DEVICE FOR MEASURING OF LOW CONCENTRATION OF HYDROGEN SULFIDE
Purpose of the development:
Purpose:
--- Check leakage of hydrogen sulphide in the air at room temperature and atmospheric pressure;
--- Measuring the concentration of hydrogen sulfide at room temperature in air or gas mixtures
inert gases (1) at atmospheric pressure, (2) under reduced pressure (10 - 380 mm Hg).
Recommended application field:
Ecological monitoring of the environment.
Technical characteristic:
Specifications:
- Range of hydrogen sulfide in the air,% vol. 0-10 [-4];
- Sensitivity,% vol. 5.1 x 10 [-6];
- Temperature sensor, * C 20 + / - 10;
- The length of the link, m 1;
- Cooling air sensor;
- Continuous mode;
- Overall dimensions: 80 x 40 x 45;
- Power supply voltage Vcc, B 9;
- The maximum supply current I, mA 100;
- Cable length of the measuring unit to
registrar, m, 300;
- Weight sensors, not more than 0.1;
- The block measuring 0.6.
Advantages over analogues:
Has significant advantages over similar products. In particular, before the gas sensors "Figaro" (Japan)
have unstable working conditions and relatively high price. German electrochemical sensor
GDA IMS has a short life and large size.
The patent of Ukraine № 25784 from 27.08.2007, the utility model "method of manufacturing
semiconductor gas sensor which is sensitive to hydrogen sulfide. "
The development stage readiness:
Ready for application
Description of the development:
()
The principle of the gas analyzer is to measure the capacitance of metal-insulator-semiconductor
which depends on the volume of hydrogen sulfide in the gas mixture. Gas analyzer consists of a remote probe with
sensor and measuring unit.
Measuring unit processes signals sensor monitors its performance reflects the existence of
hydrogen sulfide in the atmosphere on the LED display and transmits data to devices that record the signal or
personal computer in the form of an analog voltage signal.
