Infrared gas analyser DID-МТ 1.000 – Ех
ASSIGNMENT - monitoring of pre-explosion ratio of hydrocarbon gases at vast interplaces of fabrication systems (up to 7500 m2), logging of diurnal, week-long and monthly emissions at a unified control house and in a relay room directly.
MODE OF FUNCTIONING – measuring of IR-absorption in hydrocarbon gases at two wavelengths on path of its dessimination from transmitter to angle reflector and back to receiver when scanning infrared emission ray in the chosen flat.
Measuring range of hydrocarbon gases concentration: 1 — 50 LET x m
(measuring range in LET×m for the 50 m length right-of-way meets 0.01 — 0.5 LET)
Measuring accuracy: ±5%
Temperature of ambient medium: from -40°С to +70°С
Gaging path length (doubled traverse of emission): 10 — 50 m
Number of gaging paths: to 20
«Ray move — measurement» cycle for single right-of-way, less than: 10 s
Device components: transmitting-receiving unit, telltale and computing device, a set of angle reflectors, guardrails, power unit
Signal output: 4 -20 mА and interface RS232, RS485
Power supply: 220V, 50 Hz; 10 V/A(max)
Protection class rating: transmitter and receiver: IP 54
telltale and computing device and и power unit: IP 44
Instrument is persistant to exposure of relative humidity of ambient atmosphere 95 ±3% at +35°С.
Instrument allows on-line mapping of current concentration of hydrocarbon gases onto display and generating of sound-and-light indication of hydrocarbon gases threshold concentration excess, and also echoing history (repository) of emissions number per day (up to 32 days), per month (up to 3 months), max concentration of hydrocarbon gases at each emission and emissions duration, and power cutoff and gaging paths closing.
Explosion protection — 1ЕхibIIAТ4.
DID-МТ 1.000-Ех does not have analogies in Russian Federation or abroad the country.
