Table 7- 6 Technical data – measuring behavior
Measuring behavior
Output signal variation < 1% of smallest possible measuring range
according to rating plate with an electronic delay
of 1 s
Measured value drift < ± 2%/month of respective span
Repeatability < ± 3 % of respective span
Linearity deviation < ± 2% of respective span
Accuracy
5)
The accuracy is the geometric total of the output
signal variation, drift, repeatability and linearity
deviation with constant influencing variables.

Influencing variables
3)
Ambient temperature < 2%/10 K referred to the respective span
Sample gas pressure With pressure compensation switched on:
< 0.2% of respective span /1% change in
pressure
Auxiliary gases
Catalytically inactive sensor:
approx. 1 vpm O

; CO and CH
4
exhibit
a smaller cross-interference; higher hydrocarbons
are negligible
Catalytically active sensor:
only gases with non-flammable auxiliary gas
components may be sampled!
Sample gas flow < 2% of smallest possible span according to
rating plate with 10 ml/min change in flow within
the permissible flow range
