MSA Ultrasonic Gas Detector
1. UltraSonic EX-5
Ultrasonic 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
KEYBENEFITS
•
detect leaks from high pressure systems. The UltraSonic EX-5 responds to
the airborne ultrasound generated from gas releases in open, well
conditions; rain, fog or solar radiation
•
Unaffected by changing weather
ventilated areas, where traditional methods of detection may be
Self-test functionality every 15
unsuitable or dependent on ventilation.
minutes ensures failsafe operation
Immunity to Background Noises
• 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
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 Operation
SENSSONIC™ 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.
