Measuring Technology (Analyzers)
The following analyzers are available for selection:
• Uras26 infrared photometer for the measurement of infraredactive gas components e.g. CO, NO, SO2
• Magnos206 oxygen analyzer for the measurement of O2 in process gas or in N2
• Caldos27 thermal conductivity analyzer for the measurement of binary gas mixtures with different thermal conductivity e.g. Ar in O2, H2 in Ar, CH4 in N2
• Electrochemical oxygen sensor for the measurement of O2
The electrochemical oxygen sensor can only be used in combination with the Uras26 infrared photometer.
The Magnos206 oxygen analyzer and the Caldos27 thermal conductivity analyzer can also be used in combination with the Uras26 infrared photometer. Integral Gas Feed
The integral gas feed (option) is available in two versions. It either includes
• the micro-filter and flow sensor modules
• or the micro-filter, solenoid valve, pump, coarse filter, capillary tube and flow sensor modules.
Electrical Interfaces
The electrical interfaces for the output of measured values and communication with external systems include
• The integrated Ethernet-10/100BASE-T interface (for service and configuration purposes) as well as the integrated I/O modules depending on the functional range and order
• Analog output module with 2 analog outputs,
• Digital I/O module with 4 digital inputs and 4 digital outputs and
• Modbus module with RS485 and RS232 interfaces.
