7.1 Splitting multiplexers and
demultiplexers
Splitting multiplexers and demultiplexers are used when several measuring path are co-
trolled by one LD500 analyser or several gases are measured.
The following figures show different configurations where splitting multiplexers and de-
multiplexers are used.
Note: When ordering a splitting multiplexer or demultiplexer, the laser module type
must be specified.
F
igure 7.1. Splitting multiplexer MX10nL or demultiplexer MXn01L.
F
igure 7.2. One laser module controls two paths. A multiplexer MX102L is used.
