Paramagnetic Oxygen Analyzer (Flameproof Type) MG8E
Country: · Model: MG8E
The MG8E paramagnetic oxygen analyzer in the flameproof Ex d IIBT4X version measures O2 from 0–1 to 0–25 vol%, with 3 programmable ranges. It works in flammable mixtures and at low oxygen concentrations, with ±1% span repeatability.

Description
The principle is the same as in the MG8G, a magnet attracts oxygen, so flammable components of the mixture do not interfere. The differences lie in the lower range limit and the construction, as the Ex d IIBT4X enclosure permits installation in a hazardous area. The output is 4–20 mA DC into a load up to 550 Ω, and contact inputs switch the range and start calibration. Sample gas flows at 300–800 ml/min ±10% of the set value, standard 600 ml/min, at about 7 kPa at the inlet and 0–50 °C. Auxiliary N2 is needed at 350–500 kPa. Supply is 90–127 V AC, 48–63 Hz. Linearity and repeatability are ±1% of span and the 90% response takes 3 s.
How to choose
Take the MG8E when oxygen is scarce, since the scale starts at 0–1 vol%, or when the analyzer goes into an area that calls for a flameproof version. If a range from 0–5 vol% is enough and the area is ordinary, the MG8G will do. Pick the working flow within 300–800 ml/min, and keep condensate out of the sample gas.

FAQ
What is the lowest range of the MG8E?
The O2 measurement range runs from 0–1 to 0–25 vol%, and 3 ranges can be programmed.
What explosion protection does the MG8E have?
The enclosure is Ex d IIBT4X, a flameproof type, so the analyzer can be installed in a hazardous area.
What auxiliary N2 pressure is required?
350–500 kPa, with a flow of about 35 ml/min.
What ambient temperature is allowed?
From -5 to 50 °C, and the instrument is mounted indoors on a panel or a wall.
What sample gas flow does the MG8E need?
300–800 ml/min ±10% of the set value, standard 600 ml/min, at about 7 kPa at the inlet.
