Description:
The gas analyzer is designed for automatic, continuous measurement of the concentration of explosive hydrocarbon gases or carbon dioxide in the surrounding atmosphere. Explosive gases are calibrated using methane, propane or hexane. Designed for stationary installation.
Overview:

Application area

Explosive areas of rooms and near outdoor process plants in which explosive mixtures of gases and vapors with air may form, according to GOST R IEC 60079-14-2008 and explosion protection marking 1Exd [ib] IIC T4 Gb X.

Features

It consists of a transmitter and a gas optical converter (PGO).
PGO performs all metrological operations to determine the concentration of the test gas, including the formation of a digital signal and an analog output signal of the current loop containing information about the measured concentration. PGOs have built-in flash memory with calibration coefficients, which are automatically read when connected to the transmitter by a microprocessor, which eliminates the need for individual calibration (calibration) of transducers with a transmitter.

The transmitter provides information on the measured concentration via the digital serial interface RS-485 MODBUS®, as well as the concentration of the analyzed gas on the built-in four-character seven-segment display and light indication (using indicator LEDs) of the supply voltage, the measurement range is exceeded and the self-diagnosis results are also switching built-in relays.

The gas analyzer is also equipped with a HART-communicator connector for controlling the device.

Key Specifications
