| Electrical Characteristics |
|
| Power input: | 24 VDC nominal (19 – 30 VDC) |
| Power consumption: | < 20VA |
| Additional build-in features |
|
| Automatic gain control (AGC): | AGC ensures correct gas measurement even at high dust loads resulting in loss of optical transmission down to 0.5%. AGC operates fully automatic with no need for manual adjustment of the signal gain under any process conditions. |
| Self-calibration features: | Internal reference gas compartment is used for closed loop control of the zero and span drift |
