Infrared gas analyser DID 1.000 – Ех

ASSIGNMENT - permanent monitoring of pre-explosion ratio of hydrocarbon gases at fabrication systems, 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 receiver.


Specifications

Measuring range of hydrocarbon gases? concentration: 1 — 100 LET x m
(range of registered concentrations for measurement right-of-way /100m/ …..0.01 — 1 LET)
Measuring accuracy: ±5%
Temperature of ambient medium: from -40°С to +70°С
Gaging path length: 20 — 100 m
Speed of instrument, less than: 8 s
Device components: transmitter, receiver, telltale and computing device, guardrails, power unit
Output signal: 4 -20 mА and interface RS232, RS485
Power supply: 220V, 50 Hz; 8 V/A(max)
Protection class rating: transmitter and receiver: IP 54
