LD 300 leak detector
If gases escape through leaks ultrasonic noises are generated. By means of the LD 300
leakages can be detected in the ultrasonic range even from distances of several meters.
LD 300 transforms the inaudible signals into a frequency which can be
identified by means of the provided sound-proof headset. In depressurized
systems an ultrasonic tone generator can be used of which the signal travels through
smallest openings.
Leak detection in:
 Compressed air lines, gas, vapour and vacuum plants
 Refrigerating plants
 Door seals
Applications:
Sound-proof headset enables
leak detection in extremely
noisy environments
