Sampling System - Honeywell Vertex VC 4 User Manual

Sampling System

The Vertex™ VC4 is a monitoring center for sampling lines from sample locations. As they apply to the Vertex™
VC4 System, the words point, line and location require definition:
• A location is a place to be monitored
• Sample atmosphere runs from the location to the Vertex™ VC4 System via a line
• Each of the 4 sample tubing connections on the Vertex™ VC4 System corresponds to a point. A sample line
can be connected directly to a single
The system draws air simultaneously from all locations. Two different types of flow are:
• Transport flow: high-velocity, large-volume air movement through the lines
• Sample flow: air admitted to the Chemcassette® detection system
The high speed of transport flow allows rapid monitoring and response time when using long lines from
monitored locations to the Vertex™ VC4 System. A small portion of the transport flow (sample flow) is analyzed
to determine concentration levels.
The complete sampling and monitoring system consists of the following components:
• Sample lines to all monitored locations
• Flow connections through quick-connect ports on back of unit
• Vacuum pump
• Manifolds, Orifices, Chemcassette® and filters
• Flow controlling manual needle valve
• Exhaust port
There are 4 inlets, one for each monitored location. One exhaust port is also located on top of the Vertex™ VC4
cabinet.
