MSA UltraSonic™ EX-5 Gas Leak Detector

The UltraSonic EX-5 Gas Leak Detector is used to detect airborne leaks from high-pressure gas systems. The detector responds to the ultrasound generated from gas releases in open, well-ventilated areas, where traditional methods of detection may be unsuitable or dependent on ventilation. Because the UltraSonic Detector responds to the source of a gas release rather than the dispersed gas, it is unaffected by changing wind directions, gas dilution, and the direction of the gas leak. With its wide coverage radius, a single detector can monitor a relatively large area.

The UltraSonic EX-5 Detector is immune to many false signals and can be configured to filter short timescale ultrasonic noise that can produce nuisance alarms. Frequencies below 25 kHz are removed by a high pass filter, effectively eliminating interference from audible and low frequency ultrasonic noise. At the same time, setting the alarm trigger level above the ultrasonic background noise ensures immunity to other noise sources. The result is a reliable method of detection, able to monitor environments with high levels of ultrasound such as turbine rooms and compressor stations.

The UltraSonic Detector also features the Senssonic™ patented self-test for full failsafe operation. This self-test checks the electrical integrity of the device and microphone every 15 minutes and ensures that the detector is operational at all times. In addition to a 4-20 mA output, the UltraSonic Detector is available with ModBus or HART to enable asset management and process improvement.
