Description

EL3020 ABB Continuous Gas Analyzers

Stability
The following data apply only if all influence factors (e.g. flow rate, temperature, atmospheric pressure) are constant. They relate to the smallest measurement range.

Linearity deviation

≤ 1 % of span
Repeatability
≤ 0.5 % of span
Zero drift
≤ 1 % of span per week
Sensitivity drift
≤ 1 % of measured value per week
Output fluctuation (2 σ)
≤ 0.2 % of span at electronic T90 time (static/dynamic)
= 5/0 sec
Detection limit (4 σ)
≤ 0.4 % of span at electronic T90 time (static/dynamic)
= 5/0 sec

Measurement principle
Potentiometric measurement; zirconium dioxide cell for determination of the oxygen concentration in accordance with Nernst’s equation; reference gas: ambient air.The analyzer is used for the continuous measurement of oxygen in pure gases (N2, CO2, Ar). The measuring cell is catalytically inactivated to the extent that flammable carrier components in stoichiometric concentrations only negligibly reduce the oxygen value.

Sample component and measurement ranges
Sample component
Oxygen (O2)
Measurement range quantity and limits
2 measurement ranges
Measurement ranges are freely adjustable within the 0–1 ppm
to 0–250,000 ppm O2 range; they are factory-set to 0–1/
0–10 ppm O2.
The following measurement data refer to a measurement span of 100 ppm O2 with a regulated flow rate of 8 ± 0.2 l/h.

Notes
Both drawings show examples for the I/O modules equipment.
I/O module connection:
– The maximum capacity of terminals for stranded or solid conductors is 1 mm2
(17 AWG).
– The stranded conductor may be tinned on the tip or twisted for simplified connection.
– When using wire end ferrules the total section should not exceed 1 mm2 , i.e. the maximum stranded conductor section is 0.5 mm2. The Weidmüller PZ 6/5 crimping tool must be used for crimping the ferrules. Functional scope of the Ethernet interface:
– Communication with configuration software ECT for gas analyzer configuration and software update.
– QAL3 data transfer if the QAL3 monitoring option is integrated in the gas analyzer.
