Flameproof Ultrasonic Gas Leak Detector | GDU-01 Ex-d

Features:

• The GDU-01 Ultrasonic Gas Leak Detector is not a volumetric measuring detector, but detects the ultrasonic noise generated by escaping pressurised gas. Ultrasonic noise is generated when leakage occurs at sonic velocity, which requires a driving pressure of at least 2 barA.
• The detected sound is proportional to the leak rate (mass flow rate). In basic terms, the greater the leak rate (pressure/ velocity/volume), the greater the ultrasound emitted.
• The GDU-01-Exd is factory calibrated and has no moving or replaceable parts, it responds instantly to leaks operating over a wide dB range.
• The GDU-01-Exd is a 3 wire 4-20mA Ultrasonic Gas Leak Detector and alarm levels can be selected and adjusted at the control system.
