The GasGuard O2 utilizes a proven
galvanic cell type oxygen sensor.
With a large capacity electrolyte
reservoir for exceptional cell life,
the GasGuard O2 electrochemical
cell is designed with excellent
chemical durability, and is not
affected by interference gases such
as carbon dioxide.
Every GasGuard O2 sensor comes
equipped with an internal temperature
control designed to perform in the
harshest of areas. The controlled
environment provides temperature
and moisture control for extended cell
life. The high-quality injection-molded
polycarbonate enclosure offers
excellent chemical corrosion
protection and high impact resistance.
The GasGuard O2 provides an
industry standard linear 4/20 mA
output signal compatible with most
gas detection systems and PLCs.
The output signal is not affected by
drastic temperature variations such
as washdown and defrost cycles,
and is minimally affected by
barometric pressure changes.
Applications
- Air Quality Monitoring
- Refrigeration Systems
- Confined Space
- Tank Rooms
- Food Processing
- Breweries
Benefits
- Low cost of ownership
- Simple operation
- Rugged and reliable
No more hidden “adder” costs for stainless
steel or heated boxes. The standard
GasGuard O 2 sensor is designed to work
anywhere, and at a lower base-model price
than most of our competition. With the
rugged extended life cell, the GasGuard O 2
sensor with give you years of trouble-free
operation resulting in an extremely low cost
of ownership. We typically recommend a
19.5% alarm setpoint for oxygen deficiency
monitoring for personnel protection. 23.5%
is usually desirable for oxygen enrichment
situations.
From hot mechanical rooms, to acid
washdowns of processing areas, the
GasGuard O 2 is prepared to survive in just
about any harsh industrial condition. Every
circuit board is sealed forever in potting
compound, protecting electronic
components and copper tracing from
corrosion. A specially vented chemical-
resistant polycarbonate enclosure protects
the sensor from accidental damage,
weather and even direct hose-hits from
clean-up crews. A stainless steel enclosure
is also available for applications that require
it.
