GasEye Cross Duct SG and MG
Operating instructions, 05/2021
Additional build-in features:
Automatic gain control (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
The system is composed of two units: central unit (with a transmitter) and receiver
unit. The receiver unit is connected to the central unit with a hybrid loop cable. The
standard loop cable length is 10m (up to 150m). The system is connected to the
customer DCS with the customer cable (standard length is 5m). It is also used for
powering the device. Ethernet cable is provided for commissioning/service/diagnostic
purposes (standard length 10m). System can be fully parametrized and tested via
WebServer. Additional cables for industrial protocols must be provided by the
customer.
