The BXI32 1 to 32 Addressable Gas Detector meets the high European standard for checking for the presence of gas. The unit uses addressable sensors to detect toxic and explosive gases. The display rotates through each sensor and shows gas levels. When unit reaches the pre-alarm levels, it produces a sound signal. A Datalogger stores the alarm history and saves it in memory. If required, a maximum of 50 stored events can printed.

The control unit features two levels of hazard, such as I LEVEL- pre-alarm. This data is variable. Pre-alarm outputs for every sensor can change to suit to the type of plant you want to control. For example, you can select the level from 3% to 16% of LEL or from 45 to 240 ppm.

II LEVEL- general alarm. We set it to 20% of LEL or 300ppm. The control unit has a general alarm relay with/without Positive Safety to enable further control of two solenoid valves. If required, you can also insert up to two relay expansion cards into the BXI32 1 to 32 Addressable Gas Detector.

We also stock the BX316 – a gas detector controller for up to 16 separate toxic or explosive gas sensors. This gas detector is available as an enclosed item IP65 or as a DIN rail mounted module.
