Oxygen meter multichannel Dozor-S-x-O2-655x

Oxygen meter multichannel Dozor-S-x-O2-655x

Scope:

Designed for continuous automatic measurement of the actual oxygen content of O2 in a gas mixture, including a mixture of smoke (exhaust) gases.

Benefits

The signaling devices consist of:

an electronic power supply and alarm system BPS, installed in a zone with a temperature of not more than 50 ° C; blocks of digital processing of signals PP, connected to the BPS using four-wire cables with the resistance of each wire is not more than 2 ohms. BPS can connect from 1 to 4 PP, installed in areas with a temperature of not more than 85 ° C; sensitive elements of the CHE installed in the O2 oxygen concentration control zones with a temperature of no more than 600 ° C and connected to the PP using special cables. On the basis of the measured O2 oxygen concentration values ​​in the flue gases, the indicators calculate the concentration of carbon dioxide CO2 and the excess air factor λ. The signaling devices provide the output of unified current signals (0-5) mA, (4-20) mA or (0-20) mA proportional to the concentration of O2, CO2 or λ (optionally) in each measurement channel, as well as the activation / deactivation of the executive devices signals when the programmed threshold values ​​of concentration of O2, CO2 or λ (optional) are reached. Alarms provide control of the operating temperature of the PP, as well as the temperature in the zones of installation of the CHE. The signaling devices are equipped with color, light and sound signaling to reach the established threshold values ​​of concentration O2, concentration of CO2 or λ, as well as a system for diagnosing communication lines connecting BPS and PP. The RS-485 interface provides remote access to signaling devices from a PC (operator console). Change of alarm settings is possible only after entering the password. Signaling devices are stationary measuring devices that operate in a continuous mode and do not require a sample preparation system.
