SFJ1103 Portable Gas Relay Automatic Tester

20111013203215406.jpg

Introduction

The instrument realizes automatic test  flow rate, volume, sealing and pressure release valve open, pressure close for gas relay. Test result could be automatically printed. The full automatic instrument takes advantage of advanced principle, uses microcomputer measurement and control. With digital display. The test personnel only need to labor in oil return. All measurement, parameter setting, control and print are automatically operated. There two models of  instrument: with and without release valve test.

The instrument uses independent gas source and microcomputer measurement. With computer monitoring and control box, sensors, solenoid valve, digital display, microprinter, mini electric air compressor and level gauge, the instrument gets electromechanical integration. On basis of the original products, a set of automated test  device for gas volume measurement is added to this instrument, error ≤5%. This allows to test for Volume scale plate of the gas replay.

The instrument cold conduct test of heavy gas flow rate, light gas volume and sealing performance. Test result could be automatically recorded and printed.
