ГАММА-100 – multifunctional gas analyzer of multi-component mixtures

Designed for measurement of one, two or three components: carbon oxide (CO), carbon dioxide (CO₂), methane (CH₄), nitrogen oxide (NO), sulfur dioxide (SO₂), oxygen (O₂), hydrogen (H₂), nitrogen (N₂), helium (He) in binary and multi-component mixtures.

Application: in automated process control systems in ferrous and non-ferrous metallurgy, cement and glass industries, at brick and ceramics manufacturing plants, in chemical and petrochemical industries, at combined heat and power plants and state district power stations, boiler plants, etc.

Principle of operation:
СО, СН₄, NO, SO₂ – optical-acoustic;
СО₂ – optical-acoustic and thermoconductometric;
Н₂, N₂, Не – thermoconductometric;
О₂ – thermomagnetic and thermoconductometric.

Sampling - forced (flow rate pump is not a component of the device).
Version – general purpose industrial, for installation in non-explosive areas.

Functional capabilities
01. Digital indication of measured component concentration on each measuring channel;
02. Generation of unified output current signal proportional to analyte concentration;
03. Generation of text and light alarm indicating that analyte concentration exceeds or drops below threshold values;
04. Commutation of external circuits with two groups of switching relay contacts (“dry contacts”) for automatic actuating device switching-on (-off) upon alarm actuation indicating that the measured component has reached the set threshold values (excess or drop);
05. Output if data on measured component concentration in a digital form via RS 232, RS 485 and Ethernet (depending on version).
06. In addition to the option of concentration reading on main channels, gas analyzer also has an option of control via RS 232 (RS 485) communication channel, i.e.:
- adjustment of scale initial value;
- adjustment of scale finite value;
- thresholds setting.
