Launch to Detect Interconnect (cable)
Launch Unit:
• Analyzer detachable from process
interface for Off-Line calibration / service.
• Flanged O-Ring Alignment
• Flanged Metal Bellows Seal Alignment
• Flow Cell
• Isolation Flanges
• By-Pass Piping
• Custom designs for specic applications.
Detect Unit:
• Detect Electronics
Housing
• Detector Assembly
• The Launch Unit and Detect Unit are connected to each other via a Tray Rated 4-pair shielded twisted
pair cable.
• The Launch Unit requires a single 24VDC power supply (by customer or via optional Power Supply
Unit).
• Nitrogen purge gas is required to prevent ambient oxygen ingress however, for other target gases it
may be possible to use Instrument Air for purging.
• The Process Interfaces are available in various formats, sizes and materials to suit the desired
measurement/installation.
• The available Remote Interface Unit (RIU) can be located typically up to 100m (330ft) away from the
Launch Unit. The RIU also requires a 24VDC power supply. The RIU connects to the Launch Unit on
Ethernet (10-base-T 10/100) via CAT5e eld rated cable.
• The available Universal Remote Display (URD) can be located typically up to 40m (120ft) away from the
Launch Unit. The URD requires an AC power input that is connected to a universal power supply with
24VDC output power supply (for the analyzer). The URD connects to the Launch Unit via multipair
sheilded twisted pair cable.
