Vacuum leak detector explosion protected electronically operating (VLXE ..), partially explosion protected with integrated pump, for the installation outside of Ex-areas, weatherproof design,
with 500 mbar alarm pressure
with detonation flame arresters in suction and exhaust line
for one above or underground double-walled tank or for above and underground double-walled pipes
with digital manometer (M)
with service indication (Si) indicates the due and prescribed functional test depending on the set maintenance/service interval (time period adjustable between 1 and 63 months)
for the monitoring of water-polluting liquids of those the (possible) explosive vapor-air mixtures (also such ones that can arise through the stored/conveyed liquids in contact with air, humidity, condensation or the materials used) must be classifiable into gas group II A to II B3 as well as in the temperature code T1 to T3, for example: petrol and ethanol-containing fuels, diesel, kerosene, etc.
Vapors must be heavier than air!
If the flash point of the liquid to be monitored requires explosion protection measures, the VLXE .. M can only be used on pressureless tanks.
Otherwise the VLXE .. M can also be used on tanks or pipes with up to 5 bar overpressure.
The international hazardous substances law sets a limit of > 60 °C. National regulations may vary, so in Germany > 55 °C.
