The GDS-58DXP sample draw
gas monitor is an ideal solution for
ambient gas detection applications
where the monitored location is
unsuitable for the direct installation of a fixed gas detector due
to enviromental, access or other
reasons. The GDS-58DXP sample
draw monitor is designed to detect
a wide range of toxic and combustible gases in potentially hazardous environments. The monitor
operates on +24VDCvolts DC and
includes an optional 110/220VAC
power supply. Outputs include
dual industry standard 4-20mA
analog signals as well as a MODBUS
port. Optional alarm relays allow the
GASMAX DSX to communicate with
a wide range of industry devices and
system controllers.
Wide Variety of Available Sensors
The GASMAX DSX supports both
local and remote electrochemical and
infrared combustible sensors. Several
electrochemical sensors, including
hydrogen sulfide are available in low,
medium and high ranges.
Non-Intrusive User Interface
The GDS-58DXPfeatures non-intrusive magnetic switches that
allow complete system configuration,
regular calibration and product maintenance to be performed in the field
without compromising the explosion-proof rating. The display screen always shows the current calibrated level
of gas present at the sensor.
Flexible Output Options
In addition to dual industry-standard
4-20mA current loop outputs, a built-in
isolated RS-485 two-wire MODBUS®
interface is available to communicate
with controllers, PLCs or large DCS
system. A special Modbus Wiring
Junction Box option makes it possible
to easily create the daisy chain wiring
for power and Modbus signal.
Certifications
The GDS58-DXP is built around the
CSA certified GASMAX DSX gas
monitor and is designed for use in
hazardous areas using CSA and UL
certified flame arrestors, seals and
enclosures.
Applications
The GDS58-DXP is ideal for power
plants, refineries, tank farms, chemical
plants, compressor stations, pipelines
and other industrial installations where
fixed gas detection is required for
user safety and equipment protection.
