MSA UltraSonic IS-5 and UltraSonic EX-5

The UltraSonic IS-5 and EX-5 are non-concentration based gas detectors used to detect leaks from high-pressure systems with a maximum coverage radius of 20 meters. They respond to the airborne ultrasound generated from gas releases in open ventilated areas, where traditional methods of detection may be difficult.
The intrinsically safe UltraSonic IS-5 is suited for installations restricted to low power (< 1 W). The explosion-proof UltraSonic EX-5 features the SenssonicTM patented self-test for full failsafe operation and a three digit LED display showing actual ultrasonic level value (in dB) and alarm indication.
Standard 4–20 mA output with HART capability and output relays can control additional action in case of alarm or fault condition.

For more information, please see leaflets 07-491.2 and 07-492.2.
