Banshee343 Ultrasonic Gas Leak Detector
Wide Area Coverage For Toxic and Combustible Gases
“SMART” Gas Detector Series
The Banshee343 is an advanced leak detection system utilizing four
ultra-sensitive acoustic sensors which constantly monitor wide areas for
ultrasound generated from the release of pressurized gas. This advanced
gas sensing technology never requires calibration or replacement, for
the life of the instrument.
Ideally suited for monitoring well ventilated outdoor applications,
the Banshee343 has been engineered to withstand even the most
extreme conditions. Performance is not affected by inclement weather,
wind direction, leak direction or any potential gas dilution with an
instantaneous response to all gas types.

Instantaneous Response To All Gas Leaks
(LEL or ppm)
Certified temperature range of -55°C — +85°C
‘SonicCAL System’ — Automated Self Test
and Sensor Cleanse, Failsafe Operation and
Maintenance Free
Widest Area of Coverage, 40 Meter Radius
Through Four Independent Sensors
Four Multi-Directional Sensor Heads
Quad, independent sensor heads provide the widest overall
detection range and reduce the possibility of obstruction,
common with a traditional single microphone design.
Field-proven Ultrasonic Sensor Principle
Advanced acoustic sensors utilize the proven method of
ultrasonic gas leak detection to protect your plant and
personnel, with hundreds of installations worldwide.
Ultrasound is generated from pressurized leaks of any gas
type, providing simultaneous flammable and toxic gas
coverage. The presence of a concentrated gas cloud for
detection is never required, making this technology ideal
for wide area coverage in outdoor applications.
Sealed Ceramic Sensor Housing
Piezo-electric sensor heads are encased in a virtually
indestructible ceramic housing and sealed against
temperature, moisture and industrial contaminants.
4-20 mA Analog, Relay, RS485 Digital Interface
Certified Worldwide for Hazardous Locations
Widest Dynamic Range Available, 50db — 160dB
Innovative Mapping Tool Helps Operators Achieve
Optimum Performance At Site Location
Programmable Time Delays to Allow For
False Alarm Sources (Pressure Venting, etc)
Sensor Design - They Just Keep Working
Each sensor is completely free of moving parts and will
not age, will not drift, and will never need replacing under
normal working conditions. Maintenance free protection
with proven reliability.
Patented Failsafe ‘SonicCAL System’
Our full diagnostic system runs an automated broadband
self-test every 15 mins applying a true pressurized gas leak to
confirm each sensors detection capability and removes any
potential external contaminants such as sand, oil or dust.
Built for Extreme Conditions
Dealing with extreme heat or cold? We’ve got you covered
with an operational temperature ranges of -55°C to +85°C!
Corrosion resistant stainless steel housing is available, and
every unit is rated IP66/67.

ULTRASONIC DETECTION OVERVIEW
Ultrasonic (acoustic) gas leak detection technology
functions through the constant monitoring of wide
areas by advanced acoustic sensors specially tuned
to process ultrasound emitted from pressurised
gas leaks. This detection technology has several
advantages: it does not have to wait until a gas
concentration has accumulated to potentially
dangerous concentrations, it does not require
a gas cloud to eventually make physical contact
with a sensor, and the response is instantaneous
for all gas types (FIG.3).
Simply put, the ultrasonic leak detector only
triggers an alarm when inaudible, ultrasound is
detected (between 25 - 100 kHz) — which is only
produced with the release of highly pressurized
gas (FIG.2). This makes for extremely reliable and
efficient performance by the detection system as
there is no poisoning of sensors, it never requires
field calibration, and all background noises are
accurately filtered or eliminated through time
delay settings.
The Net Safety Banshee343 detects deadly gas leaks at the speed of sound with wide
area coverage without being affected by inclement weather, wind direction, leak
direction or any potential gas dilution. When utilized together with Net Safety point
gas detection and our optical flame detection, a complete and comprehensive safety
system is ensured (FIG.1).
