Fixed gas analyzer ГТВ-1101ВЗ-А is designed for measurement of hydrogen volume fraction in process gas mixtures (nitrogen and air).
Application: monitoring of technological processes at nuclear power plants.
Principle of operation – thermoconductometric.
Sampling – diffusion and forced.
Operation – continuous.
Version – atomic.
Gas analyzer consists of:
- measuring transducer MT;
- remote primary measuring transducer PMT (from one to four for one MT).
Ingress protection rating:
- MT –IP20;
- PMT – IP65.
Explosion protection marking:
- MT – general purpose industrial, for installation in non-hazardous areas;
- PMT – 1ExdIICT6, for installation in hazardous areas.
- digital indication of the measured component content;
- light and audible indication when alarms «Threshold 1» and «Threshold 2» are reached;
- commutation of external circuits with one group of switching relay contacts when alarms «Threshold 1» and «Threshold 2» are actuated;
- generation of information on concentration of the measured components by current output 0-5 or 4-20 mA (on demand) on each measuring channel.
