产品描述:

Ultrasonic gas leak detectors complement traditional gas detection methods by listening to the ultrasound emitted from a pressurised release. Detection is not affected by wind direction or gas dilution hence the ability to detect leaks at an early stage can be achieved.
 
Features
Fast response
Instant On-line airborne leak detection
Encapsulated resonant sensor
Continuous Active Measurement
Suitable for hazardous areas
ATEX proved, intrinsically safe
Direct connection to DCS / PLC / F&G
Fully sealed and glanded construction
Detection Coverage
>60 dB range, no field set-up required
>30m (100 ft) detection range
 
Application
The GDU may be utilised in a wide range of installations:
Offshore Gas / Oil Platforms
FPSOs
Onshore Gas Receiving Terminals
Underground Gas Storage Facilities
Gas Transmission Networks
