Signalization transmitted by the current loop 4-20 mA
Measurement:
The measure concentration is directly proportional to 4-20 mA current output
Exceeding the range of measured concentrations:
Current output ranges from 20-22 mA
End of valid calibration:
Current output transmits the actual measured concentration for 9 s in a 4-20 mA range and
for 1 s 2 mA current
Malfunction:
Current output will be set to 0,5 mA
Mainternace:
Current output will be set to 1 mA
3.
Conversion between volume concentration and lower explosive limit of methane
% DMV
– concentration level of the lower explosive limit in %
% obj
– gas volume sample
4,4
– lower explosive limit of methane (4.4% vol.)
