Key components of the instrument are mainly spring tube, the movement and the recording sheet moving mechanism and other key parts and materials Table 1.
