Gas Sensor Testing System

Designed and developed with the help of IMQ – ISTITUTO ITALIANO DEL MARCHIO DI QUALITA’.

Features:

• Three independent test cells , each with its own sensors to monitor constantly pressure, temperature, relative humidity and flow speed.
• Thermal regulated chamber allows an accurate setting of temperature.
• Microprocessor program is used to control every valve and to calculate gas flows and gas mixtures at desired concentration, humidity and temperature.
• Total control of dry and wet flows permits to obtain specified relative humidity value.
• Mass spectrometer to monitor actual gas concentrations.

Climatic Chamber With Three Testing Cells:

• Air sealed ( vacuum-tested ) cells ensure gas sensor heads an interference-free space.
• 3-pin connectors bring power supply and 12-pin connectors carry various other signals to every cell, so almost every gas tester can be easily mounted and interfaced with the control system.
  

Automatic Gas Flow Control:

The system provides:
• 3 mass flow controllers : 2 air ( to give dry and wet air ) and 1 gas , with a valve system to distribute gas mixture flow.
• a thermoregulated humidifier , to provide 100% wet mixture.
• a thermoregulated condenser to eliminate extra humidity.
• This allows maximum flexibility on preparing gas flows at a given concentration , humidity and temperature.

With these parameters , the control program provides complete automatic sequences to verify all test in conformity with CEI norms. Computer Controlled Mass Spectrometer: Complete feedback on gas concentration is obtained by a computer-controlled mass spectrometer. Software PPT430 allows constant monitoring of cell contents, showing actual system concentration of gas. It is also possible to log data on disk , filling in reports on system activity. A special Close Source allows good readings even at low concentrations ( a few PPM) of gas mixture ( like CO, CH4 , C4H10 , and so on ).
