Airborne Ultrasound Sensors
Airborne Ultrasound Sensors: Hear the Invisible Through the Air
Non-Contact Detection for Leaks and Electrical Safety
In many industrial environments, the most critical faults—like compressed air leaks or electrical arcing—occur in open spaces or hard-to-reach areas. Airborne Ultrasound Sensors by SDT act as “electronic ears,” picking up high-frequency turbulence and ionization from a distance. As the official partner in Iraq, Rhein Global provides these specialized sensors to help your team find what the human ear cannot hear.
Why Choose Airborne Ultrasound Sensors?
-
Safe Distance Monitoring: Detect high-voltage electrical faults (Corona, Arcing, Tracking) from a safe distance, keeping personnel away from “arc flash” zones.
-
Rapid Large-Scale Scanning: Quickly scan hundreds of meters of overhead piping or large tank farms for pressurized gas leaks without needing direct contact.
-
Directional Precision: Equipped with specialized horns and parabolic dishes, these sensors can pinpoint a tiny leak in a noisy factory by focusing only on the source.
-
Zero Downtime Inspections: Conduct comprehensive leak audits and electrical inspections while your plant is fully operational.
The Airborne Sensor Lineup
We offer a variety of specialized non-contact sensors for different industrial challenges:
-
Flexible Wand Probes: Ideal for reaching into tight gaps, behind safety guards, or inside complex machinery.
-
Extended Distance Horns: Boosts the detection range for overhead compressed air lines and steam headers.
-
Parabolic Dishes (The ParaDish): Designed for extreme long-range detection (up to 100 meters), perfect for inspecting high-voltage transmission lines and outdoor substations.
-
Internal Airborne Sensors: Permanent sensors for 24/7 monitoring of electrical cabinets to detect early-stage discharge.
Strategic Applications in Iraq’s Energy & Industry
-
Compressed Air & Gas Leak Management: Significantly reduce energy costs in refineries and factories by finding and fixing “silent” leaks.
-
Substation & Transformer Safety: Identify Partial Discharge in high-voltage assets before they lead to catastrophic fires or power outages.
-
Vacuum Leak Detection: Quickly find leaks in vacuum systems, which are traditionally much harder to detect than pressurized leaks.
-
Building Envelope & Seal Testing: Use in combination with ultrasound transmitters to check the tightness of cleanrooms, hatch covers, and large storage tanks.
