Millennium Air Particle Monitor
(APM)
The Net SafetyTM Millennium Air Particle Monitor
(APM) is the only infrared optical monitor that is
certified for use in hazardous areas for constant,
reliable monitoring of ambient air for products
of combustion such as smoke, oil mist, carbon,
dust, and ash.
This unique product is explosion proof —
ideally suited for a wide variety of industrial
applications. Proven installed base includes
Class I, Division 1 areas requiring accurate air
particle monitoring such as air ducts, battery
rooms, engine rooms, compressor stations,
offshore living quarters, and HVAC air intake
points.
Explosion-proof, Class I, Division/Zone 1
approved
Operating temperature range -40 °F to 167 °F
(-40 °C to 75 °C)
4–20 mA analog and relay output congurations
Remote sensor separation - 2,000 ft (600 m) and
a variety of duct mount assemblies available
Intuitive menu system, zero in 60 seconds from
start to nish
Field adjustable sensitivity settings
Not affected by high volume air velocity
Multi-language, bright scrolling LED display
allows operators to ne tune at installation site.
The advanced sensor design has several performance features;
it uses a powerful infrared lamp and no mirrors, making the
optics resilient to the adverse effect of dirt. The instrument’s
eld adjustable zero level of obscuration and multiple sensitivity
settings allow for ne tuning to optimize performance and
eliminate false alarms. Additionally, the sensor can be equipped
with a duct mounting kit, pipe mounting kit, and pipe
extensions to suit many applications.
Millennium Air Particle Monitor (APM)
The Millennium Series controller is an innovative line of
explosion proof industrial detectors. Its microcontroller
provides fast, accurate, and continuous monitoring in
hazardous area environments. The 4–20 mA analog signal and
FORM-C mechanical relays easily integrate into industrial safety
systems. The compact controller with power disconnect switch
simplies maintenance, a scrolling LED simplies calibration
and conguration, while meter jacks facilitate current loop
monitoring.
The Net Safety Millennium APM is market proven within
a variety of specialized applications worldwide, providing
superior performance and effectiveness.
Applications
Gas compressor stations, FSPO/tanker hull chambers, gas
turbine engine enclosures, marine battery rooms, engine
rooms, duct monitoring, chemical storage, industrial
manufacturing, and HVAC systems.
