Honeywell Vertex M - 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 M 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:
l
Sample lines to all monitored locations
l
Flow connections through quick-connect ports in bulkheads on top of unit
l
Moving cable and connectors
l
Vacuum pumps
l
Analyzers incorporating manifolds, Chemcassette™ and filters
l
Flow controlling proportional valve
l
Top exhaust port
There are 24 inlets, one for each monitored location. One exhaust port is also located on top of
the Vertex M cabinet.
2.7 Chemcassette™ Detection System
The Chemcassette™ Analyzer module is a self- contained, microprocessor controlled analyzer
that occupies one slot in a Vertex M. Sample lines and the vacuum source are connected to the
Chemcassette™ via a single 10-tube connector.
The system powers up in the same state as when powered down. Data is stored in the module’s
memory until the data acquisition computer retrieves it.
The Vertex M Analyzer modules use the Honeywell Chemcassette™ optical detection system.
Analyzer modules sample and detect a specific gas or family of gases.
