Measurement Range Data
Quantity
1 range per sample component.
The measurement range is freely adjustable within a range ratio
of
≤
1: 5 relative to the factoryset measurement range.
Largest Measurement Range
0 to 100 Vol.% or 0 Vol.% to saturation or 0 Vol.% to LEL.
Measurement ranges within ignition limits cannot be provided.
Measurement Ranges with Suppressed Zero-Point
Differential measurement with flowing reference gas.
Max. suppression ratio of 1:10 depending on the base level.
Influence Effects
Flow Effect
Flow rate in the 20–100 l/h range: 0.5 % of span at a flow rate
change of
±
10 l/h
Pressure Drop at Flame Barriers
Sample Gas or Reference Gas Inlet: Approx. 40 hPa at a flow
rate of 50 l/h. Purge gas inlet: Approx. 20 hPa at a flow rate of 10
l/h
Associated Gas Effect / Cross Sensitivity
Analyzer calibration should be based on an analysis of the sam
ple gas. Selectivity measures to reduce associated gas effect
(optional): Incorporation of interference filters, filter vessels or
internal electronic crosssensitivity correction or carrier gas cor
rection for a sample component by other sample components
measured with the analyzer unit.
Temperature Effect
Ambient temperature in permissible range
–
At zeropoint:
≤
1 % of span per 10 °C;
for ranges smaller than Class 1 to Class 2:
≤
2 % of span per 10 °C
–
On sensitivity with temperature compensation:
≤
3 % of measured value per 10 °C
–
On sensitivity with thermostat effect at 55 °C (optional):
≤
1 % of measured value per 10 °C
Air Pressure Effect
On sensitivity with pressure correction by means of integral
pressure sensor:
≤
0.2 % of measured value per 1 % barometric
pressure change.
Pressure sensor working range: p
abs
= 600–1250 hPa
Dynamic Response
Warm-Up Time
Approx. 30 minutes without thermostat; approx. 2 hours with
thermostat.
