Gas Detection

Searchzone Sonik™

The Sound of Safety in Any Environment

Search. Detect. Protect.

ULTRASONICALLY

The Hazard is Blowing in the Wind

Field studies have shown that around 30% of flammable gas
leaks can go undetected because the gas is blown away by
the wind. But if the weather conditions change, and the wind
drops, the chances are that a flammable gas cloud might
build up and trigger incidents and hazards.

Since traditional point and open-path devices cannot detect

leaks unless the gas reaches the sensor, the need arose for
a revolutionary and complementary type of gas detection
technology. Instead of waiting for the gas to reach the detection

device, an ultrasonic detector operates by responding to the

sound created by high-pressure gas leaks at source.

Searchzone Sonik – Safe and Ultrasound

The new Honeywell Searchzone Sonik is a robust and reliable gas leak detector that will ef ficiently “hear”

the loss of containment of any high-pressure gas within its listening zone. An advanced, SIL 2 certified,

hazardous area ultrasonic gas leak detector, the Searchzone Sonik responds to the ultrasonic sound pressure

level produced by pressurized gas leaks and is therefore unaffected by environmental conditions.

Searchzone Sonik is factory calibrated. Its robust sealed design with no moving parts and the solid-state sensor allow for

mounting in any orientation, even in the harshest environments. The gas leak detector will respond quickly to a gas leak within

a sensing range radius of typically 20m (65 ft), dependent upon background noise. The intelligent background noise detection

system allows the detector to be set up for maximum sensitivity while Focus Mode means that the detection area can be

restricted to only include the hazard being monitored. This way you have confidence that you’ll always stay safe and ultrasound.

How do you sense what you can’t hear?

Since gas does not need to come into contact
with their sensors, ultrasonic (or acoustic)
detectors respond instantly upon “hearing” the
distinct sound pattern of a leak, operating at a
frequency outside the range of human hearing.

Unaffected by air flows and adverse weather
conditions, they are particularly suited to open and
well-ventilated areas, such as floating production
storage and offloading vessels, gas turbine power
plants, compressor stations, gas storage facilities,
petrochemical processing plants, refineries, or
offshore and onshore oil and gas installations.

Normal Mode will detect ultrasonic noise from a wide angle, which is

ideal for areas that have lower or constant levels of background noise.

However generally you will generally know where

the potential source of the leak is.

That is where Searchzone SonikTM comes into it’s own. Switch

to Focus Mode (patent pending) and Searchzone SonikTM will

enable special algorithms that effectively screen ultrasonic noise

generated outside of the specific area of interest. This dramatically

reduces the risk of alarms from spurious noise sources.

You Own the High Ground

Suppose you are servicing an ultrasonic device that complements the point and open
path gas detectors of an offshore platform. It’s raining, the wind is blowing heavily, and
you’re on a slippery deck, a long way below the Searchzone Sonik you need to reach.

Concerned about working at heights, in awkward positions that may even threaten your
safety? Think again. Thanks to an easy-to-use mobile app and a dedicated testing tool,
you can connect from ground level and test the Searchzone Sonik remotely, without
exposing yourself to hazards. All you need to do is to stand on the deck, connect with
your smartphone, and use the testing tool to check the detector’s response – it’s as
easy as 1, 2, 3 to have the high ground.
