Integral Gas Feed 11 Caldos27 thermal conductivity analyzer for the measurement General Data 12 of binary gas mixtures with different thermal conductivity Ar in O2, H2 in Ar, CH4 in N2.

3 Electrical Connections 14. Gas Connections 16 Electrochemical oxygen sensor for the measurement of O2. Certifications 18 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-10/100 BASE-T interface (for service and configuration purposes).

4 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. Housing Design The housing for the EL3020 gas analyzer Model is designed as a 19-inch housing with 3 height units and degree of protection IP20. Note Regarding the Performance Characteristics of the Analyzers The performance characteristics of the Analyzers have been determined according to the international standard IEC 1207-1: 1994 Expression of performance of gas Analyzers . They are based on N2 as the associated gas. Compliance with these characteristics when measuring other gas mixtures can only be assured if their composition is known.

Selectivity measures to reduce associated gas effect (optional): Incorporation of interference filters or filter cells, internal electronic cross-sensitivity correction for one sample component by other sample components measured with the gas analyzer . Temperature Effect Ambient temperature in permissible range At zero-point: 2 % of span per 10 C. On sensitivity without thermostat: 3 % of measured value per 10 C. On sensitivity with thermostat (optional): 2 % of measured value per 10 C. Thermostat temperature = 55 C.
