0/4-20 mA burden 270 Ω for every measuring range, electrically isolated; output
voltage max. 15 V (ex works).
Switchable max. burden 800 Ω, output voltage max. 30 V.
Output current limiting adjustable 20 mA to 22 mA
20.5 mA ex works
0-10 V DC, burden >100 KΩ for range 0-100 % isolated.

No influence up to 50 °C [122 °F]
The oxygen reading varies in direct proportion to changes of the barometric
pressure.
No influence from 0.6-1.5 bar abs. at PMA 50 EX/P/PD(-1-50) with process pres-
sure compensation
Variation in gas flow between 0-60 Nl/h air will cause a difference of
< 0.2 vol.% O

Max. 1.1 bar abs.standard or in case of purging up to 1.5 bar abs.
(Minimum inlet pressure is required for necessary gas flow, PMA50 EX has no inte-
grated pump)
Outlet of analyzer must discharge freely into atmosphere
or 0.6 to 1.5 bar abs. at version PMA 50 EX/P/PD(-1-50) with process pressure com-
pensation
Min. 10 Nl/h up to max. 60 Nl/h adjustable externally via flow meter (no flowmeter
inside)
