  1. TRANSPORTABLE STAND ALONE MULTIGAS DETECTOR BM 25

  2. STAND ALONE DETECTOR: BM25 • Rugged • Has been specially designed for operation in harsh and corrosive environments • High visibility and audible alarm • Fitted with a large flashing red LED module • and 2 « loud hooters » : 103db/1m.

  3. Safety in the field • Designed for team protection:rescue teams… • Area surveillance for mobile or short term works • Used where fixed detection systems are inapropriate or not present

  4. BM25= rugged MX 2100 version • Keep the MX2100 characteristics and other new functions : • a new king of cells «serie 7/3 » • programmable relay outputs «gas and fault alarms  » • 2 programmable 1/0 inputs • charger input • Trickle chargein EX areas • Safety perimeter • RS485 or radio communication outputs ; (new developments).

  5. Carrying handle Red flashing beacon (protected) Loud hooters sensors 2 connectors (outputs) on each side of casing LCD display protected buttons IP 66 Sizes:467x195x180mm (H P L) Weight :6.8 kgs BM 25: description

  18. BM 25 : batteries • Pack of NiMH batteries (7V2/9AH), rechargeable without opening • Autonomy = according to the configuration : • Up to 170h operations non-stop • Or for example 90 hours with explo/O2 and 2 toxic cells. • Recharged in less than :4h30mn.

  19. BM 25: remote power supply • It’s possible to trickle the BM25 in a classified zone linked with «a remote intrinsic safety power  » (with flammable and toxic cells only) • For these reason,in this case and without alarm, the BM25 will work practically indefinitely !! • But with alarm triggering,batteries will be discharged a bit.

  20. Safety zone Zone 0 ZONE 0 Intrinsically safe remote power supply Remote power supply in a classified zone BM 25

  21. BM25: smart blocks • 1 and 2= mini toxic or O2 smart block of cell • 3= médium toxic or O2 • 4= EXPLO smart block of cell • 5= médium or series 3/7 (new developments). 4 1 2 5 3 Note: without a block somewhere, take in place a dummy cell to keep the index of protection (IP66).

  22. BM25: smart blocks • All the cells are: • « plug in » easy connexion • smart because fitted with a memory of characteristics (type of detected gas, unit, scale, sérial number, usure rate etc… • Pre-calibrated • Interchangeable.

  23. BM25: smart blocks • Channel 5 can be fitted with either a medium cell or a big model (series 3) • Note: BM 25 is fitted with 5 channels but can make a gestion of 4 only! • For this reason if you use the channel N° 5, the 1 st will be automatically inhibited and the cell deactived ! 1 4 2 5 3

  24. BM25: explosible smart-blocks • This channel is obligatory connected with a flammable cell for detection of major explo.gas and 2 types of cell can be used : • catalytic or • catalytic/catharometric .

  25. « universal »: catalytic cell Scale of measurement = 0 to 100% LEL « Non ambiguity measurement message » if the signal is tooà high > 100% LEL Choice of detected explo. gas (preprogrammed list) choice of a special type « all the gas »: the new cell, recently developped by Oldham, will indicate a correct concentration of the explo. gas detected whatever the type and in spite of a unic calibration with CH4 (different curves of explo. gases are very closed). catalytic/catharometric cell: Scale of measurement = 0 to 100%LEL / 0 to 100% gas/ volume with an automatic commutation of scale Note: to use this « LEL/volume » version, it’s obligatory to equip the BM25 with an oxygen cell !

  26. BM25:avaible smart blocks

  27. BM 25 OPTIONS

  28. gaz BM 25: pumping system • Avaible in option: the BM25 can be fitted with an included electric pump • Associated with a remote sampling system (cap of cells and different king of probes) • automatic working pump if a cap fixed….

  29. Optical IR linking for COM 2100 • An IR port located on the right side of BM25 allows the linking to a PC • serial RS232 or USB cables are avaible  • COM 2100 software will recognize automatically a linking to a BM25 or to MX2100 • common software MX2100/BM25.

  30. modules of communication • Each following modules wil be installed on demand in the instrument, outputs will be avaible on right side: • RS485 • 4 to 20 mA • CATEX ( TOTAL) • Others on demand ….

  31. BM25 in the field= example of option (legs) Semi-portable or permanently installed

  32. BM 25 : CERTIFICATIONS • BM25 (fitted with cells) it’s approved intrinsically safety category 1 (very high level of safety) • So usable in zones 0 ! • ATEX II 1 GD EEx ia IIC T4 (except with CO2) • ATEX I M1 (mines) • Other certifications running: INDIA, RUSSIA, CHINA …

  33. BM 25 = very high level of safety ! • The BM25 is a Categorie 1 instrument and can be used in zones 0 and directly in the tank • Using without sampling systems • And with remote informations of alarms…

  34. BM 25 : examples of applications • industrial and maintenance sites • for manipulations of dangerous substances • chemical fire brigades • in tunnels, in confined spaces , in sewers … • wastewater stations • Aircraft maintenance workshops • Coal mines • In storage tanks, underground storage tanks…
