msa ultrasonic gas detector

UltraSonic EX-5Ultrasonic Gas Leak Detector Instantly detect pressurised gas leaks in a 20 meter radius with this high-precision, omnidirectional, ultrasonic leak detector

Responds to the Sound Not the Leak The UltraSonic EX-5 is a non-concentration based gas detector used to

detect leaks from high pressure systems. The UltraSonic EX-5 responds to

the airborne ultrasound generated from gas releases in open, well

ventilated areas, where traditional methods of detection may be

unsuitable or dependent on ventilation.

Immunity to Background Noises Immune to audible background noises, such as compressors or heavy

machinery, the EX-5 can be configured to filter short timescale noises that

would otherwise trigger nuisance alarms. At the same time, setting the

alarm trigger level above the ultrasonic background noises ensures

immunity to other noises sources.

Self-Test System for Full Failsafe OperationSENSSONIC™ self-test technology provides a full test of the UltraSonic

EX-5 ultrasonic gas leak detector every 15 minutes. This ensures that the

microphone and the electronics are working to their best of ability.

KEYBENEFITS• Unaffected by changing weather

conditions; rain, fog or solar radiation

• Self-test functionality every 15

minutes ensures failsafe operation

• Microphone technology detects leaks

through the sound ensuring rapid

response at the speed of sound

• Durable design withstands corrosive

environments that contain poisonous

or highly concentrated gases

• Stand alone operation or combine with

traditional detection methods
