Status alarm
For minimum flow alarm, transmitter temperature < 40 °C, light source
defective, measuring system defective, failure of tension: LED-
indication and contact outlet: change-over contact, potential-free, max.
24 V DC, 0.5 A
Response time for 90% value
< 5 seconds at 60 Nl/h air
Accuracy after calibration
Deviation: analogue signal output = ±1 % of span 2.5 – 25 % / Digital
indication = ±0.1 vol% O

, = ±2 % of span 1%
Reproducibility
Analogue output = < 1 % of span /
Digital indication = ± 0.1 vol% O

Influence of ambient temperature
No influence up to 50°C
Influence of barometric or outlet pres-
sure
The O

indication varies proportionally to the barometric or outlet
pressure
Influence of the sample gas quantity Variation between 0-60Nl/h air will cause a change of indication
