The BExSB1 ideally suits applications requiring a traditional bell sound - designed to warn, call and signal in areas with explosive atmospheres.
The protection type II 2G EEx de IIC T6 allows the signalling bell to be used without restriction in all Ex areas classified Zone 1 or 2.
The signalling bell produces a sound volume of approximately 105dB(A) at 1 metre. The emphasis of the ring is at approximately 1000Hz, as a result of which the signal stands out clearly against lower frequency ambient noises.
We also offer the 'Hootronic’ range which offers the same sound from an all-electronic solution.
Explosion protection is ensured by the flameproof enclosure of the driver system and increased safety terminal box. The enclosure is made completely of GRP (glass-fibre reinforced polyester) thus guaranteeing protection against corrosion. All D.C. versions are equipped with an electronic contact breaker which considerably increases service life compared with other available devices.
