SZSK-SMGXX Searchzone Sonik Ultrasonic Gas Leak Detector, SST, M25 with Adjustable Mount and Sunshade by Honeywell Analytics

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.

The new Honeywell Searchzone Sonik is a robust and reliable gas leak detector that will efficiently "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 airflows 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 Sonik™ 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.

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.
