Gassonic MM0100 / EH6028
Although these calculations are for ideal conditions, where there are no obstacles or reflecting walls
between the leak and the detector, they provide reliable guidelines as to the number of detectors required
and where the might be positioned.
We recommend that the detector should be positioned in line of sight to and with in 8 – 12 metres radius
from the possible leak, to accurately detect leaks of 0.1 kg/sec. (e.g. 4 mm leak size at 735 psi). This may
dependent on local conditions (background noise etc.).
3.2. envIronMental CondItIons
WARNING! In order to keep the detector and the junction box intrinsically safe, the voltage and current
levels must be limited by Ex approved isolators/barriers placed in the non-hazardous area. MTL isolators
are mentioned in drawing BR6008 on page 8. However, any isolators, with the correct specifications, can
be used.
Corrosion Resistant:
The detectors have been tested with salt contamination, followed by 30 cycles of the Kesterwick test
with up to 100% relative humidity and 0.21 SO2 per cycle (according to DIN 5 0 018 - SFW 0.25W). The
Gassonic MM0100 / EH6028 have been tested and found to comply with IP66 according to IEC 529
second edition: 1989-11.
3.3. MoUntInG tHe deteCtor
Two M8 stainless steel bolts attached to the detector’s lid are used to fix the Gassonic MM0100 / EH6028
in its operating position. The detectors can be mounted to a free-standing pole or wall, using the mountain
bracket UA1352. It is possible to mount the detectors no to non-vibrating structural beams or cable-trays.
The microphone should face downwards, and if tilting of the detector is needed, this angle should not
exceed 45°.
