BX280 Toxic and Explosive Gas Detector Control Unit for Industrial use
Cod. BX280 - Toxic and Explosive Gas Detector Control Unit for Industrial use
Through the connection of 2 remote probe, the BX280 control unit has been designed and built according to European regulations to detect the presence of toxic and/ or explosive gas flexibly.
A microprocessor is used to create a complete surveillance and control system with maximum flexibility. Thanks to this and its other features, the BX280 is suitable for civil and industrial applications.
The BX280 control unit has two danger levels:
1st LEVEL, 1st Pre-Alarm. This was set at 13 % of L.E.L. for all probes.
2nd LEVEL, Main Alarm. This was set at 20% of L.E.L.
Other technical features make this control unit extremely versatile and reliable; for example, by using a series of micro-switches it is possible to:
Select or disable the probe when not installed or faulty;
Select the type of gas to be detected (toxic or explosive);
Choose the relay functioning mode (pulsed or continuous);
Choose selection of the intrinsic safety.
